Default FM radio interference from planes

I discovered, once I started using an FM transmitter with my MP3 player in
the car, that once my FM transmitter is turned off, the car radio will
pick
up the ATIS broadcast on the frequency I'm using for the FM transmitter
(107.3...but I doubt it matters much).

Hmm...inquiring minds want to know...is the ATIS around 128.7-128.9
'ish???


As a matter of fact: 128.65

I guess that's "around" 128.7

I should mention that this particular car radio is highly susceptible to
radio interference generally. Down at the lower end of the "dial", say
93.3-ish and below, it's quite common for me to get interference from cell
phone towers. Or, at least it's my presumption that it's cell phone towers,
since they are pretty much the only ubiquitous kind of RF interference that
I know of.

When the interference happens, whatever I'm listening to turns to
high-volume static, without any intelligible signal at all. It practically
never occurs while I'm standing still, so presumably I'm moving into
interference range and then back out (the interference generally lasts
between 30 seconds and a few minutes, depending on how fast the car is
moving and whether I get stuck at a light ). And it never happens on the
higher frequencies (when I do get static, I can just switch to a
higher-frequency station and everything is fine there).
