[R-390] NOS R-390A's

[Bob kb8tq]

Hi

The sort of testing you describe was “old” when I was in school. That was 
errr …. a very long time ago. We went over a lot of the data and procedures
as part of class exercises in circuit design. It’s also been part of a number of
system designs I’ve been involved with over the last 40 years.
