By the way I have hacked IRIG B using a proc called SXB and basic language. The specs are out there and its not all that hard. Two tricks that really simplify it. (Everything could be done in software) Use a stable external sine wave 1 KHz oscillator. I used a epson dip oscillator pretty stable. (Not in a time-nuts sense) Use an external amplitude modulator (Big words a switch) CD 4066 as an example. Thats what I did. By doing that the software is just changing the GPS code to the serial irig code. Regards Paul
