24 kHz CW Skimmer with the Icom 7610 | 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.

    Hi K0PIR,
    RE: Frequency is flashing in CWS.

    For me I found that instead of using Kenwood, the flashing stopped if I configured the Cat Interface to use “ZS-1”.

      Hi Richard, nice to hear from you and thank you for posting the information. That’s great! It bugged me a little bit.

      This will help others as well, so thank you again.

      Best 73!

    Hi Tom,

    Nice to hear from you and thanks for the comment.

    I have not. I got HDSDR going with the Inrad RX7300 and SDR dongle, but never did attempt CWS.

    I hear people have done it.

    You might want to check the Icom 7300 forum in Groups.io. I know they were discussing it a while back.

    Have you explained how to setup CWS with the IC-7300?

    Hi Rich,

    I have set all this up and it’s working fine. However my HDSRD has no I/O gain selection available, so can’t make minor tweak to CW skimmer. Have you faced this? Is there some other setting which prevents adjusting the gain?

      Hi Jarkko,

      Nice to hear from you and thank you for commenting.

      Yes, it happens to me. Open HDSDR, start it, click on Options>Output Channel Mode RX and select “IF as I (Left) / Q (Right)” again. After selecting it again the slider should show up.

      See if that works.

    Hello Rich
    I finally have HDSDR and CW Skimmer working with my IC-7610. My WIndows 10 Lenovo computer and HDSDR did not see the new com0com ports. Finally I removed com0com and loaded Null Modem Emulator by Eitima and no problems assigning two new ports for HDSDR. Also CW Skimmer did not have 7610 in CAT setting so I stayed with “Kenwood: and the “flicker” freq readout
    Again MANY Thanks

      Hi Ivars,

      Nice to hear from you and thank you for commenting.

      I just started using Eitima on my new laptop and I am glad you like it. I have no used it much, but it’s a nice program.

      You may have an older version of OmniRig and that’s why the IC-7610 doesn’t show up. If you install the latest it should work FB.

      Thank you again and CUL.
