Building a 1929 Vacuum Tube Transmitter

摘要

The logical choice seemed to be 1 60 meters, as it comes closest to the famed "Keep them below 200 meters" edict of the era.2 With the receiver completed, it was time to address the transmitter. Self-rectification was a practical simplification, as good high power rectifiers were a real problem, as were power supply condensers [now called capacitors - Ed.] larger than a few microfarads. [...] perhaps the most pleasure comes from making parts the same way they were made originally.
