Hello to the list... Anybody know of a source for the internal power supply for the MP to upgrade it from DC-only into an AC unit? I may need several of them. And, the basic question....how much? $ or $$ or $$$$? Yaesu USA told me it would be the FP27 at $445 but that sounds a bit high to me...and I'm not sure if FP27 is the PSU I need. Tnx for any help. 73, Esa w5/oh7wv
