WinKeyer USB ACC Cables for RTTY FSK Icom 7300 and 7610

Below is how I made WinKeyer USB ACC cables (7300 & 7610) to transmit RTTY FSK with the WinKeyer USB. I finally got the opportunity to use my WK3 with N1MM in last weeks CQ WW RTTY contest.  This only works with WinKeyer 3 and the latest firmware. See my article here on upgrading the WK3. This does not work with HRD and DM780.

I am a fan of the WinKeyer USB. It’s the best way I’ve found to use a paddle with my Drake TR-7. It’s the best way I’ve found to send real CW and RTTY FSK from Fldigi.

WinKeyer USB ACC Cable for the Icom 7610

This one is tricky to make. I bought 5 connectors off E-bay and destroyed two before I got it right, hi hi.

WinKeyer USB ACC Cables

Using a patch cable such as this, RCA Audio Cable 2 RCA Male to 2 RCA Male, cut off one end and solder the center wire of the red plug (RCA audio cable) to SEND and the white plugs (RCA audio cable) center wire to RTTY. The shields from the RCA audio cable go to GND.

WinKeyer USB ACC Cables

This one is very easy to make. Using a patch cable such as this, RCA Audio Cable 2 RCA Male to 2 RCA Male, and using the supplied connector from Icom that came with your Icom 7300 solder the center wire of the red plug (RCA audio cable) to the SEND wire (DIN plugs orange wire) and the white plugs (RCA audio cable) center wire to the FSKK wire (DIN plugs black wire). The shields go to GND (DIN plugs red wire).

Confusing? It’ll make sense when you have your hands on the parts.

Connecting to the WinKeyer USB

You’ll have a standard USB-A to USB-B cable going from the WK3 to the computer. For the ACC cable you made, plug the red connector into the PTT of the WinKeyer USB and the white connector into the KEY.

There is an excellent document here with pictures from the K1EL website. In addition I show the setup in the video below.

I also have an article on Ham Radio Deluxe and DM780 using the WinKeyer USB with CW.

I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. On my YouTube channel I upload videos on the Icom 7300 and Icom 7610 along with Ham radio software programs. I hope to inspire people to try new things in Amateur Radio.
