I'm getting ready to do a presentation on XBR to our local club.. found this thread.. thought I would add my 2 cents.
the easiest way around the id rules, is don't do a two way crossband!! depending on the capabilities of your radio, there are 3 ways to accomplish this...
Split PL's
Illegal TX freq
2m offset.
example repeater: 147.260+ with 100hz pl on tx and RX
split pl's works with an ICom 2800, and an Alinco DR635, but not a Yeasu FT8900 (radios Ive owned)
but it works like this:
HT: listen on 147.260 with 100h pl (repeater output) transmits on 445.500 with 123hz pl
Mobile: 440 side is set up simplex 445.500 with 123 hz pl. 2m side is setup for 147.860 simples with 132hz pl DEcide, and
100hz ENcode. this way, repeater output is not relayed, and should someone else be near by your mobile, their 2m tx won't key it up.
illegal TX:
HT: listen on 147.260 with 100h pl (repeater output) transmits on 445.500 with 123hz pl
Mobile: 445.500 123hz Rx, 451.000 TX. (illegal tx, won't tx if you are limited to ham freqs) 2m side: 147.860 100hz simplex.
2m offset:
HT: listen on 147.260 with 100h pl (repeater output) transmits on 445.500 with 123h pl
mobile: 445.000 123hz simplex. 2m: 147.860 100hz tx. 147.760 rx (132pl) (just make sure it's an empty freq, and use odd ball PL or DCS just to be sure)
I use the illegal tx option with my FT8900 and split PL's with my DR635
