After some more toying around and reading, I think you’re right. There’s a periodic strong pager signal at 152Mhz that must be bleeding into my 148Mhz signal range a bit. I’ve already got a SAW filter that’s cutting it down substantially, so I don’t think it has much impact on the actual data.
Now to work on decoding that pager signal…
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
