Thanks for the comments guys. I had a chance to play with this a bit more and am now able to both xmit and receive cw using both Fldigi and HRD5.0.
Problem was I had the K3 set for AFSK rather than DATA A. Changing to DATA A allowed me to transmit via the PC sound card and VOX. Interesting observation was as I tried the various data modes for the best sounding received cw signal (comparable to actual cw mode) I thought PSK D was stronger and more defined to listen to. Listening to cw via DATA A was weaker and less defined but still seemed to provide decent decode by the software. Thanks again. chuck af4xk -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-cw-pc-program-problems-tp5179084p5184409.html Sent from the [K3] mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
