With today’s radios, FM sounds the best. Manufacturers put most of their efforts into the FM receiver, with AM being an afterthought. But, license-free operation limits your transmission distance severely.
You do have to be very careful on FM because both the licensed broadcasters and the FCC are on the lookout for illegal operations. There’s a thread on the Ramsey Electronics forum about a guy who’s running a legal Part-15 FM, and a licensed operation 35 miles away has threatened to report him unless he shuts down.
Given today’s climate, if you can run AM, do it. You’ll sleep at night.
