Broadcast Bands?
#4

The police band on these old set haven't been used by the police since before wwII. Nowadays it's all vhf and uhf fm. LW band is pretty useless short of a small ham band and a couple of navigational signals that are transmitted in Morse code. Bands that have Amateur markings still are ham bands and since the 80's a few more have been added.
These days there are a lot of modern devices that generate a lot of interference in the lw/mw/sw bands. Phone and laptop chargers are some of the worst offenders. They use what known as switch mode power supplies. They make buzzy noises all over the spectrum.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
