Nice sleuthing work, Scott. I noticed another issue with the KXV3. One
of the first things I did with my finished K3 kit was to look at the IF
output prior to connecting it to my panadapter project. I was mainly

I think it depends on the noise source. If it comes from one
direction, a loop antenna can be rotated to place its null on the
noise source, improving the signal to noise ratio for the signals
coming from other directions.
On the other hand, if your noise is more pervasive, and turning
