I saw a disciplined oscillator using cdma cellular instead of gps - This would be useful in synchronizing transmitter oscillators. Ed O Conner at Simulcast Solutions has been a super helpful resource.
The other half of the picture would be site voting receivers... Most ham clubs do not have the resources for a simulcast system, but it would be nice. Also a trunked 2 or 3 channel system could be viable.

Remember -frequency-phase and deviation from each transmitter is very important. Regards Bradley Glen ZS5WT --- Steve Rodgers <[EMAIL PROTECTED]> wrote: > > Thanks for all the replies.
