The new Icom IC-92AD cost Your Price: $579.95 The current model IC-91AD cost Your Price $399.95 I want to know where the justification is for an extra 180 dollars? So far the only thing I can find is the 92 has the ability to use an optional hand-mic with a GPS receiver built in, and it can be dropped in water. Is there anything else the 92 can do that the 91 can't? I only need a dualband with dual-receive that does DSTARS. I just can't seem to find enough information to compare the two... Who owns these radios, what is your opinion?
