Radio Caroline 648 kHz power increase

The opportunity arose to boost our power on 648 AM. This was beyond the ability of the existing Nautel machine. High power AM transmitters are not easily sourced now. We found one in storage near the Dutch/German border and imported it to Essex so that it could be very extensively overhauled and converted. This was a long, costly and labour intensive task. Then the Harris DX25 was shipped to Orfordness and delivered by landing craft.

The staff of Cobra Mist, who could have left us to struggle, were particularly helpful. Our unsung heroes were Howard Beer, Alan Beech and Steve Bradley. Working conditions veered between not very nice to evil.

Now the new transmitter is in service covering, we hope, a much larger area than before to reconnect with more of our listeners from the past. Obviously we would like to know where our signal is going and indeed where it is not. Might you help us with a reception report so that we can see what we have achieved and to consider what we may do next.

Harris DX 25U Transmitter

Two views of our new transmitter part way through its rebuild. The Harris DX 25U is a 100% solid state unit with digital Amplitude Modulation. Harris DX transmitters boast a typical efficiency of over 83%, resulting in the industry's lowest power cost. They also contain a lightning protection system and broadband interchangeable RF amplifier modules to simplify remote maintenance
