squelch mode

[nanderer]

Please implement a squelch mode so i dont have to here the noise while noone is talking.

Thanks a lot in advance

What modulation is this using, i tried it using a PMR446 radio, i was able to recognise that there is being something but wasnt able to make out a single word. Do you support narrow FM or what are you using? It would be also grate to have a more fine frequency settings and save a couple of channels to scan through or just listen to, of cause with a squelch mode ;)
