[Elecraft] K3 IF Attenuation?

[Dave C]

I've been using an AFEDRI SDR as a panadapter for my K3 for about a year
now using HDSDR.  I use it every day but when I powered things up
yesterday, the panadapter connection has suddenly experienced a lot of
attenuation.  I don't know at this point if the issue is in the K3 IF
output or the AFEDRI input.  The AFEDRI has adjustable RF gain and I can
still see the signals if I crank the RF gain to the max but I have lost on
the order of 20 dB in the IF connection.  (I normally run the AFEDRI with
about 20 dB of gain but I have to crank it up to 40 dB now to see the
signals from the K3).

I've tried rebooting things and checked the first layer of things like the
coax cable but I haven't found the cause of this big attenuation.  I went
into the K3 menu and toggled the KXV3 off and on but that didn't help
either.

Thought I would ask if anybody has experienced attenuation like this in the
K3's IF output.
