The K3 is "data ready". What that means is that you can simply connect two stereo cables with 3.5mm plugs between the K3 and your computer soundcard. Add to that an RS-232 cable to handle the PTT function and you can operate all of the data modes. The K3 has a DATA mode in addition to SSB that turns compression off for best IMD. There are 4 sub-modes for DATA mode - 1) DATA A for most soundcard data modes - 2) AFSK A for soundcard generated RTTY (RTTY works in DATA A too, but AFSK A adds some features. -3) PSK D (for PSK Direct) which allows you to enter text from the paddles and it will be converted to PSK31 signals in the K3 with decode of the received signal in the VFO B display. That is handy when you want to operate PSK without a computer. Finally -4) FSK D which can be used just like PSK D with input from the paddles and text display on the VFO B LCD area, but can also be used with true FSK with the input on the ACC connector.
The bottom line, you can easily use the K3 on data modes, and the interface is built-in, no need for an external data mode interface box. There are transformer isolated LINE IN and LINE OUT connectors on the back of the K3 just or this purpose (and more too). 73, Don W3FPR Emilse Peraza wrote: > Well tahnks to everybody that has answer me, so seems like a lot of you guys > use the K3 in CW what about SSB, I ma mostly interested in SSB PSK31 and some > MARS, so any ideas about that aspecte compare to the jap radios > > > EMILSE > > KE7EOZ > > ______________________________________________________________ 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
