For notes concerning the format and content of this page, see below.

• Idaho:  October - A new power supply along with a back-up battery was installed at Shafer Butte by Steve, N6YIH.
• UVHFS:  October - An unknown transmitter failure on the 145.490 repeater has occurred:  It can "hear" users, but 145.490 is not transmitting.
• UVHFS:  September - The 145.490 repeater on Promontory Point, west of Ogden, was connected to the Intermountain Intertie.  It currently uses a 123.0 Hz tone, but this will be changed to 100.0 Hz in 2019.
• Idaho:  August - The Shafer Butte repeater frequency was changed again - this time to 145.130, once again using a 100.0 Hz tone.
• Idaho:  June - Because of interference issues, the Shafer Butte repeater was changed from 145.230 to 145.270 using a tone of 88.5 Hz to avoid interference problems with Mt. Harrison.

• Idaho:  A replacement for the War Eagle repeater was installed on Shafer Butte near Boise operating on 145.230 using a tone of 100.0 Hz, restoring Intertie coverage to the Boise area.
• Idaho:  An Intertie-connected repeater at Mountain Home on 145.150 - (100 Hz tone) is now available.  Its elevation is not high so its coverage is rather limited.  This site is also used as a relay between Mt. Harrison and Shafer Butte.
  

• Idaho:  The War Eagle mountain repeater on 145.230 was removed from service due to changes in site management.  With the loss of this repeater Intertie connectivity into Boise and parts of west-central Idaho is no longer available.

• UVHFS:  September - A trip was made to the Navajo Mountain site to install UHF gear to allow linking of the Intertie to the Arizona Repeater Association (ARA) system.  The availability of this link is at the discretion of the ARA.
  
• UVHFS:  August - A visit was made to Hidden Peak (a.k.a. "Snowbird") to determine the cause of apparent desense of the 147.180 repeater.  While some desense was initially detected, it seemed that disturbing the coax connections to insert the test equipment caused it to disappear indicating the possibility that a nonlinear junction had formed at or near that connector junction.  A visit was also made to Scott's Hill during the month to replace some of the backup batteries and to make a minor repair on the 145.270 transmitter to restore its proper power output.
  
• UVHFS:  August - Work has been done at Farnsworth Peak  to improve the coverage and performance of both the 147.120 and 146.940 repeaters.  The antenna that had been used for the 146.940 repeater was moved to a location near the top of the tower and a new feedline run.  When tested, however, it was discovered that there appears to be a significant amount of "re-radiation" from some loose hardware on the tower causing intermittent/severe degradation of both the 146.940 and 147.120 repeaters - a problem that has apparently been present for quite a while, but undiagnosed.  While some mitigation of this problem has already been carried out (e.g. securing of some of the loose hardware) additional work remains to be completed.  To minimize these problems, the output power of the 147.120 repeater has been significantly reduced.
  
• UVHFS:  2/13 - the Utah VHF Society held its annual Swap Meet and election meeting in Farmington, Utah at the Legacy Events Center.  Among the items acted upon:
• The 147.120 repeater on Farnsworth Peak was voted to become aligned with the Utah VHF Society.
• By acclamation, the officers of the Utah VHF Society were re-elected in the absence of any nominations for any of the open positions.
• For those UVHFS members who could not be present at the Utah VHF Society swap meet, please contact Mel Parkes, the Utah VHF Society president - link, to obtain your copy of the 2013 booklet.
  
• D-Star Farnsworth:  It has been reported by users that the D-Star stack on Farnsworth Peak is working properly and routing voice packets on the internet as it should.  It is believed that the two 23 cm ports of the stack (the DV - Digital voice and the DD - 128k data) are also working, but since relatively few people have equipment for that frequency/mode, this has not been positively verified.  If you have an Icom ID-1 or equivalent and can test/use the 23cm voice and data ports, please let John Lloyd, K7JL, know whether or not these ports are properly working.
  

2012

• FCC:  It should be noted that in the past several years, the FAA has been replacing their decades-old, very high-power RADAR systems with more modern, much more sensitive low-power systems.  Because of this, the new systems are much more sensitive to possible interference due to amateur operation in the 23cm band and being a secondary user, requiring some amateur users to either QSY (change frequency) or shut down operations entirely.  The UVHFS must keep a close eye on this and work with the ARRL and FAA as necessary.
  
• D-Star Farnsworth:  11/2.  On another trip the UPS was returned with new batteries.  Because of suspected problems, all of the radios except the 70cm DV module  were brought down for bench analysis.  Later analysis on the workbench revealed that there had been some calibration/programming problems related to the 23cm DV and DD radios while the 2 meter radio was properly functional, but likely being impacted by on-site interference.  Later, the radios were re-installed and as far as can be determined are still operating properly.  For a time, internet linking of the D-Star stack was restored, but during the month some of the previously-opened ports got blocked and internet linking is no longer possible:  This issue will (again) be worked out with the site's network administrators.
• D-Star Farnsworth:  11/12.  K7JL and KD7BAY went to Farnsworth Peak to determine why the D-Star stack was not functioning properly.  One of the main problems was that with a change in administration, IP port blocking had restricted access such that internet linking of the D-Star stack was not possible.  In addition to desense, it was discovered that the UPS had bad batteries. and it was brought down.  Analysis determined which ports were the issue and this would be worked out with the network administrators.
  
• Levan Peak Intertie:  10/12.  K7JL and KB7YAF went to Levan Peak to put it and its links back on the air.
• The north UHF link (to Farnsworth) had a blown section on its transmitter and an intermittent short was discovered on one of its internall supply rails - a problem not directly related to the transmitter issue.
• On the south link it was noted that the transmitter power was not getting to the antenna through the T/R relay, so this was removed as it was not needed for this application.  VSWR tests and a visual inspection revealed damage to the south UHF link antenna which should be replaced on the next visit, but there was ample link margin.  
• On the 145.270 side, the transmitter was only producing 4 watts, but this was determined to be a flaky power control adjustment.
  
