This is defeatable, I have described this several times - instead of
turning off the tone generator thereby activating the reverse burst just
use a hold low in between 2 15K resistors to pinch the pl output of the

Sounds like you had the wrong Motorola tuning tool ... :(

The best thing you can do it use real repeater equipment like a Motorola Micor
or GE Mastr II. Trying to make that Icom equipment work is going to be a
pain. Use it for a mobile like it was intended to be.

Yes, it can be done as long as the frequencies are far enough apart. We used
some TX/RX duplexers to put two 2 watt security transmitters on the two
frequencies of a repeater pair into the same 450 antenna. This was done to send
