[Elecraft] K2 Deaf

[Rob Gault]

Initial receiver testing on 40 Meters (pg 67) can barely hear XG2/XG3 @
50uV.  I've injected the 50uV from the XG2 directly to the input of the
rcv. mixer Z6 @ R73, no change.  VFO Input to the receive mixer looks good
on a scope, no IF signal to be found at pin 1 of J12.  Q22 voltages
nominal.

I've eyeballed all solder connections and Caps and Resistors and confirmed
values.

We have confirmed the injection and testing procedure on a known good K2,
lots of IF signal at J12 pin 1.

Looks like Z6 is the problem?  Any other ideas or thoughts?
