Some of you may remember my problem with the KPA100 not being recognized by the K2 after a little mishap I had.
On the sound advice of a few on this list, I purchased a new 78L05 (U3), EL5146 (U6) and a MAX1406 (U4). I just swapped all of these out, and am getting 5V in places I should now. Probably U6 was bad. The K2 is still giving me a NO PA PS message with a PS plugged into the KPA100. In fact, it's the ONLY PS plugged in. The menu gives me an E12 and an F1.10 whatever that is. I did some measurements, and U1 is ok *except* for these: Pin 7: .8v (Book says 4V with note 2, depends on PS voltage) Pin 10: 2.25v (book says 2.4v, seems a *little* fishy?) Pins 12, 13, 14: all 0.0v, book says 0.5V Pin 26: 5v. Book says 0v?? I checked it 3 times to see if I counted wrong, but nope, that's the pin. So my question... is U1 bad, or is something that's feeding U1 bad?? Could it be something on the K2 control board? Any ideas appreciated! -Chris KL9A _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
