I am still not clear on the serial number when the CPU on the
AF-CNTL board was changed. I've tried to search for it but no
luck. And for that matter, what was wrong with the initial CPU. (I
admit I have not made that search.)
I just picked up an FT-847 and FC-20 that appear brand new. Radio
and tuner both did well in recent Field Day.
