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."

Beautiful stuff there. I've worked a few of these and always cherish the contacts. True works of art.

Yes, confirm. I've never made TNT before, but plan to try one day - got pair of RK-25 tubes for this project.

I'd like to learn about what the meters are measuring here and how accurate they are or are not? Does the ham who created the project or another who is familiar with the question care to engage? K9SPY kc.koellein at gmail dot com Thx! -kc

The first ammeter is for the plate DC current, second one is a thermocouple type, designed to measure an antenna RF current.