• Hidden Peak (a.k.a. "Snowbird):  10/12.  The "temporary" antenna installed at Hidden Peak in March was replaced by K7JL and crew with one similar to that which had been broken in the 125+ MPH wind.  This restored the repeater to its original performance.
  
• UVHFS:  5/12.  Due to site coordination issues, the repeaters that had been installed at Bacchus/Rushton would be moved to the Salt Lake Community College.  The affected repeaters are the 146.880, 223.940 and 449.900 and these were moved by KD0J and crew.
  
• Hidden Peak (a.k.a. "Snowbird):  3/12.  The Hidden Peak (a.k.a. "Snowbird") repeater went (mostly) offline on 3/21 when a 125+ MPH wind event broke the VHF antenna at its base:  Their windspeed indicator was pegged at 125 MPH during this event so the actual wind velocity was unknown.  The Snowbird personnel lashed the antenna using a rope to get it out of the tram equipment and prevent further damage.  On 3/23, K7JL and his son, KD7BAY, along with KB7YAF went up there with a new (but smaller) antenna and put it back on the air, albeit with somewhat reduced performance.  Other minor repairs were made to the controller/interface to remedy minor issues that had cropped up in the months before.  The folks as Snowbird were very helpful in taking care of this situation and provided assistance in taking down the old and putting the new antenna.
  
• D-Star IMC:  3/12.  It was reported that the D-Star stack at the IMC was now operational.  See the 11/11 listing.
  
• UVHFS:  1/12.  The status of the 447.225 repeater has again been checked.  N7TDT replied that he still has plans to get this repeater on the air.
  

2011

• D-Star IMC:  11/11.  Coordination has been granted to ARES for a D-Star stack of three voice repeaters to be located atop IHC's IMC, the frequencies being 145.150, 447.950 and 1298.750.
  
• 146.940 Farnsworth:  10/11.  K7JL went to Farnsworth Peak to determine why the 146.940 repeater was performing poorly.  After several hours of investigation, no definitive cause could be found but the replacement of the old antenna improved things very slightly - but the repeater was still mostly unusable to all but mobiles when 147.120 keyed up.  Not directly responsible for the desense, there is something else on site that is re-radiating the 147.120 signal and causing the degradation of the receiver on the 146.940 repeater.  Investigation will have to continue at a later date.  Since this is a prime repeater location at a site with emergency power, it has been suggested that some priority be given to solve this problem when the site becomes accessible again in 2012.
  
• Intertie:  10/11.  A proposal was made to add equipment so that the 146.960 repeater (Francis Peak, above Farmington) could be linked to the intertie.  For the most part, this would be a matter of installing a UHF link radio/antennas.
  
• UVHFS:  8/11.  The 145.350 repeater and its associated HF remote base has be installed near Bacchus.
  
• Jacob's Lake:  8/11.  Using equipment on-hand, W7KBM and WA7GTU went to Jacob's Lake to put the 147.300 repeater back online.  Several problems were encountered with respect to getting the old equipment working again and it is not yet fully operational or on the Intertie.
  
• Jacob's Lake:  7/11.  Local (Kanab) interest has been expressed in putting the Jacob's Lake repeater (147.300) back online and re-interfacing it with the Intertie.  Discussions as to the degree of support by the UVHFS are ongoing.
  
• UVHFS:  6/11.  As noted previously, the Utah VHF Society had been considering "assigning" UHF frequencies for operation of simplex internet-connected nodes (e.g. Echolink, IRLP, DV-Dongle, etc.) to avoid possible interference with coordinated systems.  It should be noted that "assigning" a frequency is not the same as coordinating, but rather implying a "gentleman's agreement" to prevent interference between repeaters inputs/outputs, link frequencies and other users.  At this time, the simplex frequency manager, John, W7CWK, has been working with people with simplex needs to this end.
  
• W7BOZ:  5/11.  W7BOZ has been coordinated 449.300 for a low-level repeater at his Logan QTH.
  
• Herriman ARC:  5/11.  The Herriman group has notified that 449.250 repeater is operational from Herriman High School as KC1F.
  
• ARES:  5/11.  A query was received pertaining to the disposition of the ARRL-affiliated ARES repeaters so research was done in determining ther original intent and current dispostion.  Using paper records with signatures, the following was determined:
• 146.880.  Originally coordinated as a repeater owned by the Utah VHF Society in the early 1970's, it was operated by Pat, W7RQT.  In the late 80's or early 90's, the ARES group requested that they could use it and permission was granted.  There is no record of this repeater changing hands from the UVHFS to ARES, but since they have been using it most heavily, ARES has been maintaining it.  It should be noted that the UVHFS booklets have listed the aforementioned status for many years - at least back into the early 90's.  This repeater has long been located at "Baccus" - which refers to several sites in the same general area.
  
• 224.940.  Located near the VECC site on the west side of the valley, simply called "Rushton" because of local convention.  It, too, is simply called "Bacchus" since that is a more useful name.
• 449.900.  At one time located on Ensign Peak it, too, is located at Rushton/Bacchus.  Since the 90's it has been associated with the local ARES group
  
• UVHFS:  2/11.  The Utah VHF Society has received an exemption related to collecting taxes at the swap meet.  Previously, the UVHFS had to "eat" the estimated sales taxes at the event - a decision made in the interest of maintaining good relations with the sellers present.  With this exemption, the UVHFS is relieved of the direct responsibility of doing this and it is up to the sellers to properly account for and pay the relevant taxes, as has always been the case in years past!
  
