[Elecraft] K3 kit problem

[Dave Hachadorian]

Just finished building K3 sn 1176. When I went to do the 
reference oscillator calibration by zero-beating with WWV, I 
found that the receiver is deaf. Even with a large antenna 
connected, there is no increase in background noise, and no 
signals can be heard.

When I turned the K3 off and then on again, it came up with 
ERR IO1. Scary stuff. Any suggestions?

Thanks.
