Average Power from FM radio transmitters - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2010 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.

Dear All,

I was wondering how, in general terms, one might calculate the average power radiated from an FM radio broadcast transmitter. Now, most transmitters list their ERP (which is the peak power times the antenna gain), but I need to know what the average transmitted power is?

Bearing in mind that the FM radio band (88-108 MHz) contain many different broadcast channels within its 20 MHz bandwidth. So, the energy is probably not distributed eavenly across the band. How will this affect the average power calculation?

Suggestions will be gratefully appreciated.

Happy New Year to any of our Chinese colleagues who might be reading this.

Best Wishes

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.
