Re: some simulcast questions

Does injecting instead of CTCSS, using DCS or digital squelch.
What about instead using P25 or a DMR variant??
I agree with others, those Quantar's should stay in service. Decent machines. We run a UHF P25 system conventional to cover 3 counties (on handheld) and have toyed with a 2 or 3 site voter/simulcast system. Costs are my concern for the amount of needed coverage, considering mobile repeaters instead. - -

One of the old simulcast solutions would be to have a master CTCSS
oscillator at the control point and send the tone to all the transmit
sites.? If you used RF links and they had flat audio response, the CTCSS
tone could be included with the receiver audio.
Here's a thought.? If the individual transmitters were synced to a GPS
source, and the individual CTCSS oscillators at each transmitter
developed the tone from the same oscillator source, this may be a
solution to the CTCSS problem.? Some accommodation would have to be made
for CTCSS audio delay.
Thoughts?
