[Elecraft] K1 Filter Board Issue

[Don Wilhelm]

Jeremy,

Yes, an RF probe would be useful to evaluate the health of the crystal 
for 40 meters.
Since those crystals are reliable, I suspect that you have a problem 
with the Pre-Mixer Bandpass Filter.

You need to have at least 200mV peak to peak signal (70 mV measured with 
an RF Probe) to provide a good signal level to the mixers.

I am on vacation right now, so I do not have the schematics available 
right now to give you specific probe points,  I can give them Monday if 
you have trouble locating them.
