I did some www searching.. most of them, except the one that was being
threatened to be pitched out, seem to be in boats that are for sale or
for hire. Maybe it's an old reliable workhorse? I didn't mean to imply
that they are being decommissioned wholesale.

There is lots of room to work inside inside for the adventurous, but I
won't go as far as modifying a PLL or DDS circuit on this one. I have
some precision RF generators that could sub for VCXO's, and any
bandswitching control could be outboarded, but then it wouldn't be too
portable.

thank you,

It uses eprom programming.

This sounds like a good candidate for conversion using an additional
mcu; does the rig use DDS or PLL synthesis? How many stages of
conversion? If it is a routine discarded item, I must begin a
quest for some of these ;-)
