FT530.2

I have a comment on the FT530 mod.  Near the end of the instructions there
is a warning not to transmit out of band; maybe a comment should be added to
remind users that the FT530 can store a separate transmit frequency (not just
an offset). I did this for the items I stored in memory, that were in the
extended transmit range. This way if I ever make a mistake, I transmit on a
HAM frequency, not the public service freq I was listening to..
