One of the biggest problems is that you get links to old sites with outdated information. See below.If you search Google for Amateur (or Ham) Radio Software, you will get a lot of results, but not a lot of information. On the CW tab I am using the Com port for my CW interface and then a few other minor tweakes so the CW sound good. See the video on setting that up in the Icom 7300. Control CW pitch in the radio, but control CW speed in DM780. This way I can have a key and the PC hooked up at the same time. It’s a 1/4″ jack, but thank goodness we can use a splitter, You don’t have to, but I like it in line. With the Icom 7300 we only have one CW jack on the back of the radio. UPDATE : Dug out the old CW USB KEYING CABLE and have been using it with the Icom 7300 in my camper.

Check the RTS CW keying in DM780.ĬW USB KEYING CABLE (I have not seen any being sold from the USA). UPDATE : Received my new CW (USB) interface and it is working FB. It is less expensive, but may not work as well. I have a different one (USB to 1/4″ plug) on order. I think it is a W1GEE cable, it is essentially this one: Using CW selected in DM780 and a CW interface cable is good solution. CW (KY CMD) works okay, but I always seem to run into problems eventually with it. CW (SSB) is not recommended, at least in the US it isn’t. There are at least a few ways we can send CW with DM780 and I have tried them all over the years with the exception of a Winkeyer or devices like that. See my previous article on DM780 CW Decode. Digital Master 780 sends good CW using this type of interface, but if you want to go all out try a Winkeyer. It was used with an old Kenwood and I use it with the Icom transceivers I have now. I have been using the same CW interface for many years. How does a good CW interface cable work with DM780? Great and it just plugs into the CW jack on the back of the radio. I have a video out on this, but I have more information and pictures in the article.
