[TenTec] OT

[Steve Hunt]

Rob,

No, it doesn't annoy me; and I apologise if I have given offence by 
pressing the point too much.

It's just that I find a disappointing lack of understanding within the 
ham community about the properties of the various types of choke, and it 
isn't helped by some of the literature on the subject; Jim's paper is a 
notable exception. The result is, perhaps, that I force the issue more 
than is polite - forgive me!

73,
Steve G3TXQ
