[R-390] Kahn SSB Converter

[Barry Williams]

Dan,

I know of your extensive aviation experience, so I would almost always 
defer to anything you said regarding this. You have way more hours 
logged that I ever did, and in some pretty fantastic planes too. The 
only references I saw in print about Speedbirds were to the Concordes, 
but I certainly tend to believe you over them.

That particular exchange was between a Concorde because they reported 
having to drop back to subsonic flight. I have the whole log somewhere 
since I save all of that. From memory, I think they were experiencing 
runaway N2 temps. By the way, I logged that one day with a HP 3586B and 
a few feet of wire for a test antenna while it was on the work bench.
