Losses in auto ATUs?
In the Feb 2016 edition of BadCon (The journal of the RSCB) there is
a picture of an internal auto ATU in one rig, and the switchable capacitors do not look like they are particularly low-loss. Even manual ATUs tend to be dummy loads under some condx, so is there any concern or interest in that auto ATUs might be unduly warming up the shack? |

I don't think loss is a visual property. Even manual ATUs tend to be dummy loads under some condx, so is there any concern or interest in that auto ATUs might be unduly warming up the shack? One can only hope the manufacturer used reasonably good components. -- Jim Pennino |
