[WL-USERS] CW/PTT/FSK Interface

[Rosenberg.Eric@orbcomm.com]

Has anyone built a 3-in-one interface (PTT, CW, FSK) for WL or the other
contest programs using a single serial port?

I've been having problems with my parallel port optoisolated CW/PTT
interface (RF feedback, I think) and am thinking about dumping the entire
kludge and starting again.

Are optos 'required', safer or otherwise have an advantage over a simple
transistor circuit for the serial port?

Any advice is greatly appreciated!  [btw, rig is Ten Tec Omni-6+]

Thanks in advance,
