Information for the RR725 GMRS Repeater in North Austin, Texas

Currently the Round Rock 725 (RR725) repeater system is a Simplex Parrot Repeater (save and repeat) on 462.7250MHz (CH 22, in the GMRS radio band.) It was designed to allow local residents to use it while also being portable enough to take as an emergency repeater with a battery box. I will be posting images as I take them of this project. You can also check our our YouTube channel for reviews, guides and videos on the project and others.

The hardware currently consists of:

  • Surecom SR-112 Repeater controller
  • Baofeng GMRS-15 Pro 5 watt Handheld
  • Nagoya 771G Whip Antenna
  • Custom 30Ah 12V (360Wh) LifePO4 Battery Box with built in solar charge controller.
The repeater is set to announce the call-sign every 15 minutes in CW (Morse Code). If you hear it then you are in range of the repeater. Unfortunatly how low it sits in the Round Rock Valley there are a lot of obstructions. This is a build in progress and will have updates as funds allow.
