Do they decode PL properly from anything other than your repeater? (Simplex -- have someone transmit on the output with the right tone so they're not changing channels, in case they programmed the rigs wrong.) > I have the PL Deveation set at 1K.

Many radios I've tested with will open consistently as low as 300, but for "most" rigs to decode, 650 seems a good compromise. Maybe you're flat-topping something in the PL-generation circuit and the newer rigs are looking for the whole waveform instead of zero-crossings. Have you looked at it on a scope? I'd start with proving their radios work correctly on the programmed channel for your repeater first. Nate WY0X
