Alright well I guess it's my turn to ask as i've exhausted all of my ideas. Recently in the last 24 - 48 hours some sort of VHF interference has shown up on my sdr. It causes the noise floor to bounce up and down every couple of seconds by about 2-3 db. Nothing has changed in my office and i've shut down multiple devices trying to pinpoint the source and nothing has worked.
I'm wondering if anyone else has experienced such a thing. I've had solid interference before from LED lighting that i've since corrected and spikes but nothing in the form of an on - off wave like this. The darker blue at the top is after I shut the bias-t LNA off. The three brighter columns aren't related to this, I think they're FM interference even though i'm using an fm stop filter.
