Strangely enough, most of us wanted to expand the transmission range -
especially those in Oz etc where they can transmitted way outside our limits.
There is software available from Elecraft on request to do that (for MARS).

The synth won't usually tune that low without a modification, and the
modification would make the synth not function correctly on the other

Not to beat a dead horse... I don't think this is an issue of trust, our

If you use DX Lab Commander to change bands and then return the same

I suspect there's a larger market there than you might think, at that
