Z-Match ATU built in 2014

Stockton Type SWR bridge

Planning





Building

First step is to take everything apart which took me about an hour or so to finish. Lots of de-soldering and unscrewing. The new build began as soon as the new enclosure came in the mail. It took about 7 days to get here from HongKong. First step is to arrange the inductor and the variable capacitors. once these components find it's place I then started putting the meter in place. Here's a picture of the final arrangement.

Big Swinging needle!





Meter showing roughly 3W of forwarded power on 80m.

Instead of just being a test build this ATU has now permanently sitting on top of my Yaesu FT-847. And the old T-match MFJ-941e has to find a new home.
