Re: Interfacing a Consolette to a quantar RT/RT

If you are going to go to that complexity why not used licence free 900 MHz Ubiquity? Sure the 800 MHz mobiles might have more power but you'll need to crank them down a long way to get any life out them. Mobiles just are not designed for 100% transmit duty cycle.

If you program the repeater for mixed mode and make an analog connection as well between the machines then yes. To be clear the digital connection doesn't carry analog and vice verse. There is no codec function in the Quantar.
