In June 1970 Chris was the first person to locate the position of the government jamming station when it was moved to the former Battle of Britain Radar Station at Canewdon, Essex to begin its “Bong Bong” transmissions. Within days Chris had located it and notified the Radio Kaleidoscope team of its position. Buster quickly spread the word and a steady stream of radio supporters soon began arriving at the tiny Essex village.

Chris had used a simple Field Strength Meter (coil, diode & meter) attached to his bicycle to locate the Jammer, he then used the nearby GPO telephone box in Canewdon to pass on his findings. The AM transmissions from the Jamming site were so strong that they could be heard breaking into the telephone wires and dominating all of the telephone conversions.

The local people including Walter (Mac) McGowan were soon inundated with radio people congregating outside the two large gates of the former Marconi WWII Radar site, its large wooden tower supporting a MW antenna that connected to the newly installed government jamming transmitter, the compound perimeters were protected by large fences, inside was a large generator and the transmitting equipment.  Everything at this site represented the loss of all day music from the now very popular Pirate Radio Stations.

In later years Chris discovered that when the Canewdon Jamming transmitter was shut down. it was moved to Orfordness in Suffolk another old Radar site and home of the BBC world service and FCO communications.

Over the subsequent years the transmitter was gradually broken up for parts.
