Engineering FM – Part 1

This post is the first in a series of posts I’m going to do covering some of the engineering aspects of setting up a Community FM Radio station in the UK, and the lessons I and others learned while setting up the system.

First a bit of background. The station I helped set up, Insanity Radio, will be launching its FM transmissions in the coming weeks, and is a station run and operated entirely by students at Royal Holloway, University of London. The station started back in the 90s broadcasting on FM using a low-power rented transmitter, licensed under Restricted Service Licenses (RSLs) which only allowed for a week or two of broadcasting at a time. The station eventually moved to full-time AM operation, under a Low Power AM license.

Our license was awarded for a 25 watt EIRP mast to be installed on campus. So in 2009/2010 we got the ball rolling with planning. Continue reading Engineering FM – Part 1
