Nice little AM transmitter.
For those of us in the record player collector realm (I probably have 75 record players) Chris Cuff is a bit of a legend. He's a go to guy when you have a restoration question and he also does restorations for others. He designed this as a transmitter to hide inside a 1950's era RCA 45 RPM record player that did not include a built in amp or speaker. (You plugged it into a radio for the audio) and by including this little transmitter you could play records wirelessly. Of course to do this you also have to convert the record player to a stereo cartridge, etc, or else you could just use a mono transmitter.
Some of you may find this playlist amusing.
Unfortunately Chris has suffered some serious health issues and has spend much of the last couple months in the hospital. But a real asset to the record player collector community and a great guy.

That was great. Never saw a record player that worked like a CD player that you could carry around.