• UVHFS:  1/11.  It was noted that the 447.225 repeater (N7TDT) has still been off-air for well over a year without recent updates and the trustee was contacted.  He responded and stated that he was still planning to put it back on the air.
  
• Herriman ARC:  1/11.  The Herriman ARC has requested a low-level UHF repeater pair.  The use of the SNP was suggested for the time-being.
  

2010

• General:  After considerable effort on the part of the utilities, power was gradually restored to the locations mentioned below.
  
• UVHFS:  12/10.  Discussion amongst UVHFS officers and those related to EMCOMM has resulted in the opinion that the link radios at Blowhard, Frisco and elsewhere (as needed) should be replaced as they are 30+ years old.  This was spurred (pun intended!) by the low-level interference generated to another on-site tenant (Air Cell) from the old transceiver.  While not crippling, the links were turned of (except in special cases) to minimize interference and be neighborly - see the 11/10 report, below.  Because these links are critical infrastructure for EMCOMM purposes on the Intertie (e.g. they do not require internet connection to operate, unlike some proposed EMCOMM solutions) the need for upgrade/replacement is arguably more critical.
• General:  12/10 Due to extremely heavy snowfall before 12/22, the power to Blowhard Peak has been interrupted and all radio systems - including the Doppler Radar Site nearby - went offline.  In the general area, several radio stations and other commercial facilities have also gone offline due to loss of power and generator/backup failure.  With the severe conditions, access is currently unsafe/impossible.  This was part of the same storm system that affected Northern Utah and took out the power to Scott's Hill as well as Brighton.
  
• General:  12/10.  Rocky Mtn. Power has reported that the lines feeding Scott's Hill were taken down by falling trees before 12/22 and that the power would be off until after it was safe to access the area.  This affects all amateur repeaters on site, including the 147.270 Intertie and the 146.620 UARC systems.  There is also a widespread power failure in Big Cottonwood Canyon and the ski resorts are adversely affected.
  
• UVHFS:  11/10.  It was observed that the 447.250 repeater was again on the air, this time signing "K7SLC."  It should be noted that no information on this repeater/frequency had been received since 2004 when the original owner, K7MRS (who passed away prior to 4/2008) had updated the frequency coordinator.  According to the conditions of coordination to which the original party had agreed, any changes must be submitted in writing or, at the very least, the coordinator notitifed, or coordination would lapse.  Because of this, the repeater currently on the air using this frequency is not coordinated.
  
• Frisco Peak:  11/10.  It was determined by "Air Cell", an aeronautical "cell phone" provider (e.g. in-flight telephones on commercial aircraft) that low-level local-oscillator leakage was causing interference to them.  While the level of the signal was well within FCC specifications, it was decided - in the interest of being a good neighbor - that the radio(s) radiating the signal(s) should be powered down.  It is likely that this leakage is from power/control lines to/from this receiver.  In the event of an emergency, these links may be remotely commanded back on.  It should be noted that Air Cell has been good to work with and that this interference is not crippling, but only "degrading".  It is worth noting that the affected link radios are original and 30+ years old and should be replaced, anyway.
  
• K7JL:  10/10.  Work was done on the  Laketown-area repeaters by K7JL and K7OGM.  Both the 147.120 and 147.020 were worked on and it was discovered that parts would need to be ordered.  It was also noticed that the NOAA (weather service) transmitter on-site had extremely low audio and the NWS was notified.
  
• Medicine Butte:  10/10.  Work was done to get the Medicine Butte Intertie-linked repeater (146.860 near Evanston, Wyoming) repeater back on the air.  It was discovered that the building supporting the antenna mast had blown over in a very high wind.  The building was righted, its foundation shored up and the inside loaded with a ballast of rocks found on site.  Minor damage was repaired and the repeater placed back online.
  
• WA7X:  9/10.  Work was done to fix a problem with the 70cm port of the 448.150/53.150 repeater. A high VSWR was noted and the antenna was replaced, but feedline issues were also noted which will be addressed on a future trip.  This repeater signs "KI7DX" and one may read about it on the KI7DX Repeater page.  This is not a UVHFS-Affiliated repeater and this was not a UVHFS project, but is mentioned here for completeness.
  
• UVHFS:  9/10.  It was observed that the repeater on 448.875 repeater signed "WB7RVF" - a callsign that expired in 2001.  Upon further investigation was was discovered that it had been mis-programmed and should have been "WB7RPF".
  
• D-Star Farnsworth:  9/10.  John was able to work with KF6RAL and get another 70cm isolator and the 70cm D-Star repeater on Farnsworth is now back in operation.
  
• Mapleton ERC:  9/10.  The Mapleton ERC group wishes to put a low-level repeater on 146.800:  To do this they will need to get a written sharing agreement from the trustee of the Sedgwick repeater in Idaho on this same frequency.
  
• UVHFS:  8/10.  The relevant parties requested (and received) a change so that the 447.900 repeater would be listed as being affiliated with OLRC and SJord as the RMRA is no longer extant.
  
• D-Star Farnsworth:  7/10.  It has been observed that the transmit signal strength of the KF6RAL 70cm D-Star repeater has decreased by about 20dB.  Note:  It was determined shortly after this that the 70cm isolator had failed open.
  
• UVHFS:  7/10.  WA7GTU, W7KBM and N7KM went to Frisco Peak to replace failed tone decoder(s).  With additional circuit protection and different mounting it is hoped that these encoders will not be damaged again by transients/lightning or whatever it is that seems to like to kill them.
  
