I made a hf atu. Tends to arc across tho above 100w. Pity Bean hasnt got his
finger in it at the time.

Picking up a project that has been put down for 6 months - has
anybody got experience of manufacturing their own ATU
switches out of brass, either as knife switches or else as
ginormous banana plugs which then engage axially with
a sliding action?

I have conceived of a design for an experimental ATU that
allows changes of configuration (including the safety earthing
when not in use) using only 8 single-pole single throw switches,
into the most common configurations.

(I may have mentioned this before in this NG, sorry if so and
thus inducing ennui in my loyal-but-paranoid fan-club of CB types
who seem to hang on my every word)

I made a Z-match, it tended to arc on 40m, but not on other bands. It
depends much on the antenna impedance
