It now supports both analog FM as it always has, along with P25 digital voice, in keeping with our 146.64 and 927.1375 repeaters.

For those with P25-capable radios, the NAC is 075. Please configure your radio for mixed-mode receive.

[Edit: It is 075 hexadecimal, which is the standard way NACs are expressed. I had erroneously indicated it was 075 decimal previously.]

For those with analog radios, if you are hearing the buzzing noise of P25 users, you should ensure your radio is set up for tone squelch on receive (88.5 Hz, same for transmit and receive). Please look at your S-meter or momentarily listen in carrier squelch mode before starting a QSO, to ensure one is not already taking place in P25.

Two cabinets consisting of four amateur radio repeaters.
The club’s four repeaters. On left, 146.64 (top), 224.94 (bottom), and APRS digipeater. On right, 927.1375 (top) and 449.075 (bottom). The pill bottles contain peppermint oil to deter mice, a common repeater site pest.
