KFMD Technical Information

_____

Below is some basic background about the classification of this type of radio station.

In addition to the internet stream which is currently running, we broadcast with a Chez Radio Procaster transmitter over the air on AM 1580 in Fort Madison.  Below is some important information to help the general public better understand the legal aspect of unlicensed AM broadcasting in the United States.

KFMD operates with a Class B device. It is classified as an Intentional Radiator.  Consumer electronics such as our transmitter are very low-powered and subject to less demanding use compared to licensed broadcasters.  Class B devices have less stringent requirements governing internal protection and also EMI tolerance.  Residential devices that Class B covers are designed to have lower power levels. This insures they won’t cause disruptions to the owner or their neighbors.   This station's transmittter could be classified as a very expensive AM version of Mr. Microphone.  

There are thousands of these Part 15 Radio Stations operating in some form all over the United States.  Some are commercial broadcasters while others are operated as professional non profit entities or others by hobbyists and radio broadcast enthusiasts.  The link below will take you to a website listing dozens of these Part 15 stations around the country.
