TNT Uncovered - Flea-Power (QRP) Telegraph Transmitter in the Pilot Radio's "Radio Design" magazine, 1930's

I found this article in the Lloyds Dipsy Dumpster - site, where you can find a lot of rare vintage radio articles, manuals and data sheets.

It is remarkable, that "Pilot Radio & Tube Corporation", well known as a manufacturer of the great Super-Wasp receivers, was a publisher of a Ham-Radio literature, handbooks and magazines, as well as many of early radio manufacturing companies. As for me, I like that sort of advertising much more, than modern spam in my mailbox and if it would be possible, it should be a nice choice to make this QRP transmitter using a native Pilot's parts only.

Anyway, when I've read this article, one interesting fact has drawn my attention - I can recognize the TNT when I see a TNT design, but in the text this transmitter has been described as a TPTG.. Moreover, there is a grid capacitor on the assembles view, but with a opposite description below: "condenser is not needed". So, in the article we can see that mysterious moment, when as the chrysalis becomes the butterfly, TPTG transmitter was transformed into a trendy TNT.

Real Radio?

Yeah, it glow!

Breadboarding the new T.N.T. based transmitter design. Coming soon.

Radio Girl

Occasionally found this Radio Girl album browsing the web, I knew that it is slightly offtopic here in this blog, but I have to post it anyway. It is soft acoustic rock music by Nick Wilkinson, naive young guitar dancing around the vintage radio set, maybe too sappy, but it is exactly as I like. And look at cover art - how could I resist, who can resist at all? Listen to the Radio Girl!
