[Elecraft] FW: K3S filter Problem

[Bob DeHaney]

No Joy yet.  Two list members made suggestions, i.e. “Are the filters “ON”, yes, and perhaps mis-plugged, but I don’t see how that could happen and still fasten them to the board.  Anyone have another idea?  I hesitate to open the rig up, as I have the sub-rcvr installed and my 80 year old fingers have problems inserting the cursed TMP plugs.

I have installed an additional 400Hz and 200Hz Filter in my main receiver.  When I switch them in line, they both act as if open.  I see the signal on my P3 (strong Russian!!) but no audio.   I have configured them correctly I believe.  Could both be defective?  I have set gain at 4db and 6db respectively, no change.
