If a transmitter is Certified in the first place it should not be creating spurs or harminics. OK lets look at MURS Radio service and FRS Radio’s which surly produce WAY MORE than a part 15 FM Transmitter. I think those little Walkie Talkie’s are 1 watt. Now I can’t remember the exact frequencies for FRS I use to know them and they were around 467 Mhz somewhere arund there. There is far greater chance for spurs and harmonics there. It’s really close to Police and Really close to public safety. MURS even worse. So with that in mind the FCC could enforce that all FM transmitters have a low bass filter in them or band pass filter. Anything above or below 88.1 to 107.9 MHz will not go through. Just like the little walkie talkie’s have blocks on them an FM and AM Transmitter can also have these filters. Technology has gone a long way. Especially overseas transmitters that come into here they can add a lot more to them and they are getting cleaner and cleaner every year. Its not a problem just in the US It is an issue all over the world and more and more documations is out there telling users how to filter their FM transmitters and which ones are more filtered. If your transmitter is only getting 1/4 mile a harmonic or spur would be half that distance.
The FCC is certainly gonna have lobbyests that will argue their points, but as an ex telemarketer you need to have those rebuttals ready. If your gonna petition you better have your ducks in a row even for AM because the same arguements will come to you guys too.
