    Is it possible to connect the HDSDR software to a Yaesu FT-450D using only the USB (USB-63) to RS-232 cable?

    I saw a YouTube video from a station that accidentally connected a 450D to his HDSDR software via a 'RealTec' dongle. Please see the YouTube video below. I don't current own the RealTec device. However, I do have my 450D hooked to my computer via a USB-63 cable (USB to RS-232) and I am using the PCC-450 software to control my 450D. However, it does not have the "waterfall" display like the HDSDR app.

    Any information provided will be appreciated!

    im getting parts together to try with a regular lna,not hi z. testing an idea? report later , cables on sat i hope. found tie points on 450 board,very tiny parts to be CAREFUL WITH...!!
    using short cable inside to a new hole on rear panel for sma conn. that will feed a cable to the sdr dongle or rsp duo.
    wonder if i could use the duo hi z input with a "balun" to the lna inside? just though of that?
    i dont know these parts, yet..

    it will look good even if it dont work,!!

    btw,the link info on this mod is misleading on tie points for rec power and input signal. take a good look and verify if you try it.
    the pics are misleading.
