Yeah, it's not a bad receiver in general -- just a case of that
connector *potentially* being a source of headaches.

Oh, that's good then -- I'm in an area where it's "oh if you wanna
listen to THAT station, the radio has to be THERE; but if you want THIS
station, it has to be HERE"

Granted it's just some old boombox (probably from the 90s) that's seen
better days.

The selection of tuner chip(s) is what gives the possibility of wide
input range -- in this case the R820T, which runs from ~40 MHz to ~1000
MHz; allowing it to receive basically all globally-transmitted VHF and
UHF television signals (here in the US, they're broadcast roughly
between 50 and 800 MHz).  It's not all that special of a tuner, in the
sense that televisions have used something like this for probably 40+
years now; basically ever since you had to stop worrying about whether
to tune VHF or UHF to get what you wanted to watch.

Tuner works for "radio" simply because FM broadcasts (88-108 MHz in the
US) are between the former VHF stations 6 (87.75 MHz) and 7 (177 MHz);
though I think those have been long decommissioned in the US (2005? '08?
something like that).
