In preparing for setting up and testing our simplex network you should set up your radio or radios on GMRS 22R (repeater) and 22S (simplex). If you have a radio with dual VFO’s you can set one VFO to each channel. This will make it easy to monitor both at once for testing. If your radio doesn’t have dual VFO’s you can either use two radios or just switch frequencies when testing.
For ease of memory, 🙂 we have set the tones the same for both the repeater and simplex 22 channel. TX D131N RX D131N.
