AVT (Original Version)

This was the original AVT I designed before AEA commissioned me to do a more capable version (here ) for them.

This model did AFSK F/D in such a way as to be optimized for SSTV by measuring the time between zero crossings. It connected to the Amiga's parallel port. It required an external 8 VDC to 12 VDC power source.

Everything was done directly in hardware in this design, there was no CPU on board. I designed the PCB in Boardmaster.

The elimination of the IC part numbers was pure paranoia on my part. I laugh at myself today about it.
