    Nothing new but my version of a se567 cw zero beat led indicator.

    Hello all

    I have been working on a few projects and one of them is ready

    CW Zero Beat

    I don't know if anyone would be interested in a CW Zero Beat but I have 9 in kit and 1 built for testing in the video. If more people are interested I will make more, seeing as this is a CW only item I did not want to be sitting on 100 of them with no interest.

    They are 13$ shipped US or 13$+actual shipping outside conus.

    I can build them for you for 2$ extra or only solder the surface mount and allow you to build your own.

    J1-Power in 9-12V

    RV1- Audio in adjustment

    J2- Audio in

    RV2- Center Freq Adjustment

    Please contact me direct via qrz listed e-mail or private msg.

    Thanks for all the response, it was kind of a surprise honestly.

    All kits are sold or spoken for at this time. I have more on the way so if you missed out and still want one let me know.

    is this just a simple audio in / ground connection to the board ? Are you pulling audio in parallel to the speaker? What power requirements are there ?
    I'd like to integrate one into the chassis of a small extension speaker for use with a ubitX as I've always been tone-deaf.
