[Elecraft] K1 #2500 QRV... almost...

[Rich Smith AB6TY]

Well. I just tested my 4-band K1, s/n 2500 on 30M and received a nice signal
report. :-)
 
:-(   But, I am having a problem with 20Meters. I am not able to hear a
signal at all on that band.  I did the ""Cheap and Dirty Signal Tracing for
the K1" having success with all of the test points except for numbers 4, 5,
& 6 which tells me that the problem must be in the KFL1-4 Premix Band-Pass
Filter section.  Anyone have an idea on what to try next to find the
problem??

Thanks
