I picked up one of those last year...and I asked the same question on
one of these newsgroups shortly after the show too.

I found out that they are FM radio scanners. The company that sells them
runs low power transmitters at the event rebroadcasting the tower, or
car at NASCAR events. You can replace the battery and use it at OSH next
year, as long as the company comes back. Other than that, you've got a
FM receiver to hang on your ear.

The key to finding out the information was to open it up and get the
specs on the circuit in there, where I found it was the FM scanner.

I picked up one of these cool radios, but it didn't work well in Camp
Scholler.It worked ok on the flight line though. Does anyone know what
frequency these things work on?
Give us a brand and model number, so we can have a clue.

Most likely, you got a relatively cheap scanner, that picks up either

Actually, I think he may be talking about those cheap-ass radios ($5?)
they sold so you could listen to the "EAA Radio" or whatever it was
called.

Not too surprisingly, it was sold for that one and only purpose, and
that's the one and only thing it was good for.
