Looks really good 💯👌

These work very well, and of course if you have spare RG400 left over it makes great patch leads. 73

Great Info. I've been looking for a video like this!

Hi Darren,
Great build. G3TXQ has very good common mode choke info on his website. RG400 uses a Teflon dielectric center insulator, so any soldering iron or gun wouldn't come close to affecting it. I've used a plumbing torch to install PL-259's on RG400. 73 WJ3U

An easy way to do the braid cleanly is to use an awl at the end of the insulation and work a hole in the braid until it's big enough for the center conductor to go through. Then do a hard bend and you can fish the center out through the hole and use the awl to work it out. After the center is out you can work the braid and it looks like it was made that way. And the end of the braid will be pristine for soldering to your ground lug.

Good job capt. Did you hear from yaesu about your rotor?

[@DarrenN4VFR]

Yeah, rois fine so either the controller or wiring may be bad.
