H.L.R used many sites around Hertford to broadcast from. Most of the sites were wooded areas where the aerial would be mounted near the top of a tree and the transmitter would be at the base powered from a car battery.
Sometimes peoples houses were used but generally only for short periods over christmas or other bank holidays.
One particular christmas the transmitter was based upon the top of a government building near the center of Hertford. At the time the building was incased in scaffolding which was climbed to access the roof.
