Hi,
Does anybody in group know the frequncy tolerance of generated audio
tones used in two tone sequential paging? I know one can get away with
+/- 1hz on PL encoding and it will generally still work.

I keep hearing about this better data from commercial propagation

A lot of the original 30

Pretty loose, I'd say about +- 1% would still work.
Thats about all the tolerance they could get with mass

Your training and preference are great for hi-fi audio
equipment, but repeaters are optimized for weak
signals with voice only, and as such, fidelity is not
one of their strong points. 50 - 3500 Hz is about the
limit, and the user radios will make it sound even
worse.
