- Hellschreiber is an interesting ham radio mode developed back in the 20s. It is a bit strange and different, but fun. I'll explain what it is, then I make a couple contacts during the Hellschreiber contest.
- SigJenny turns your PC into a flexible and powerful audio signal generator for free.
It can create multiple waveforms, sweep, fire single or repeating tone bursts. You can save your sound as a wav file, display a frequency response, use SigJenny a bit like an oscilloscope, and do a very good impression of a police car!
