[bars] VarAC with IC-7300

[Juan Jiménez]

And that is the real value of ChatGPT, the ability to greatly reduce the
time needed to research the answer to a question. I use it every day at the
office to find the answers to complex technical questions. Sometimes it
gets it wrong, but strangely enough, when I point out the mistake, it
offers the correct answer. Weird.
