I did a google search, and apparently the 7200 can be modified for MARS, but what I found describes not only removing diodes, but adding diodes.
So I've got to ask, is this radio something that's fairly straightforward to modify, like my 706mk2g was, or is it something that I should seriously consider having ICOM or someone else do it?
Thanks,
