I dropped an item behind my desk which up against a wall. I found a scrap of paper there that had been there for almost 18 years. Enjoy! What, don't you remember 75 baud FSK modems? Kids these days! John |

I didn't even know where the computer was. Al |

A very popular HF ham radio "keyboard to keyboard" digital mode today is PSK31... all of 31 baud! (But also all of ~31Hz bandwidth...) Some "speed demons" re-packaged it into PSK63... |

They have purchased two of our VME arbitrary waveform generators, close to $5K each, to generate Morse code. John |
