Full Channel Digital FM Transmitter FMTF (Bedford MK43)

This is a Macally transmitter for an iPod or MP3 player to be streamed in a car.
I remember now how we used it and Chatgpt confirms it is still a good way to stream music in vehicles without Bluetooth.

The Macally Full Channel Digital FM Transmitter (FMTF) niche use case is
"Car Audio: If you have an older car with a radio that doesn’t support Bluetooth, an FM transmitter like the Macally FMTF could still be useful for playing music from a phone or MP3 player through the car’s stereo system. However, newer Bluetooth FM transmitters (with better sound quality) might be a better option.

Broadcasting to an FM Radio in a Limited Area: Some people still use FM transmitters to broadcast their own content (like podcasts or music mixes) to nearby radios, such as for personal radio stations, hobby projects, or events."

I could deliver to villages around MK43, to Poets area, Clapham, Brickhill and Goldington Road when I come into Bedford if that helps.
