I had another interesting experience in the car today. I was listening to ClassicFM (why do people put FM in a title, ffs?) on DAB. I had the car display up so could see when it switched to FM. Well, it did, but at such a tiny volume I could barely hear it. Next, after a few minutes, it switched to DAB again at a reasonable volume, but a few seconds later it was on FM at a much louder volume than the DAB.
Assuming those two FM transmissions were from different frequencies, as I can't think of any other reason the volume would change so much, we have the other problem. Why would two FM transmitters broadcast a station at different volumes?
I hope I am boring the numpties to death, by the way. Let them go back to twitface.
