Today Thursday 18th May 2023 Steve M5ZZZ and David G1WVO met up with Steve G7JHU from Chapel St Leonards and Ant M0HAZ from Woodhall Spa in the NAAFI at East Kirkby prior to opening the Radio Room (GB2CWP).
The museum was very busy with visitors with Lancaster and Mosquito taxi runs programmed for the day. Steve M5ZZZ and Ant M0HAZ had a steady flow of interesting visitors in the radio room.
David G1WVO and Steve G7JHU set about repairing the T1154 after a badly burnt carbon resistor was found in the PT15 grid bias circuit on their last visit. It’s possible with the poor antenna connection this may have caused one of the PT 15 output valves to flash over internally between the screen and the grid thereby burning the resistor out.
David G1WVO removed the damaged resistor and soldered in new one. A good look around the transmitter by Steve G7JHU found no other damaged components. The repair work now lets the Transmitter operate in its original wartime state.
Several basic tests were carried out on the transmitter after the power was switched back on. The transmitter loaded up on 40 and 80 meters with an estimated output of 60 to 70 watts.
The intention is to use the transmitter on the air from time to time and load it into a dummy load for demonstrating to visitors.
We need to replace a 4 pin Jones input socket which is internally damaged this feeds the headphones and the morse key. I wonder if any club member has a 4 pin Jones socket, they could spare please?
The radio room at East Kirkby is open to club members on the third Thursday in the month, please check the LSWC website for dates.
