TNT (Tuned Plate-Not -Tuned Grid) 1930's Transmitter Put on the Air

We have vast radio resources at the New England Wireless & Steam Museum. One thing we have a good stock of is homebrew amateur radio transmitters from the 1920's and 1930's. The TNT transmitter was first popularized by an article in the December, 1929 issue of QST (p. 25). Our radio was built around the time the article written by George Grammer was published. We intend to enter this radio in the 2023 AWA Bruce Kelley Memorial QSO Party (Nov. 11-12 and 18-20).
