Hello to the group. Does anyone have any documentation or information on the Spectrum SCR 77 220 Mhz repeater? I am trying to repair one of these animals that has no Rx audio. It would appear that there is no discrimiator audio out either so I believe that the problem is in the Rx board not just the audio amp area.
I know what you folks are thinking...... I just enjoy a challenge. Thanks in advance. John ab6li
