FM transmitter for Tracker+ for low latency wireless audio?

Has anyone tried using an FM transmitter connected to the main line out of a Tracker+/Mini/Play+? Basically, I want to use the FM transmitter to wirelessly play back audio to my speaker system. This would be an alternative to using a Bluetooth transmitter which would have much greater latency.

As a reference, OP-1 Field has both a FM radio receiver and transmitter. And you can use the transmitted audio on any speaker system that has an FM receiver (OB-4 as an example). It’s a shame Tracker+ does not have a built in FM transmitter on top of the receiver. I am already using a Tracker+ with a USB battery pack, so an FM transmitter would be a great next step if we ever get a newer Tracker model.

Anyways, I was looking at these as compact examples:

If you do give this a try. Let us know how it went :blush:

Im interested in this too, there is mentioned following in the manual.

Im a bit confused about the aerial comment from the manual. If I connect a jack to aerial and insert the aerial cable to the data/signal socket in the wall, which is normally used for TV and Data, what would then happen?
