June 1983 - Radio Carousel, Navan. This is the AM Transmitter. It was located on the inside roof of The Navan Shopping Centre. Using 2 x 813 valves in the driver stage and 2 x 813 valves in the output stage, the transmitter was controlled by a crystal tuned to 1386 kilohertz. The valves needed to be changed every three months or so. They cost about £5 each and were imported from Russia. I had the job of getting a ladder and climbing up on to the roof to change the valves. I was actually scared of heights, but my enthusiasm of radio drive me to climb that ladder, conquer that fear and get the new valves installed.

As a matter of interest, the transmitter power plug was connected to a power socket in the Navan Shopping Centre. It was many years later before the shopping centre management found out that they had been paying for the power supply to the Radio Carousel transmitter without knowing it! It's not known if they insisted on back-payment after the discovery!
