A Powerful CW Tool – CW Skimmer (CWS) 170 kHz Wide



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.

    Hi Rich

    I’m still using version 1.03 on my IC-7610, if I upgrade to version 1.2 will I lose all my memory settings in the 7610???

    Same question for CW skimmer and HDSDR????

    Thank you in advance for your answers

    Hi Rich,

    What are you using the CIV port for?

    Hi Bill,

    Nice to hear from you and great question. I believe so, because one or two of the updates required loading the settings back for me.

    If you save your settings prior to updating the firmware, you can load them back after the update.

    CWS and HDSDR I don’t know, but I would not think so. I updated my HDSDR and Omnirig without issue.

    Hi Brad,

    Nice to hear from you. I have a CI-V cable and it is connected to the CI-V port on the rear of the IC-7610.

    I am using it in CW Skimmer for OmniRig instead of the Kenwood and CAT to HDSDR. Nothing wrong with using the Kenwood and CAT to HDSDR, but I don’t care for the flashing frequency in CW Skimmer when using it.

    It comes up as my COM12 in my PC. I have a few of these cables I use on and off for various things.

    FTDI 3 ft.FTDI 10 ft.

    Hi Rich,

    A problem I’m having with the CWS Wide is that the spots from CWS to N1MM are off the actual frequency. For example: CWS reads the W1AW code practice transmission at 7047.5, but the CWS spot to N1MM is 7016.1. Clicking on W1AW in the band map tunes the radio to 7016.1 not 7047.5.

      Hi Kermit,

      Nice to hear from you. I have not run across that.

      It must be in the settings somewhere.

      What does it look like in HDSDR? If it’s off I would start there and check the settings.

        Solved the problem of the off frequency spots in wide mode by doing removing N1MM and CWS, doing a fresh install of both, and setting up only for CWS wide operation. I haven’t reloaded for narrow mode yet, but obviously I had some setting wrong when moving from narrow to wide. This may be helpful if anyone else encounters an issue.

          Hi Kermit,

          Thanks for reporting back and yes your experience will help others.

          It takes a little getting used too and I took it slow for a while by just running narrow before delving into wide.

          Happy holidays and best 73,

    I’m trying to use CWS with Fldigi and ACL and my 7300. I have both a USB Cable and CI-V cable. Do I need to use OMNIRig? Do I need to use the stereo cable from the 7300 phone jack to my computer sound card speaker jack also? I think I’ve read everything you’ve written about CWS and Pete Smith’s intro to CWS.
    Thanks, Tom

      Hi Tom,

      Nice to hear from you and that sounds like a great setup you have going.

      Yes, I used Omnirig when I had HDSDR going with my 7300, so I would try it with CWS.

      You should not need a stereo cable. All audio is through the USB cable, the USB Audio CODEC.

      FWIW I never did try CWS with the 7300 and HDSDR, but I heard other Hams used it.

      Good luck, let me know what happens.

      Happy holidays and best 73,
