In the radio field, FM stands for 'Frequency Modulation'.

Your question is entirely too ambiguous. What made you think this? What was the reasoning for your choice of modulation technique? Example you said FM. Why? Not to be nasty but it appears to me you do not know what FM means. If you think it is the FM broadcast band OK but FM is Frequency Modulation. AM is the same but using Amplitude Modulation. There are many other forms of modulation and they can be used on any radio frequency you can generate. However there are laws requiring various techniques on certain frequency to keep form causing interference. FM does not mean anything about frequency. Most people think of FM as the FM radio broadcast. Nope FM is a method. So why did you think this? Was it due to your FM radio in the car? If so,,,,, you bet I could talk to you on it. I would however need to know the frequency you are tuned to. Or in another form "what station are you tuned to? See how ambiguous your question is?

Alias for 1,1,1,2,3,3,3-Heptafluoropropane
Actually, AM is better than FM. AM can cover the world, and is the best form of communication. FM is completely worthless except for the fact that it's better sounding.
Answers to FM body of knowledge assessment?
FM broadcasting is a broadcast technology invented by Edwin Armstrong that used Frequency Modulation (FM) to provide high fidelity sound over broadcast radio