• Hidden Peak Intertie:  6/10.  The north link (Hidden Peak to Malad) is offline due to a problem at Malad and site access is not currently possible due to conditions.
  
• Park City:  6/10.  The status of the 145.230 repeater in Park City is unknown and the contact information is not longer valid.  It appears to be off-air.
  
• UVHFS:  6/10.  The question of frequency on which testing of a "D-Star Hotspot" could be operated has come up.  It was noted to the questioner that while the very low power of the hot spot itself is unlikely to cause a problem, the much higher power of the radio used with it (e.g. an HT running 1/2 watt) could be an issue.  The UVHFS should consider recommending a UHF simplex frequency on which such gear could be operated without causing interference to existing systems.
  
• UVHFS:  6/10.  The trustee of the 146.740 repeater near Enterprise, Utah has notified the UVHFS of a correction to the database as to its location.
  
• UVHFS:  4/10.  It has been observed that the 447.250 repeater pair, formerly coordinated to Russ Scholz, has been left "fallow" since some time after his passing.  According to the coordination rules to which the original owner/trustee agreed, coordination of this pair has lapsed and is no longer extant.
  
• UVHFS:  4/10.  W7RSS has released the 449.075 repeater pair and it is now available for possible use.
  
• UVHFS Swap Meet:  2/10.  At the business meeting at the Utah VHF Society Swap Meet held on 2/27/2010 it was voted to:
• Purchase a Yaesu FT-857 or FT-897, tuner, power supply and HF antenna (dipole-type or vertical) to complete the remote base HF station tied to the 145.350 repeater.
• Purchase an 8-port repeater controller for Farnsworth Peak to upgrade its interface to the Intermountain Intertie.
• UHF Bandpass filter for Frisco Peak to accommodate new requirements.
  
• Allow Blowhard and Jacob Lake linking.  This will likely be done with gear on-hand and need only site-specific items (e.g. crystals, feedline/connectors, antenna.)
• Minor upgrades to Scott's Hill (145.270.)
• Minor expenses (e.g. envelopes, paper, postage) related to the operation of the UVHFS.
• Pay sales Tax for the swap meet owing to a "crackdown" by the state since individual vendors did not file.  We will look into obtaining an exemption status from the state.
  
• Farnsworth Peak Intertie:  2/10.  The link south from Farnsworth to Levan peak is offline owing to a transmitter failure at Farnsworth, effectively isolation Levan Peak from the Intertie.  It is hoped that this transmitter can be repaired soon.
  

2009

• Frisco Peak Intertie:  11/09.  W7WFW and WA7GTU went to Frisco Peak on the 22nd and restored the link between it and Blowhard.
  
• UVHFS:  11/09.  There seems to be an errant node on 146.46 Mhz.  Update:  This node was DFed and found to be at the State Capitol.  Control of it was re-established and it was disabled.
  
• UVHFS:  11/09.  The 145.370 (formerly at Tower Mountain in Utah County) will be moving to a location west of Magna.  It should be noted that doing so risks the loss of this frequency's status as a "Wide Coverage" repeater.
  
• UVHFS:  10/09.  It was noted that there is an IRLP node (#3125) on the 449.725 repeater that does not appear in the listings as determined from activity on that frequency.
  
• UVHFS:  10/09.  As voted on at the 2009 UVHFS Swap meet, the HF remote base and repeater is taking shape an in its testing phase.  It is anticipated that this will be installed at a site on the west site of the Salt Lake valley for which there is an existing agreement.
  
• UVHFS:  10/09.  A complaint was received about interference between a a repeater in Las Vegas and a link frequency.  It appears as though the Las Vegas group moved from a low-level to a mountaintop location, causing interference:  The Nevada coordinator and the owner of that repeater have been notified.
  
• ARRL/UVHFS:  10/09.  The ARRL has approved a study to determine the practicality and benefits of amateur operations to migrate to narrower-bandwidth operations on the VHF and UHF amateur bands (e.g. from +/-5kHz deviation FM to "narrowband" +/-2.5 kHz deviation and digital system) and the Utah VHF Society and frequency coordinator will closely follow this as technology evolves and needs develop.  It should be noted that earlier (2008) the Utah VHF Society had determined that a minimum 12.5 kHz spacing was required for reliable adjacent-channel D-Star operations and that 15 kHz (minimum) was required between a D-Star and analog channel.  The UVHFS had also realigned the bottom several 2 meter repeater pairs (starting at 145.1125 MHz) narrowband digital pairs with 12.5 kHz spacing.
• K7JL:  9/09.  John, K7JL has gotten the D-Star Stack provided by KF6RAL installed and (mostly) working on Farnsworth Peak.  There are some on-site desense issues that need to be resolved as well as coordinating of IP ports with the network administrators to allow internet access for the D-Star stack.  This stack includes 2 meter, 70cm, and 23cm voice (DV) repeaters as well as a half-duplex 23cm digital (DD) unit.
  
• UARC - 146.620 System:  9/09.  The Utah Amateur Radio Club has informed the frequency coordinator that the 146.620 Synchronous/Voting repeater system is now in full operation.  This consists of a pair of repeaters - both using the 146.020/146.620 channel with one on Scott's Hill above Brighton, Utah and the previously-existing repeater on Farnsworth Peak.  These operate as a single repeater with overlapping coverage.  More information may be found at the UARC 146.620 Repeater System web page.
  
• UVHFS:  9/09.  Based on an update from the owner, the W7DBA 448.025 repeater in Huntsville is now listed as being active.
  
