Re: [wsjtgroup] Re: schematic
- John - take a look at http://www.soundcardpacket.info/ - plenty of info
to "roll your own" - look under the interface heading/tab. I prefer the
optoisolator/coupler (4N33 family) to control PTT.
Also see Ernie Mills, WM2U, pages on basic interfacing at
http://www.qsl.net/wm2u/interface.html - plenty of ideas there also.
