FM Free Radio / Legality of broadcating on 87.9 MHz
« on: October 18, 2017, 2248 UTC »
I've been reading some FCC notices of violations, fines, etc. that they've issued to people. I noticed that some had been busted for using 87.9 MHz, and that they exceeded the limit of 100mV/meter as measured 3 meters from the antenna. On the standard FM band (88-108 MHz), they have a limit of 250 microvolts per meter measured 3m from antenna. For comparision, 100mV per meter is a lot more than 250 microvolts, which equates to 100,000 microvolts. Does anyone know what power wattage this would equate to?
In laymen's terms, it sounds like we're allowed to use a lot more power on 87.9 than we are the rest of the FM band. Could someone elaborate on this?
