Logic operation:
A carrier with CTCSS of > 2 seconds from idle is required to latch the repeater. You can also use 1750Hz to open the repeater, once the repeater is open no further tones are required. Signals shorter than this will open the repeater but the repeater will close 250ms after the carrier drops.
Once the repeater has latched signals > 2 seconds will receive the unique “door open” beep. Signals without CTCSS will receive the lower pitch “door open” beep. The hangtime is 5 seconds in which time a carrier can open the repeater. The repeater sends its callsign every 13.3 minutes. There is a 5 minute timeout timer, the timeout counter is reset when the input signal clears. On every 30th tail drop the repeater send a close down ID at 680Hz.
