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!

Building A Vintage 1929 Style Transmitter - Best HOWTO

Yes, Best HOWTO Ever, but not mine - hats off to Steve VE7SL. I've found this great article reading the Glowbugs mail list and I have to post it here because this article is a pure gem. Even if you never did it before, after the reading of that article you can to, you have to make your first TNT or Hartley transmitter and trust me - it is only first steps into the amazing world of glowing history!


BUILDING A 1929 VINTAGE TNT TRANSMITTER
Quote:

"After some research into the 1929 transmitter style, it became apparent that most amateurs of the period were using either a Tuned-Plate-Tuned-Grid (TPTG), a Hartley oscillator or a Tuned-Not-Tuned (TNT) design. I can well imagine the countless late night 160m AM QSO's of the day discussing and arguing the virtues of each amateur's chosen design. Eventually I decided on the TNT, a simpler off-shoot of the TPTG design."

Junkyard Warz Novelty Transmitter by W9QZ

Several month ago I found a great, probably most artistic Glowbugs Radio homebrewer in the WEB - Rick Weber, W9QZ. I've been very impressed, downloaded some beautiful photos of those stylish Rick's HAM-Radio artefacts and, naturally, forget to check this page again - it was my mistake. Take this:

Rick:

"Junkyard Warz Novelty Project. This is a working Hartley transmitter I built with all non-radio components except for one 027 vacuum tube."

Big Nick and the Cydecos - Glowbugs Radio Hide-And-Seek

Today I decided to become (at very last) a real blogger and to invite some celebrities as a trendy stuff. But as it turned out, neither Madonna nor Britney Spears did not make the tube radios, Arnold Schwarzenegger is possible and would do, but too busy at work, and Michael Jackson .. Okay, let's not about sad - the result of my quest was a brilliant success:

Evergreen Exciter for the Special Night

Several days ago I listened to the completely empty ten meters band. There was a lot of noises, quiet CB chewing and nothing else.
Suddenly I heard a slow, quiet, but very clear telegraph code, resembling W1AW QST. I have not heard the beginning, but wrote all heard:
