Buy a HD radio.

Seriously.

The Boston Acoustics Receptor HD, when tuning *analog* stations, seems
largely immune to IBOC QRM from *digital* stations on adjacent
frequencies. The set uses digital signal processing of analog signals;
I might guess that it uses the opposite digital sideband to cancel out
the one that's interfering with the desired analog station.

In general, my experience has been that the Receptor HD is a pretty
decent analog radio, both AM and FM, if you give it a decent antenna.
(the antennas provided with the radio are crap) Of course, it is pretty
expensive as well!

Of course, the problem for the radio industry is that almost nobody
*has* a Receptor HD - when the interference cranks up, people will buy
XM or Sirius, put in a CD, or turn on the TV long before they'll buy a
HD radio.
