AM is always better for checking out your man-made 50HZ/60Hz noise floor. I have been chasing noise around my QTH for a long time now. It's pretty bad, as my videos show! 73.

How did you get the idea, that noise would be present at 1.8-2.0Mhz?
This must be a hit and trial method.
You must have put a RF choke in the main line to prevent this interference from happening.

Yes, I put a AC Line Noise filter on the Switch Mode Power Supply AC cable. That stopped 99% of the noise.

What is that instrument that you have?
It is the amateur radio transceiver Icom IC-756pro3. It has a spectrum scope for monitoring up to +/- 100kHz from the receiver frequency.
