Hello to the group.
I am building a 3 channel voting system for a local repeater group
and I was wondering what the rest of the world is using as a
interface for the voting reciever/transmitter package. How are you
configuring your pl? I have built up some MVPs and that part was a
slam dunk.
Hi John,
I doubt that the problem lies in the controller, but rather your
'modulator' isn't flat. If you scope the audio path, you should be able
to make sure that you don't have excessive roll-off or distortion in the
audio chain.
My suggestion is to change the exciter to provide True FM.
Does this mean that this vintage of the Q-202G's are only capable of working
at one insertion loss point for any given offset?

Rotating the loop would change the insertion loss and the pass to
reject spacing.

As someone already pointed out, the PL tones are weird
frequencies so they're not harmonically related. DTMF
tones are similarly set at odd frequencies. DPL/DCS

the same reason, so repeating bit patterns aren't
falsely decoded. Paging tones
