This is probably considered a cross post violation, but I'll take a shot.

Is anyone familiar with this area (85929 zip code) and if there is a high powered transmitter that could be overloading my SDR scanner setup?

This is a video of what I'm getting:


It is a Nooelec Nesdr v5 dongle, fed by a Sirio GP 3-E antenna tuned to about 150MHz, on the roof of a metal building, connected with 30ft of LMR400 cable.

I'm not savvy with filters and attenuators so if that's a possibility - please explain it to me like I'm a 10 year old.

If I connect my Tidradio TD-H3 Ham handheld radio to the antenna, everything is fine, I can hear everything clearly.

I appreciate any and all help.
