GE Master II Configuration
Two versions of the GE Master II Repeater Control Panel exist. The "
earlier
" version is
identified by multiple plug-in cards, the 10 volt regulator card being on the far right. The
"
later
" version is a single panel (no plug-in cards), and is identified by the local mic
connector, speaker, and volume knob on the front. All connections are the same except for
the TX Audio. On the later models, TX Audio is connected to the "Battery Alarm Audio"
point. Follow these steps:
1. Remove the jumper between H16 and H17 (if installed) on the 10 volt regulator card.
2. Discriminator audio may be connected to Volume Squelch Hi (J932, pin 3).
3. Remove any existing repeater tone panel (card-per-tone), and "Repeater Audio" and/or
"Repeater Control" cards (if installed).
