[Elecraft] K2 problem, troubleshooting (alignment and signal tracing)

[Jason Marten]

Ok, here's an update.

I raised the HI CUR limit to 3.0 Amps, and haven't seen a HI CUR warning 
(except sometimes when power is set to 15 Watts).  I went through the Part 
III Transmitter alignment, and was able to peak all of the L's and C's 
without getting any HI CUR messages.

As a side note, I also measured my random wire antenna's length, and it was 
pretty darn close to half a wavelength at 20 meters.  So, I cut a few feet 
from it.  Haven't noticed any thumping on the TV anymore, tho I notice a 
very slight amount of TVI on channels 3 and 4 (I have cable).  On other 
channels, I can't see any effects.  This is with a low pass filter between 
the K2 and my LDG Z-11 tuner.

I also tried using my MFJ-259B as a signal generator to continue on with the 
BPF test with the RF probe.  I was able to get some values above 0 Vrms, but 
the MFJ is so unstable I couldn't get any good readings.  But at least it 
verified things were getting through.  Of course, I was able to listen to a 
few QSO's on CW and PSK31 as well (like before) so I knew things were 
working.

So, I think I was probably pretty good all along, I just needed to raise the 
HI CUR limit a bit.  Thanks for all your time and help.
