High power tuning caps?

Fixed components and relay switching with computer control have taken

To a large degree but a motorised roller coaster and variable
capacitor(S) can still prove a useful set up. I used to run just such a
setup, with the L&C positioned near the feed point. A couple of motors
with a simple gear chain etc. and some limit switching can be build in a
few hours. I had previously drawn out a simple method for others and had
seen it working. Even without any feedback to the operating desk it was
surprisingly easy to use.

I've used a tapped coil and switch caps as well (also remotely) but the
motorised system gave better control and, once tuned, didn't require power.

I now use an Auto ATU (an SGC) which is marginally quicker to use.
