Frank Statham provides the instructions on how to flash up the 277Q radar along with some additional notes of explanation."I always enjoyed rotating the variac to bring the generator voltage up to 10kV. I could hear the singing of the primary AC voltage increase and then what I would call the 'tenseness in the air' as the voltage took hold.
The angle information at the bottom of the instruction sheet refers to the antenna position required to find the weather balloon at launch. Of course the antenna azimuth would be astern, as the ship would turn into the wind so that balloon would blow free and clear of the vessel. The higher the wind speed at launch, the lower antenna angle required.
Often the operator would accidentally acquire the balloon on an antenna side lobe, but that would be noticed within a few minutes as the balloon ascended and the pip faded out much too soon".
