[Elecraft] K2 "not hearing"

[Gil Gibbs]

   I was going along fine on all my preliminary checks on my K2 
"revival", got the sidetone going OK, then started in on the secondary 
checks. To my dismay, I can't hear anything on any band, and I'm now 
wondering if I let the smoke out of something in the receive. Not being 
very good at tracing the schematic, I can't tell if the sidetone uses 
the same circuit to the headphone plug that the receiver does or not.
   Could I have fried a diode someplace, with that one problem of 
getting the KIO2 wires "backward" when I wasn't paying attention, in the 
course of setting up for the KAT100 addition?
    This is beginning to get old - I'm using dummy load more often than 
anything, and the SWL isn't a good result from all the hours. Any ideas, 
out there?

Tnx, 73's
