VLF/LF Software Radio Transmitter

[Maitland Bottoms]

OK, 
 
Since there have been discussions on both LF and Software Defined 
Radios in the group, I pass along the following news... 
 
Read up on it here:

The gist is that you can download a floppy disk image and within a few 
minutes generate VLF/LF signals. 
  1. Read web page 
  2. Click on link to download floppy image data 
  3. Copy floppy image to a real physical floppy 
  4. Boot computer with said floppy 
  5. Attach parallel port antenna 
  6. Tune receiver to listen to transmissions 
 
Your mission, should you choose to accept it, would be to change the 
code a little to allow the operator to input a callsign and then pick 
OOK or FSK modulation options, and speed of morse code output. 
 
Extra credit, emergency power bonus points: 
Run this transmitter from a hand-cranked power source, using a manual 
powered computer described here:
