53.470 MHz -1 Mhz PL 100.0 Hz - GE Mastr II 100 watt

COURTESY TONE DESCRIPTIONS (see notes below)
port 1 - 444.525 - 1200hz courtesy tone - single beep unless 10m port enabled (see notes)
port 2 - 53.470 - 800hz courtesy tone - single beep
port 3 - 29.600 - 400hz courtesy tone – single beep

Notes: When 10m remote base (port 3) is active but in “receive only mode” repeater users will hear cw “R” (dit-da-dit) which is heard only when you key repeater.

This mode permits repeater users to have QSO on repeaters while listening for band opening on 29.60 FM without transmitting over 10m band

When 10 meter remote base is in transmit mode - repeater users will hear a “distinctive” single dual tone courtesy beep after repeater key up to indicate remote base tx is enabled
