Thanks for your e-mail.? I have to confess that hardware is not my strength so I? used a parallel interface provided by W1GEE.? I'm sure that there are some schematics out on the web somewhere.? I wish I had the time to investigate further.? My other schematics came from a good ham friend of mine.
I'm sorry I can't be of more assistance right now, Dee.? I hope you continue to enjoy using the software.
