Re: Once again: Realistic BBQ Dish Gain with OriginalDipole Feed, an



Actually, I think Pablo has already done that development. Surf to
http://www.ea4tx.com/ and have a look at his controllers and software.
Interfaces with any and all software that uses DDE. I use it here on my TVRO
and the program/interface works great. My problem is coming up with
something simple for the az that will survive a New England winter...
