[Elecraft] Signalink and K3 (you do not need need a Signal Link)

[RIchard Williams via Elecraft]

Jorge,
Interesting enough, at a recent club meeting, the presentation was on using the SignalLink as an interface between your radio and computer to operate Winmore using RMS Express.   Until reading all the threads the last couple of days, I was contemplating purchasing a SignalLink;  however, last night I tried hooking my K3 directly to my computer.
All I did was connect the line out on the K3 to the mic in on the computer (using a stereo cable) and the line in on the K3 to the headphone jack on the computer.   Only thing missing was a way to key the K3.   This is easily solved by using the RS-232 port on the K3;  hook the K3 RS-232 port to your computer (since my computer does not have a RS-232 port, I used a RS-232 to USB dongle).  First go to the config menu in the K3 and find "PTT -- Key";  set either DTS or RTS above "PTT" to on.   Now open RMS express; in the setup there is a "PTT Port (optional) setup.  Just selected the correct serial port (found in control panel/device manager), baud rate you selected in the K3 config menu, and use either RTS or DTS for keying (the same as you set in the K3 config "PTT --Key" setting).
Fired everything up, set the Line out gain (I found 3 to work fine), then go to menu and select "Line In" and set the mic gain to an appropriate level (4 worked for me); that was it, and I was able to establish Winmor connections on 80 and 40 meters.

Don't waste your money on it, Jorge. One of the Tascam units is far 
superior, and about the same cost. http://k9yc.com/USB_Interfaces.pdf
