K1 - First station heard!

It did not take long to wind the last two transformers and run through the resistance and DC voltage checks on the RF Board. One thing I had noticed from some of the earlier resistance checks, and it happened again today, was that the results I got depended on which range I set my multimeter. For example, if the expected resistance were 1.5 kohm, then I would get an odd result if I set my meter to the 2 kohm range, but a correct result if I set it to 20 kohm or 200 kohm.

Anyway, I reached the point at which the manual says you can plug in a receive aerial and see what you can hear. I switched my doublet over from the FT-847 ATU to the K1 and switched to the 40m band. Success! I could hear a handful of QSOs in progress. Then I heard someone calling CQ: Fatos ZA1FD from Albania. Ironically, this would have been a new country for me, but I didn't have a key plugged in, and hadn't tested the K1 on transmit. Oh well, another time.
