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.

Yeah, that much I figured. I was just wondering what range of
frequencies they use.It's outside of the regular FM band, and I suspect
its up around 800-900 or so since it must be a part 15 device. It could
also be around 433. I'm not sure where these things are licensed... Pete
