unless... the cell tower is somehow causing the lower freq. noise - maybe drawing on a power supply or something

... the frequency my stereo is picking up is in the 700 - 800MHz range.James, check out this link:
The band extending from 698 to 806 MHz is used by public safety services, with part of it also apparently being used in some locations for cellphone or other mobile device communications.
Hope that helps. Regards,
@almarg Terrific find. That would explain why some days it’s quiet, and other days it’s busy. Early mornings 4am to about 11am it’s quiet most days. And it goes on late into the evenings. Yesterday it was very busy all day long.
I also used the Hf35c Rf Analyzer to walk around my apartment with all the power turned off, to find quiet zones, unfortunately I do not have much flexibility in my room arrangement for the system. It’s called living in a shoebox.
I’m not too bad off, the noise is a low level noise, just-at-the-natural-noise-floor of the room. Its traffic outside, people, cars, bikes, skateboarders, road construction, building construction, air planes above, I hear quite a bit.
I have a police station down the street, and a fire station a block down, so I hear a lot of sirens, which may also contribute to the public safety band Al had mentioned above. So between the subway, the cops, and the firemen, my stereo should keep me in the loop.

By chance does the Analyzer have the ability to indicate signal strength as well? If so walk around your apartment and see where the signal is the strongest.
Next go out the entrance door of your apartment to the central House hallway, corridor, of the floor you are on. Walk the hall in both directions and check for a hot spot in signal strength. Point the device at both walls on each side as well as the ceiling as you walk down the hallway.