• UVHFS:  8/09.  The use of 146.650 for Echolink Simplex by Cottonwood City was discontinued.  Clarifying their needs, the UVHFS has worked with them so that future problems can be prevented.  Closer attention is to be given to maintain better contact with the various groups using/sharing simplex frequencies for this sort of purpose as well as their normal nets to reduce the likelihood of interference.
  
• UVHFS:  8/09.  The N7TDT repeater (447.225) had been off the air for months and with the need for UHF repeater pairs, updates on the status were requested of the owner to verify that the pair was going to be used in the future.
  
• UVHFS:  8/09.  Because of change in ownership of the site and greatly increased rental fees, the 145.370 repeater would be moving from Tower Mountain.
  
• UVHFS:  8/09.  SDARC has requested that the 147.080 repeater should move to Lake Mountain and that some of the UHF links would be reconfigured.  Recoordination was completed and work commenced.
  
• UVHFS:  7/09.  UARC has obtained from the Utah VHF Society some pieces of equipment (namely several GE MVP chassis) that will be used for the full-duplex UHF links between Scott's Hill and Farnsworth for the 146.620 synchronous repeater project.
  
• UVHFS:  7/09.  Simplex Echolink operation has been observed on 146.650 from Cottonwood City, making both 146.640 and 146.660 operation - both common from the Wasatch Front - impossible when the Echolink node comes up.  This is in violation of the 20 kHz band plan.
  
• Blowhard Intertie:  6/09.  WA7GTU and WV7H went to Blowhard (on their own dime!) to investigate a problem with the 146.80 repeater.  Expecting mainly duplexer issues, they discovered that various portions of its transmitter had incinerated themselves and that the main transmit antenna was damaged and will likely need to be replaced.  A "temporary" repair will be implemented in the next couple of days to make the repeater usable until a permanent repair can be effected.
  
• D-Star Ogden:  6/09.  D-Star repeater pair on 447.950 coordinated for use at the Ogden Sheriff's office.
  
• UVHFS:  4/09.  The frequency of 145.670 has been proposed as a simplex frequency for D-Star along the Wasatch Front.  Note that this is not a coordination, but rather to inform so that this sort of operation may occur under the "gentleman's agreements" under which most simplex operation occurs on the amateur bands.
  
• Frisco Peak:  3/09.  Frisco Peak is back online thanks to someone with whom Don, WA7GTU had been in contact who had business on site and corrected the power problem.
  
• FCC:  3/09.  In a clarification, WB6YRU filed and FCC petition to clarify the definition of a "repeater".  This came about because of the word "simultaneous" in Part 97, Section 3(a)(39).  The FCC indicated that "simultaneous" referred to an active transmitter at the station being active at the same time as a receiver and a system with a delay incurred in the system (e.g. digital delay as would be the case with digital voice) would still be "simultaneous."  Reference:  ARLB018, 24 March, 2009.
  
• Frisco Peak:  2/09.  Due to a power problem, the amateur gear on Frisco Peak was offline.  This will be investigated as soon as possible.
  
• UVHFS:  2/09.  It was noted that the 448.825 repeater still signs "KD7PB" even though the licensee has changed calls:  The trustee was notified.
  
• UVHFS:  2/09.  The W7TEU (147.220 MHz in Box Elder County) status was updated with the emphasis that it not cause interference to a repeater on the same frequency in Utah County:  No such interference has been reported.
  

2008

• UVHFS:  9/08.  The W7XDX repeater on the 33cm band (927.1125 MHz) was reported to now be operating from Butterfield Peak.
• UVHFS:  9/08.  Extensive work was done at Navajo mountain and other sites in southern Utah to restore its proper operation and coverage as well as to allow it to be linked to the Intertie.  It should be noted that most of the expense involved was actually that of transportation, food and lodging - all of which was borne by the participants themselves.
  
• UVHFS:  9/08.  WA7GTU, W7KBM, WV7H installed link radios at Blowhard to allow the 146.960 Navajo mountain to be connected to the Intertie.
  
• D-Star:  9/08.  As the result of additional testing with D-Star equipment, a web page was created that outlines the nature of the codec used in D-Star and important considerations that should be taken when it is used - particularly in EMCOMM (Emergency Communications) situations.  Link:  D-Star Codec Behavior.
  
• Scott's Hill Intertie:  8/08.  The Scott's Hill 145.270 repeater was repaired and put back online.
• Levan Peak Intertie:  8/08.  The UHF Intertie link antenna to Levan was upgraded to make communications more reliable.
  
• Scott's Hill Intertie:  7/08.  The Scott's Hill 145.270 Intertie-linked repeater was damaged by a severe power disturbance.  A repair project is in planned once it has been verified that the road is open for the season and the nature of the problem is determined.
  
• UVHFS:  5/08.  K7MLA notified that 448.875 was undergoing testing after having changed hands, having been donated to the .  The appropriate re-coordination process was begun.
  
• UVHFS:  4/08.  NV7V notified the UVHFS that 447.000 repeater would be off air for a while for a rebuild.
  
• UVHFS:  4/08. N7EVC was contacted as to the disposition of his 447.425 repeater which had been previously proposed.  Based on his response, additional time was given to get it on the air pending a sharing agreement with the owner of another repeater in the area on the same frequency.
  
