Morning Bill,
It never ceases to amaze me how receivers (and antennas) attract so much

Yes Vincens, you have to do all modifications implemented on page 52 !
But verifie that pin 16 of MC145170 is cut where you see the X on page 52 too !
As you said, it's for shaping the CW signal...

Boy, Kevin, you're right about conditions. The only stations I heard
were you (and you dissappeared for a while from about 00:20 to 00:30),
Tom N0SS (barely), N6JW (but so weakly I copied him as N6JA !) and
W7WEL, who was the only strong station.
Good thing I had a fully charged gel-cell power

I don't have the proper answer, but I can guess that a lot will depend on

I don't know the design details, but I have a good suspicion that the top

There are two solutions to the problem. One is exact, the other is
awfully close. For touching up the K1/K2 etc. color, Elecraft sells
small amounts of the exact matching color. If, however, you are
