[Elecraft] L1 & L2 Alignment Problem

[Don Wilhelm]

Carl,

There are many things that could cause the low output, but we do need some
additional information if we are to help rather than just guess.

First, did you hear a peak in tuning L1 and L2 on receive?  If you did, the
bandpass filter itself is not likely the problem.

Have you done the resistance checks?  How about the voltage checks?

Be aware that the most common problems are soldering and poorly tinned
toroid leads.  Examine the toroids carefully to be certain they are properly
soldered (use a magnifying glass - you should see solder adhering to both
the lead and the solder pad).  Then check all soldering, then check the
soldering and lastly, check soldering.

I've gotten to the point where I'm to align my K2 for 40M transmit.  When I
set the rig for 2 watts and hit the Tune button, as per the instructions,
the rig shows an output of 0.1 and adjustments to L1 and L2 make no
difference. I had originally thought that this was an indication that I had
overheated Q7 and Q8 in the initial installation.  I had installed them
backwards (not reading the instructions to bend them the opposite way as
Q6).  Therefore, I purchased replacements from Elecraft and installed new
finals.  Unfortunately, this was apparently not the problem, as I have the
same transmit problems during this 40M alignment phase.  Any advice on where
I should next look for a possible culprit?  Thanks for any and all
suggestions.
