[Elecraft] broken receiver, I suspect

I just sent the message below to support, but I suspect they are all
partying in Dayton. If anyone has any other ideas I'd love to hear them -
thanks! - jeff wk6i

hi - I recently lent my K3 #00027 as part of the W1AW/7 multi-op from
Nevada. The environment was not well controlled and I'm pretty sure my
receiver was damaged during a band change.

On the last day of the operation I was calling CQ on 12m and getting no
response. Turns out everyone was calling me but I was hearing almost
nothing.

On my bench I checked it using an XG2. The 50uV setting gave only S3.

I then did a full parameter initialization and then tried to calibrate the
RF gain using the K3 utility. The utility reported that there was not
enough signal to perform the calibration.

I also have an XG1 so I tried that. Same result.

I tried turning the pre-amp on and off, which did cause about a 2 S unit
difference as might be expected. The attenuator also caused an audible
difference but not a useful S meter reading.

One might suspect that I've blown out one or more of those PIN diodes
before the preamp. If I had any laying around I might try a swap, but...;)

Also: I do have the jumper for the extreme signal protection installed.
