This compact 80 meter transmitter designed especially for the novice appeared 70 years ago this month in the July 1952 issue of Radio-Electronics.

The two-tube circuit used a 6AQ5 as a Pierce crystal oscillator, with a 1625 serving as class-C final amplifier. The 1625 is the 12 volt version of the venerable 807 tube, and according to the article, it was possible to buy several of the on the surplus market for the price of one 807. Since a separate 12 volt power supply would be required for that tube, the article suggested using two 6 volt filament transformers in series.

According to the author, good results were had with a 20 foot antenna at 12 feet.
