James Loughlin was the OFCOM UK Accreditation Service (UKAS) Technical Manager before he retired in April 2017.
A very good turnout of members and visitors enjoyed James history of Baldock Radio Monitoring Station.
Initially (around 1930) the station received Transatlantic radio telephony signals from New Jersey USA, and continued to use HF bands to monitor international Radio Circuits operated by the GPO.
The station is now called the OFCOM Baldock Radio Monitoring Station and the frequency range covered is 9 kHz to 3 GHz.
On receiving complaints of interference, the station can deploy remote monitoring systems placed around the UK together with measuring vehicles if necessary, to track interference sources.
One time the interference being assessed was found to be caused by Jammy Dodgers biscuits being cooked in an oven!!
James described how the station has been testing the use of drones for example to help diagnose problems with radio masts.
Passers-by have recently asked them to broadcast a request as they thought it was 3 Counties Radio.
The station has an amateur radio call sign of G8GPO and is active on 475kHz and other bands.
