Our repeaters and this page are going through some change.  Please bear with us

145.27mHz: -600kHz offset, 107.2Hz tone . 
We have relinquished these frequency pairs.

  • Repeater is hosted by K2SS at his N7TU contest station in Vail, AZ.
  •  The Radio and Duplexer are located in his garage.
  • Power is provided off the normal grid feed but can also be provided by a solar system with Tesla Powerwall storage. Thus, it can potentially provide communication support during blackout conditions.
  • Antenna is a Diamond A144-S10 ten element Yagi with 11.6 dBi gain. 
  • The antenna is pointed 245 true with a beam width of about 40 degrees at the -3dB points.
  • The antenna is located at 30ft above ground on a Rohn 55 tower.​
  • Tower coordinates are 31°55'54.87"N 110°45'11.08"W.
  • The power out of a WACOM six cavity duplex is 35 Watts.
  • The coax loss from the duplexer to the antenna is estimated to be 3dB.

Good news GVARCians
Echolink has returned to GVARC.
Whether using the apps or PC software, just search N7GV, and it will popup. Then connect.
It will be connecting to the 145.29 repeater.

We are no longer connected to the WINS System.
