The standard 136-174Mhz Mitrek configuration uses high
side injection, with a 10.7 MHz IF.
And remember, the 147.24 repeater will be listening
to 147.84, and the 145.21 repeater will be listening to
144.61 - with over 3mhz of RX to RX separation I don't
see a problem at all.
And if you are referring to the two repeaters being on
the same channel simultaneously, well, that's what
two different PL tones are for - set up repeater 1 on
tone A and repeater 2 on tone B.
Or am I not understanding the question?
