Oleg, you'll be my hero forever if you can do this:

Way back, when I was in flight school, we had to fly a set number of hours in C-172RG's. It took no time at all to become proficient in the required maneuvers, so I became fond of climbing above the mayhem that was our practice area, tuning in an oldies station that played big band music on the ADF, and swinging that fat old Cessna around the sky in time to Tommy Dorsey and Glenn Miller while the setting sun turned the Oklahoma summer haze to gold. Good times man, good times.

So I was thinking it would be maximum cool if we could tune the DF (in aircraft so equipped) to commercial broadcast and get period music, news, speeches, etc. It would be sooo cool if an announcer would break in to announce air raids as they happened. It would be extra very cool if what was on the radio was what was actually playing on that date and time. It would rock to tune in and catch Churchill addressing the nation, or hear ol' grumpypants himself working himself into a lather. German stations playing Lil' Marlene... Burma Shave commercials...
Immersion, anyone?
