THERE ARE 2 others but I have them at work, I'll try to remember them and get back to you. They're only used when the repeater is down. The freq.'s above are the 3 main freq.'s.
Yep, No pl's on APCO 25 transmissions BUT sometimes the repeaters are opened up with a quick PL burst upon a TX keyup, then latch open for the duration of the P25 transmission with no PL being broadcast by any station.