• D-Star and other digital audio:  3/08.  As per prior analysis and measurement and with the approval received (see below) the former 1200 baud packet repeater pairs were realigned for use by digital audio system such as D-Star.  The repeater pairs will use standard -600 kHz split and 12.5 kHz spacing.  In those instances where there is already existing infrastructure (e.g. the 145.190 analog repeater) protection would be offered between those and proposed systems to avoid interference.  The frequencies are:
• 145.1125
• 145.1250
• 145.1375
• 145.1500
• 145.1625
• 145.1750
• 145.1875
  
• UVHFS Swapmeet:  2/08.  At the Utah VHF Society Swapmeet:
• In a sub-gathering of repeater operators and others the idea of releasing what had been 1200 baud packet repeater pairs and re-allocating them for D-Star and other digital audio use was discussed.  No-one present - which included those who had interest in packet operation - objected in re-purposing these frequencies.  This was then brought up to the general attendance an no-one voiced an objection provided that accommodation be made for the existing 145.190 repeater operated by the IHC club.
• BARC (Bridgerland Amateur Radio Club) is planning a major repair and upgrade for the Mt. Logan repeater, a project expected to cost about $4000.  It was agreed that the Utah VHF Society would provide about 25% of this amount.
  
• D-Star:  2/08.  Based on the testing of three different D-Star capable transceivers, the analysis of the specifications of the IF filtering contained in these radios, their actual occupied bandwidth and adjacent-channel and interference potential testing of the three D-Star radios and a larger number of typical analog FM radios, a recommendation has been made with respect to D-Star to D-Star and D-Star to Analog channel spacing:
• D-Star to D-Star channel spacing:  12.5 kHz
• D-Star to Analog (+/-5 kHz deviation) channel spacing:  15 kHz
• For more information on these recommendations, please read see the D-Star Channel Spacing page.
  
• UVHFS:  1/08.  The first results of the D-Star testing - now running for several days with the cooperation of others along the Wasatch Front - are coming in.  In the absence of multipath, a "noisy but copiable" analog signal correlates with a marginal D-Star signal.
  
• D-Start:  1/08.  With the increasing D-Star activity, it was observed that the available information from ICOM and other sources does not include the technical data required to properly maintain D-Star radio equipment or make an informed decision as to the necessary channel spacing between adjacent D-Star channels or between a D-Star channel and a conventional FM analog channel as well as.  Because of this, the Utah VHF Society has begun a program of bench-top and real-world analyses to determine important aspects of D-Star operation before committing to coordinate frequencies.  This testing included the temporary testing of alternating D-Star and analog transmissions on 145.170 MHz to determine propagation and A/B comparisons of analog and digital signals from the same transmitter at the same power level.
  
• UVHFS:  1/08.  Clarification of the disposition of the 449.300 portable repeater for use in Davis County and surroundings for emergency purposes.
  
• UVHFS:  1/08.  John Lloyd, K7JL continues to contact several repeater operators for updates/clarification due to the impending deadline for information for the ARRL Repeater Directory.

2007

• UVHFS:  12/07.  Request for more information from KR7D about its apparent linking of the 147.220 and 145.430 repeaters in Utah County, this being done in order to ascertain the possible frequency-reuse of 147.220 in Northern Utah.
  
• UVHFS:  11/07.  Request made to coordinate a UHF repeater near Duck Creek Village, UT by K7KF
  
• Farnsworth Intertie:  11/07.  Work has been completed at Farnsworth Peak and the link to Levan Peak is now operational.
  
• Frisco Peak Intertie:  10/07.  The replacement of the tower at Frisco Peak has been completed with the old antennas transferred and the old tower has been removed, this in response to the observation that the original tower was damaged and beyond economical repair.  Repairs were also completed on the link radios and the 146.94 repeater.  It should be noted that this work took several people several days and that the participants bore the travel/food/lodging expenses involved.
  
• Levan Peak Intertie:  10/07.  Work on the Levan Peak repeater and link has been completed and is operational.
  
• SDARC:  10/07.  In response to an emergency request, the Utah VHF Society has made available $980.00 to the Sinbad Desert Amateur Radio Club (SDARC) for emergency replacement of radio gear that had been destroyed by lightning.  The SDARC, although not very large in membership numbers, maintains a linked repeater system that covers most of southeastern Utah by the commendable and dedicated efforts of everyone involved.  Even though the SDARC is not currently a UVHFS-aligned organization, this request was granted due to the importance of this system to the amateur population in general.
• Hidden Peak Intertie:  9/07.  A power transient damaged the controller at the Hidden Peak (a.k.a. Snowbird.)  The controller was taken down to the valley and repaired, but awaiting full testing and enough time time to visit the site.  Because this radio site is accessible year-round, priority has been placed on completing work at those other pending sites that do not have winter access.
  
• UVHFS Swapmeet:  2/24/07.  At the annual Utah VHF Society Swapmeet and business meeting.   Several items of business were conducted during this meeting.  By acclamation, the previous years' officers were re-elected.  These officers are:  President, Mel Parkes, NM7P;  Vice President, Don Blanchard, WA7GTU;  Secretary, John Mabey, W7CWK;  Treasurer, Danny Fullerton, KC7RUF;  and Frequency Coordinator, John Lloyd, K7JL.

Additional items voted on by the membership were:

• Unanimous vote approving the revised Utah VHF Society Bylaws.
• Appropriation of monies for other projects.

2006

• UVHFS Swapmeet:  2/25/06.  At the annual Utah VHF Society Swapmeet and business meeting.   Several items of business were conducted during this meeting.  By acclamation, the previous years' officers were re-elected, with no other candidates having been proposed for office.  These officers are:  President, Mel Parkes, NM7P;  Vice President, Don Blanchard, WA7GTU;  Secretary, John Mabey, W7CWK;  Treasurer, Danny Fullerton, KC7RUF;  and Frequency Coordinator, John Lloyd, K7JL.

Additional items voted on by the membership were:

• Unanimous vote to provide a sum of $1000 to the Ogden Amateur Radio Club for upgrades to their club repeaters.
  
• Unanimous vote to provide purchase a new set of duplexers for the 146.80 MHz Blowhard Peak VHF Repeater.  No fixed dollar amount was set, but this is expected to be under $2000.
  
