Simplex Repeater Controller (190-0345) Operation Faxback Doc. # 50494 To work with the Simplex Repeater Controller, all transceivers you want to communicate with must be on the same frequency and have the same capabilities (e.g. CTCSS or any type of private line encoding or decoding). For the best range, place the repeater radio's antenna as high as possible. 1. Turn on the transceiver you connected to the repeater, set the volume to its lowest level, and adjust the squelch control to its mid-point. 2. Turn on a second transceiver, set the volume to its mid-point, and turn the squelch control clockwise until the hissing sound stops. Hold down PTT (push-to-talk) on this second transceiver without talking into its microphone. 3. Slowly increase the volume on the transceiver you connected to the repeater until the indicator on the repeater lights steadily. Then increase the transceiver's volume slightly. 4. Release PTT on the second transceiver. 5. Adjust the volume level on the transceiver you connected to the repeater to the desired level. 6. Press PTT on the second transceiver and wait 1 second, then speak into the microphone. Release the button when you finish speaking. The repeater repeats your transmission. All other transceivers that are on the same frequency and within range of the transceiver you connected to the receiver receive your transmission. (EB 11/03/98)
