DMR does this, but its natively designed that way. Analog would have to issue a time delay that shifts just as long as the "record" increment. The down side to this is it would then create an "echo", or even something that sound like multipath propagation to those already in range of the initial transmitter. It's going to be an expensive venture without desired results.Hi all,
I've just had a thought !
When transmitting, then on the switcher will be only switched to transmission, on this radio.
When receiving, in order to relay, it will need to capture, a 50% section of the received voice, then transmit it in 50% time, then back to receive.
Less than 50% of the voice relayed isn't perhaps good enough.
The other thing besides switching speed, is how fast can the transmitter power up to relay the message, as you will loose time in that warm up as well. I would also question how fast you will burn out the radio, even if it was only 4 cycles a second, that's a lot of on/off switching and potentially a lot of wear on the electronics.
It really sounds like you need to either get on a real repeater, or continue relaying traffic between each other. You could also look to using echolink or other internet connectivity protocols, but to keep it simplex, and reach all involved, you all need your antennas higher to maintain a true line of site. Even 10' higher for each of you would significantly increase the range.
