[Elecraft] K1 power out on 20m ... SUCCESS !

[David L DuPuy]

Don,

you pinpointed the problem exactly!  In the buffer stage, I'm afraid I
installed the wrong device for Q14 (really careless, to say the least).  I
pulled out the ZVN4424A, and replaced it with a new 2N4124, and I now have
power output on 20m.

However, I do still have a problem on 20m.  I did not have a clean sound on
the sidetone (sounded like heavy key clicks) on 40m before replacing Q14
today.  After replacing Q14 I now have a nasty sort of two-tone, worse
towards 5 watts out.  Sounds like an overload, or maybe RF getting in
somewhere.  I have the STL set way down to 1 or 2, and that controls the
volume, but the sidetone is still pretty awful.  In addition, I'm getting a
loud sidetone when I activate the TUNE function on 20m (not true on 40m).
Any ideas on this new problem?  Many, many thanks for your help.  David
