RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

FM Band Transmitter Specs - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

Sorry for posting in multiple places, but I need this in a hurry.

Does anyone know exactly what FCC spec governs the output of an FM transmitter? My application is for low power (<1 W), and in fact will be covered by Part 15. However, I want to know the real specification limits for THD, frequency accuracy, L-R channel separation, S/N, etc.

I have spent a couple hours searching the web and the FCC website but CANNOT find it!!! :(

Thanks a lot guys (and gals, if applicable :wink: ).

I believe this is what you're looking for.

Radio and Television Broadcast Rules 47 CFR Part 73

Look in Subpart B.

Good luck.
