[Elecraft] Dead Sub Rcvr

[Jack Berry]

Could use some more troubleshooting help. I'm hoping to find a cable left 
disconnected but doubt it. Any tips on where to look greatly appreciated!

I added a few mods to my K3 last Friday & just getting around to running through 
all the features - shake down cruse. I find the sub receiver, which was working 
fine before is now silent expect for some odd spaced spurs in a couple of spots. 
It's the same on all bands checked. All else seems to be working well including 
the added components.

I had to pull the sub receiver while installng an AM filter in the main 
receiver, the KXV3 I/O module, KDVR3 recorder module, DSP board upgrade and 
installed KTCX03-1 temp controlled xtal oscillator.

I will open the case again tomorrow when I'm fresh and have time to go over my 
work carefully. 


Wish me luck and again, thanks for any advice.
