Average Power from FM radio transmitters - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the 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
RF Burns
