Ian, thanks for the excellent summary. That could be a classic RadCom or
QST article on its own!
I think it's worth mentioning that operation of PC-based VNA devices is not
as intimidating as it may first seem. The simple OSL auto-cal routine does
much of the heavy thinking and set-up. In speaking with other ops, many
seem to stick within their comfort zone of a broadband detecting device, the
"Type 1" SWR analyzer you cite. If curiosity ends with SWR, then I suppose
there's no need to consider a VNA. But, after running a few VNA sweeps, an
entirely new world opens up with even minimal knowledge and skill.
