It does not pass through the transmitter, it's the beat note in the overlap areas.

The Quitron/Glenayre system I worked on had over 100 transmitters and some of the overlap areas had 3-4 transmitters illuminating the same area. If I were to build a system that only had, maybe 4 or 5 transmitters, I would use 20HZ. I don't see how 20HZ would get thru the audio circuit of a transceiver. Too close, such as 2 to 6 cycles, would up the chance of two transmitters drifting exactly on the same frequency. (You don't want this). 20HZ would be better, in my opinion, on a small system, more room for frequency drift without zero beat occurring. An interesting side effect of 20HZ would be that, if the tone became audible, it's an automatic indicator of maintenance being needed because a transmitter drifted off the 20HZ offset. Hearing the simulcast offset tone would be no different than hearing a little PL tone leak through. It would also indicate that you are in a simulcast area. 73, Joe, k1ike ---- Paul Finch <[EMAIL PROTECTED]> wrote: > FYI, > Quintron's offsets ran 2 to 6 cycles per transmitter at the most. 20 > cycles > if getting audible.
