#780 ATU-100 Antenna Tuner Build and Measure (and a story) HD

Episode 780 ATU-100 Antenna Tuner build and measurement. I try to look at the tuning on a VNA. I need to trick the SWR bridge. Also a bonus story time. I did eventually build it all and try it out. It works as well as the internal tuner of the ICOM 7300. One of the downsides, it does not remember bands, so each time it has to auto tune.
