Weekend Project - Two-Tube Spy Transmitter

From the look around his shack Helge Fykse (LA6NCA) really has a thing for old technology. The typewriter, the rotary phones, the boat-anchor receiver — they all contribute to the retro feel of the space, as well as the circuit he’s working on... The tiny transmitter is built into a small metal box, which is stuffed with the resistors, capacitors, and homebrew inductors needed to complete the circuit... Almost every component used has a vintage look... But does it work? Of course it does! more
