Using a Nooelec SmarTee and getting these periodic wide band dips in signal strength (blue bars). I assume it's something wrong with my SDR. Is that a power issue or something?

hmm, 152MHz seems quite a long way out from 137MHz to cause issues, but if it’s very strong I guess that could the issue.

Yeah, the only reason I’m leaning towards it is because the typical periodicity and duration seems to match with my dropouts. I might try running an experiment with two SDRs tuned to the different frequencies to see if they line up.

Yeah, I was going to suggest that if you had a second SDR

137MHz is also quite close to the airband, sometimes nearby aircraft can cause overload

Oh that’s very interesting. We live right next to an airport! Planes flying around all the time.

I’ll have to take a look at that.

yeah, that might do it
