After searching this site I found 7,503 matching threads to high fidelity. I found 1,037 matching threads in the theatre forum.
I myself have asked many Hi-Fi related questions in that forum and have found the wealth of knowledge there amazing and very helpful. I’m sure your friend would find assistance in his quest for answers there.
The theater forum seems to be the best thread on this site for questions of this nature.Here in the intermission is also a good place too as the header says"The Intermission forum is for discussion of any topic not already covered by one of our many other boards " your enquiry isnt of a remote control nature and FM/radio recording isnt exactly a topic in the other boards.so someone might help your friend here too.Silly answers and jokes are usually posted here to questions that should have been posted in the appropriate board.
On a side note ... Over the years most sites have gone away from Hi-fi /only 2 channel forums. In the U.K. for example What Hi-Fi? Magazine (the most popular by sales Hi-Fi Mag) has become what Hi fi sound and vision magazine this is due to the massive uptake of AV but there are still many specialist sites and magazines.
This link might be useful but I would try this site first
