[Elecraft] OT question about receiving loop antenna

[Alan - G4GNX]

May I suggest checking all your PSUs. I had the same issue once and it 
turned out to be the PSU running a tuner. I binned the PSU and installed 
a tried and tested new one. No more issues.

73,

>I have an RF Pro 1b receiving loop antenna which I use for diversity reception on my K3. It used to be sold by Pixel Technologies, and now it is handled by DX Engineering. If there is someone else who has this same antenna, please contact me off list.

I have replaced the preamp and I still have the problem. I am pretty certain that it is not an external signal, but I would like someone else to check theirs for the same issue as a sanity check.