• Unanimous vote to provide "seed" money for a planned 2006 WIMU Hamfest in the amount of $250.
• Unanimous vote to more rigidly enforce frequency coordination rules to reduce the number of "paper" repeaters.
  

It was also announced to the membership present that it had been proposed to replace the Utah VHF Society Bylaws with updated instruments - See the next item, below.

• UVHFS:  2/06.  Mel Parkes, the Utah VHF Society president, has proposed a significant revision of the documents that govern the Utah VHF Society in order to both clarify and modernize them.  A proposed draft may be see online at the following link:  Proposed Utah VHF Society Constitution.  This document will appear at this link for the next several months, revised as necessary according to suggestions and need, and will be voted upon by a quorum of members over the next several months.  If you wish to suggest changes to this document, please send an email to the Utah VHF Society President or another Utah VHF Society officer.
  
• UVHFS:  1/06.  The Utah VHF Society Website now has a new URL:  utahvhfs.org.  The old URL will continue to work for the foreseeable future, but I'm sure that you agree that the new one is much easier to remember.

2005

• UVHFS:  11/05.  With the help of Gordon, K7HFV, the repeater listing database is once again automatically updated and a "raw" data file is available once again.  One of the more useful new features is a "detail" page for each repeater that displays information that simply would not fit in a simple listing, such as:
• The latitude/longitude of the repeater itself.
• The site elevation.
  
• Various details of the repeater operation, such as autopatch, weather, open/closed, internet linking, wide area coverage, etc.
• The name of the sponsoring organization of the repeater, rather than just an acronym.
• Expanded details related to the footnotes in the database.
• A description of the approximate coverage area of the repeater.
• A link to a web site with more information about the repeater.

For many repeaters, not all of this information is available so if you can supply missing or updated information about a particular repeater, or if you have comments about how the information is presented on these pages, please contact the frequency coordinator with that information.  Please note that work on these pages continues, so the format and layout may change slightly over time.

• UVHFS:  10/05.  The script that is used to automatically update the repeater listings is once again in operation.  This script takes the frequency coordinator's database and formats it into web page format as well as producing a "raw" data file for use by others.  Additional enhancements will follow in the coming months...
• Frisco Peak Intertie:  9/05.  Don, WA7GTU, has completed repairs and replacement of equipment and antennas on Frisco Peak and the Intertie's UHF link between southern and northern Utah is once again in operation.
• K7HEN:  5/05.  Mack, K7HEN is in the process of relocating the 147.24(+) Tabby Mountain repeater.  This relocation has been necessitated by the recent requirement of a $3000 fee (having to do with School Trust lands) that cannot be borne by the volunteers that support this system.  The new site will be on Cedar Mountain (near Fruitland) and will offer coverage very similar to that of the Tabby Mountain repeater and it will also be linked to a site near Lewis Peak and to Butterfield Peak.  This reconfiguration of the system is expected to occur sometime over the summer.
• WA7GTU:  5/05.  Don, WA7GTU reports that as of 5/19/05 the "Cedar City" 146.94(-) repeater (actually, it's closer to Milford) is down due to equipment failure - possibly a 2 meter receiver.  For safety, the transmitter and the other links have been turned off until repairs can be made.  This failure effectively severs the link between the Wasatch Front and points southward, into St. George and Las Vegas.
• Hidden Peak Intertie:  3/05.  John, K7JL, reports the failure of a link transmitter that ties the Intermountain Intertie's main hub repeater on Snowbird Peak (147.18+) to the 147.12(+) repeater on Farnsworth Peak.  The failed transmitter, on Snowbird Peak, will be replaced as soon as time and weather permits.
• UVHFS Swapmeet:  2/05.  The body of the Utah VHF Society Membership voted, at the annual meeting held in conjunction with the swapmeet, to align the following repeaters with the Utah VHF society:
• 146.70, Ensign Peak.  This repeater covers the Salt Lake valley and Davis counties and is operated by Salt Lake County ARES.
• 449.90.  This repeater, located in the foothills of the Oquirrhs, shares the site with the already-coordinated 146.88 repeater operated by Salt Lake County ARES.
• Two other repeaters, one of them in the Cache valley area, were considered for alignment, but this was shelved pending further developments on the parts of the repeater operators.

2004

• K7DSN:  9/04.  A repeater on 447.400 has gone into operation from Teat Peak.
• UVHFS:  4/04.  A repeater on the under-utilized 222 MHz band is scheduled to be installed at Mt. Harrison north of the Utah-Idaho border.  This repeater will have wide coverage extending into large portions of Box Elder, Weber, and northern Davis counties.
• UVHFS:  4/04.  There are increasing numbers of "incidents" involving "simplex" IRLP/Echolink nodes and/or crossband repeaters.  There have been several recent occasions where one of these types of systems will suddenly appear on the air with no apparent means of control.  On several occasions, these have disrupted repeater operations and/or simplex operations on the frequency.  Please remember that such unattended operations with no means of control are illegal - and, at the very least, represent poor operating practices.  Several of these systems have had no apparent ID - a fact that makes it more difficult to contact the responsible party.  Reports of such systems are routinely forwarded to our local Official Observers.
• UARC:  4/04.  Work continues on interfacing the 146.76 UARC repeater (on Lake Mountain, west of Orem) to IRLP.  See the UARC IRLP page for more info.
• KB7OGM:  4/04.  Eldon reports continued progress on installing a new "intertie-linked" repeater near Montpelier Idaho near the north end of Bear Lake.  This repeater will be on 147.12+ and fill in the gaps in coverage at the northern end of the lake.
• UVHFS:  4/04.  There is increasing pressure on our 2 meter simplex frequencies.  Please remember that these frequencies are a resource shared amongst all parties.  Please refer to the Simplex Frequency Assignments page for more info on who is on which frequency and when.
• Levan Peak Intertie:  4/04.  Work is resuming on the 145.27 repeater to be installed at Levan Peak.  This repeater will be part of the Intermountain Intertie and will provide an additional link to the intertie's repeaters in the southern part of the state.
• K7QEQ: 3/04.  Royce, trustee of the Moab 146.76 repeater, requests "de-alignment" from the Utah VHF Society as he has made no requests for UVHFS support for well over a decade.  Because this requires a vote by a quorum of members, it is likely that this will not officially happen until the next vote at a UVHFS Swapmeet.
• UVHFS:  2/04.  At the swapmeet, it was voted that two of the packet repeater frequencies, 145.190 and 145.170, be made available for voice repeater operation.
• KJ7YE:  1/04.  Robert reports that he has put the 223.880 repeater on the air from Eden.

