[Elecraft] K1 Receiver Issues

[Randall H. Sanborn]

I am completely new to amateur radio, the K1 is my first xcvr, and I 
don't even have my license yet.

I have recently completed the assembly of my K1 and I'm not able to pick 
anything up on the receiver. I worked with someone on the #hamradio 
channel at irc.freenode.net, and hopefully we've narrowed some things 
down. I will attempt to explain what we've looked at so far with my 
butchered lack of understanding.

I've tested all the toroids for continuity and they all check out, and 
I've also gone through the and filter baord portions of the voltage 
tables, and those check out as well.

With some quick and dirty signal tracing (30ft of wire with a probe on 
the end), I tried inputing rf into various points in the circuit. I got 
responses at the following points, all on the rf board:

U2 Pin 1
C38
X4, the leg connected to C38

I didn't get any response at the following points on the rf board:

C39
X1-X4 (except for X4 mentioned above)

Checked the voltages on D6-8 and they are all installed and working 
properly.

Any ideas where I should look next?
