On Page 39 of the Nov-Dec 2024 SARC newsletter "The Communicator"
Wow! Beautiful workmanship! The builder is too modest!
ReplyDeleteHe did do a great job. It looks more like a rugged industrial piece of equipment than a homebrew project.
ReplyDeleteHe is a craftsman and to be admired
ReplyDeleteTerry G4POP
I wanna know what kind of solder he used :-). And check out that homebrewed key! Sweet. 73 from Oxnard, CA
