Welcome to a Saturday Morning Radio Cartoon!
Barney Bear in "Wild Honey" (1942, MGM)
Barney Bear is looking for wild honey with the aid of a high tech "bee detector"
It's a large box like desktop shortwave radio of the day, with labeled controls and a meter reading up to 5KV. The innards of the detector is full of tubes resembles the inside of a transmitter.
When a bee flies down the horn and gets into the works, the fun begins.
The first part pretty much covers this part of the story. Sorry the youtube quality is poor, but it can be bought through proper channels.
