What's the point of the two vfo's? I'm trying to figure out how the crossband repeater works. It listens on two separate input channels (2m and 440) and sends on two separate output channels (440 and 2m)? So someone with a 2m HT can talk to someone else with a 440 ht, but two 2m users can't talk to each other?

Is it really that useful? Would you set it up on a hilltop (tall building etc.) to provide repeater coverage to some local area or what? How would you power it, and how would you keep it secure? Actually I guess just putting it inside a car (roof mount antenna) would be a big help in letting HT users talk to each other. But I think a traditional repeater, or crossband mobile rig, makes more sense than an HT for this purpose.
