Tom,

Actually, that's a good solution if you only care about hitting that one 
repeater.  You'd have to leave the TM-V71A in Remote mode, and you could 
store the DTMF sequences to turn crossband on and off in the DTMF memories 
of your TH-F6A.  I do that here, and it works quite well, so if you're 
interested, I can walk you through the process of setting it up.  The only 
issue that doesn't address is how to turn the radio off and disconnect the 
antenna during severe weather.  I probably shouldn't say this, but I never 
disconnect my dual-band antenna, and my radio is often on during all but the 
most severe storms.  Of course, now that I've said it, the lightning gods 
will kill everything in my shack just to teach me a lesson.

Steve
