Trimble R7 GPS Receiver Operation
By default, the internal UHF radio has only a few frequencies installed.
Use the WinFlash software to configure additional frequencies. For
more information, see Adding frequencies for the 450 MHz internal
radio, page 71.
External radio setup
To use an external radio with the Trimble R7 receiver, you need an
external power source for the radio.
To set up a Trimble R7 receiver using an external radio:
1. Connect one end of the yellow GPS antenna cable to the yellow
TNC port on the receiver.
2. Connect the other end of the GPS antenna cable to a Zephyr or
Zephyr Geodetic antenna.
3. Connect the external radio to Port 3 on the receiver.
4. Connect a radio antenna to the external radio.