2003

• K7OJU:  11/03.  Dave reports that the trustee of the 448.000 and 1285.000 MHz repeaters, W2IO, has moved from the Salt Lake area and that he has assumed responsibility of these repeaters.
• IHC Radio Club:  11/03.  The Intermountain Health Care Radio Club (W7IHC) purchased the 448.550 repeater and has installed it at their station in West Valley.  This repeater was re-coordinated as necessary.
• WA7GTU:  Don Blanchard reports that as of 9/03, the 146.34-94 repeater on Frisco Peak is not using a subaudible tone decoder.  This means that, for the moment, a tone is not required to access this repeater.  The tone decoders were damaged by lightning and the feature was disabled.  It is expected that tones will be required in the future, once the decoders are replaced/repaired.

2002

• WA7GTU:  The following is an update from Don Blanchard, WA7GTU:   "Because of interference from other sources at Frisco Peak, the 100 Hz PL on 146.34-94 has been activated, at least for the present time.  In the event that you do not have PL it is still possible to use the repeater and link system.  Sending the command *870 will turn the PL requirement off and *879 will turn the PL requirement back on.  Keep in mind that you will not get a squelch tail until it is functioned off.  Please turn the PL back on when you are finished.  When the control codes are properly decoded you will get a command complete beep.  There may be a timer function in the software (not verified) that will turn the PL back on automatically after a period of time."  (12/20/02)
• Frisco Peak Intertie:  On 12/13/02 Don Blanchard, WA7GTU, made a trip to Frisco Peak to work on that site's connection to the Intermountain Intertie, among other things.  Various adjustments were made which allowed the North/South link that connects Northern and Southern Utah to be put back online.  Please note that this link is still experiencing occasional fades, but is generally working well.  Further improvements are planned as time/weather permits.  (12/02)
• UVHFS:  Beginning January 2003, the weekly Utah VHF Society Swap and Traffic Net will be held on the 147.12+ repeater.  The '12 repeater has better coverage of the northern part of the Wasatch Front  than the 146.94 repeater and it is linked to the Intermountain Intertie.  This increased coverage will allow a greater number of people to participate in the net.  (12/02)
• UVHFS:   The annual UVHFS swap meet is to be held on Saturday, February 22, 2003 in the Zion building at the Utah State Fairpark.  Doors open at 8:00 A.M.  (12/02)
• OARC:  As of 9/2002, two repeaters of the Ogden Amateur Radio Club (OARC) have returned to the air:  146.82, Mount Ogden and 146.90, Little Mtn.
• UVHFS:  The 145.35- repeater was voted by the membership to be aligned with the Utah VHF Society.  This repeater has been on air testing intermittently.  This repeater will be installed at one of three locations: 1)  Summit Park area along I-80 near Park City.  2)  Point of the Mountain between Lehi and Draper.  3)  In the foothills of the Oquirrh mountains along highway 111 in the vicinity of 5400 South. (Date of action:  2/24/2001, at the 2001 UVHFS swap meet.) As of 12/2002, this repeater has not been installed in a permanent location.
• UVHFS:  As of 6/2002, permission was obtained by the UVHFS to place a repeater on Levan Peak.  This repeater will be part of the Intermountain Intertie and operate on 145.27, a frequency shared by two other repeaters in the same system.  The two other repeaters are on Scott's Hill - near Guardsman Pass near the town of Brighton, and Mount Harrison in southern Idaho.  Analysis shows that there should be minimal overlap amongst these sites in populated areas, with any overlap being at least partially mitigated by the fact that they will all generally carry the same audio source.  This repeater will provide additional coverage in the center of the state, including Sanpete Valley to the east, and to the west of Delta.  (Date of action:  8/2002, by the UVHFS officers.)

2001 and earlier

• UVHFS:  The 146.80- repeater was voted by the membership to be aligned with the Utah VHF Society.  This repeater is located atop Blowhard Peak in southern Utah.  This repeater provides coverage into Panguitch, Kanab, and other communities and covers a large portion of rural southern Utah.  This repeater is normally connected to the Intermountain Intertie.  (Date of action:  2/24/2001, at the 2001 UVHFS swap meet.)
• UVHFS:  The 147.22+ repeater was voted by the membership to be de-aligned with the Utah VHF Society.  This repeater was formerly located at the point of the mountain (one of the suggested sites of the 145.35 repeater above.)  Recent gravel mining required that the original site be relocated and the owner of this repeater (WA7YZR) chose not to locate his repeater at the new site and moved it to his personal residence.  The membership decided that this repeater no longer meets the requirements for UVHFS alignment. (Date of action:  2/24/2001, at the 2001 UVHFS swap meet.)
