Any OG Cap artists know wtf this noise interference is? I've got everything through AVR Sinewave UPS (for dirty power).. LD or VHS, changed rooms, cap cards, between laptop/desktop, turned all powered devices off.. its all the same. What the hell is doing this? 

Have you ruled out ground loops? I had to make sure both my capture PC and the playback device weren't powered by a grounded power cable in order to elminate ground hum.

The UPS AVR online Sinewave unit has a ground wire (3 prong). Where else do I look? And how do I check for it?

Is it possible for you to try a location change?

I can but I am not able to lug that 60+ pound extra large unit around to someplace like Starbucks or a hotel

Do you get the same thing without the UPS?

The only reason I ask is to remove potential interference introduced from neighbours.
I knew someone who worked at a recording studio and had they had to move premises because a neighbour ran industrial freezers 24/7 that caused pops in recordings when they kicked in.
This was 25 years ago, but I imagine It can still be a thing.

Yours looks like a regular pattern though!

I've had this issue for a long time before the UPS. I've only had the UPS for a couple days now. I got the UPS hoping it would fix the dirty power issue (assuming that was the cause)

interesting, I will see about maybe loading everything up, going battery powered, and trying a cap at a park or something

Saw you tried different cap cards, did you try another set of other cables too?
