Some hts will cross band and many dual band mobiles will. Most of the
older icoms and I think some of the newer kenwoods, but I haven't kept up
on latest models of 2m 440 radios. It is legal. I use to do it all the
time. Main thing is to get a radio with a voice synthesizer. The icoms
were really cool, you could issue a command and the thing would reverse
itself and send you the frequency it was on with the synthesizer.
