Here is Dave's beacon keyer, built in a mint tin. It has proved to be a useful addition to Dave's shack, enabling him to conduct beacon tests on the air. It operates from a 9v battery, with little power drain.
I am very grateful to Dave, G0DJA for allowing me to add his files to my web site. He can be contacted by email: dave.ackrill@powergen1.powergen.co.uk
