Digital Master 780 DM780 CW Send CW Interface – How To

K0PIR

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.

I use a 7300 as well as a 7610 and I enjoy reading all the information about the sets very useful.
The one comment I have between the two set is concerning the preamp. 7300 Preamp 1 and 2 work on all bands but with the 7610 only preamp 1 works on all bands and 2 works only on the 10m and 6m bands.

I think you are using the W1GEE DB9 to 1/4″ CW cable. I ordered that cable from the N3FJP CW web page. You also had a link to a USB to 1/4″ CW cable. Does that also work to key the CW on a 7610?

Just tried setting up my IC7300 with DM780 to use transmit CW. I plug in the USB to 1/4 in. Interface cable, rather than a com port it shows up as “USB PnP Sound Device” in device manager. And DM780 dosen’t key the radio to transmit. Any suggestions? Thank you. John Zempel KG4OLG

Trying CW with HRD/WKUSB but must be overlooking something. WKUSB works fine standalone (keys my rig ok), and it connects to HRD. When I type CW, 7610 xmit light goes on but no CW. (I can hear the WKUSB sidetone ok). Have USB cable from PC to WKUSB and cable from WKUSB CW out to 7610 manual key input. Any ideas? – Tnx

Rich, vy helpful. Based on that info, I moved key line from Port 1 to 2 on the WKUSB and it solved the problem. New issue: When I click the Send button, I can type in text and it gets sent, but when I click the Stop button the Send button remains active (greyed out). To clear the problem, I have to click the Test button in the Winkeyer button. I’ve attached a screen shot. Any ideas? – Tnx es 73.
