Well, since I have multiple threads going, I'm not sure where to post this. I got the SDR configured with RTLSDR scanner and found a surprise, but not a good one. It's a land mobile radio service on the same tower. Note, the FM stations are attenuated by 2 filters and a small amplifier is inline. I think I have to rethink my high pass filter. The calculated cutoff is 160MHz. I'm also including the FM band with no filters for comparison.
