Mike, I have the same combo and tried a Win 7 machine (laptop) with a USB-to-Parallel adapter to no avail (I'm neither a PC guru nor patient). I gave up and just keep a legacy machine running XP for this controller. It has worked reliably since I bought it more than a decade ago. 73, Jerry, M0GOE
*********************************************************************************************** Greetings,
I'm still running a Uni-Trac Parallel port interface with ZL2AMD's Uni-Trac 3.0.b software on Windows XP to control a Yaesu G5400B. Yes its old, and yes, it works fine. It even has DDE capability to run it from SATPC32, which is credited to DK1TB (Erich - SATPC32 Author).
Question, is there anyone out there using this tracker on an O/S later/other than Windows XP ?
(If so, I'd be interested in the details)
