CARP Repeater Update 2017-1119

Hello fellow club members and others licensed to use amateur radio repeaters.

On Saturday Nov. 18, a few changes were made to the C.A.R.P. repeaters at the Mile High location:

  • The club is now using new Yaesu repeaters at the Mile High site on 2m and 70cm FM replacing older equipment.
  • A new controller system was also deployed. This will allow robust control and features in the future.
  • The Mile High VHF and UHF repeaters are now linked using the new controllers.
  • A donated coaxial patch cable replaced an older and lower performance one on the UHF repeater.
  • The 1.25m repeater is offline in an effort to incorporate it with the new controller. While the linking was successful to the other repeaters, a problem arose on the RX side of the 220 repeater into the new controller. No ETA at this time for re-deployment.
  • Adjustments were also made to reduce the intermittent RFI on the 70cm repeater. Initial results are positive. We will continue to monitor and address as needed.
  • Courtesy tones are being used. Two beeps are heard if the RX station is on the same repeater as the TX station (400 Hz = 2m) (600 Hz = 1.25m) (800 Hz = 70cm)
  • Three increasing tone beeps are heard if the TX station is coming in on a linked repeater.

Please note, this is always a work in progress. We are amateurs in the true meaning of the word and enjoy what we do. While we noted improved receive during initial testing with the new equipment, further testing will be conducted for both TX and RX in the coming days, months and years to come. Even if our equipment remained constant, the environment changes with potential increased RFI from other radio services, which we are currently experiencing and addressing. The C.A.R.P. website has the current status of the club repeater system.

The Clovis Amateur Radio Pioneers club has always promoted experimenting and testing new technology. We endeavor to continue this effort. In the near future we plan to request information from club members about the amateur bands they are able to TX and RX based on their current radio systems. We will use this information to drive our efforts in things such as meeting presentations as well as potential development and deployment of amateur radio services.

Hardware updates cost money. While club members volunteer their time to research, configure and install, the hardware itself has costs. Some of it is donated, but most of it is paid for from the efforts of only a few members at our fundraising fireworks stand. The C.A.R.P. board endeavors to keep club dues from increasing by asking the membership at large to donate some time once a year with assistance operating the fireworks stand. This single event is key towards covering costs for the repeater system upgrades, insurance, monthly meeting facilities, camping and field day events, as well as the year end club party and much more. If most members were able to spend four hours of time at the stand once a year, it would allow us to keep the stand operating every permitted day. With limited operating hours the funds will decrease.

On behalf of the C.A.R.P. board of directors, I hope you enjoy using the carp repeater system for personal enjoyment and assistance with community based activities.

Respectfully yours,

Rick Tyburski
