Hi group

If Steve will give permission, I can  order a batch for the new pcb and 
send them from here WW.

The main PCB will send with 10 RX-amps PCB's
You may select the original by W1FV , the VE6WZ version, or our version 
with smd components (SMD soldering with a electric cooking plate. -

> 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.
