I bet not too many RSTs with a T of 9 were received back in the Spark Gap days! Great video -- thanks a million.73,WA5MUF (Same call sign since 1965)

I am sure glad I got to see a spark transmitter at last after reading about them for so long. I've never understood why they need a rotary gap. Looks like you could just key a stationary gap with high voltage applied to it and get a spark. If you feel like explaining I will be very grateful.

I think I heard someone running voice into one of those on 27.025 (The Bowl)

Thanks for posting that. One of my grandfathers, u6CCY, had one of those in the 1920's. I still have his original licenses that state he was authorized to run spark gap. Kewl! Rick N0VLF Colorado

Wow! So now I really understand why early ships' radio operators were all called "Sparks". Thank you very much. I've got to show this video to my XYL, but she already believes all Hams are crazy. :-)73 de David, vk2dmh
