[Dx4win] SO2R Question

[Randy Farmer]

I used a DX Doubler with DX4WIN for several years and it worked fine. 
You MUST have a real LPT port to drive it; a USB to LPT converter won't 
do the job. In version 8.x, the logic state for control for the radio 
switching LPT pin can be controlled. Make sure you're in "Expert" mode 
and open up the Preferences. On the CW tab just tick the Radio 1/2 
signal "Reverse" box at the top of the window. I'm not sure if the LPT 
port band BCD code follows the radio selection. Good luck.
