>   Message-ID:
>   Content-Type: text/plain; charset=utf-8
>
>   Hello fellow DXers,
>
>   Today I uploaded a YouTube video describing my new 9 circle combiner
> board PCB design that has small Murata SMD CMCs on each RG-6 feedline.
>
>   I include PCB file links to download in both KiCad format or a zipped
> Gerber folder if you want to build your own. A BOM and an image of the
> schematic is included as well.
>   This is the 9-circle array that was designed by John W1FV.
>
>   I review why we need these CMCs, I talk about these small Murata
> chokes and some VNA tests I did and how these same units can be used
> as Magic-T?s.
>   The new design also has a pin-out for the vcc and relay control
> lines, has the option for gas discharge tubes on the vcc and control
> lines, and the board has a slightly larger footprint than my previous
> designs so its its easier to access the F-connecters for field
> installation.
>
>   The evaluation is still on-going at VE6WZ, but the board tested very
> well in the shop with the VNA, and I used it this weekend for the CQWW
> 160m test and it performed well.
>
>   I know there are many that ?don?t like? to watch a video, and I may
> build a PDF document, but in my ?prior life?, all I did was make
> technical/ scientific documents and I?d rather not do that anymore.
>   It?s much easier to say things quickly in a video. If a picture is
> worth a 1,000 words, then a video is worth a million.
