In a previous post, I outlined how some radio amateurs in the UK are
obtaining special permits to operate and experiment on the 40 MHz band. As
part of the feedback, someone mentioned the old G9 callsigns which were a
Test & Development license in the UK.
Anyone familiar with old copies of the Practical Wireless magazine will remember antenna articles and designs by Fred Judd, G2BCX. He popularised antennas like the Slim Jim for 144 MHz and he used the callsign G9BTN for
much of his work.
Lewis, M3HHY put together a nice video about the history of these G9
callsigns and it's embedded below.
