Class E for CW and digital modes

Postby RonSkelton » Sun May 10, 2009 3:36 pm

Greetings all
I am just beginning to get acquainted with Class E projects with a literature search.
What I am missing are projects in the 300-500 Watt class for 10MHz and above.
I would appreciate some direction
Thanks Ron W6WO W6WO@K6BJ.org

Welcome Ron...

Projects above 40 meters haven't been discussed much. At least, not in great detail.

There was one thread that I tried to get discussion going about 10meter AM , class-e.

Sure you can do CW easily with class-e...
And I know Floyd, WA2WVL has built a 40 meter RTTY amp...

Would be good to get more of the highger frequency experiments going, that's for sure...

Diego - the article does not show the source. Please, tell me how you found this article. Some of the concepts are very useful.

Ron,

Microsemi has a number of pertinent papers on their web site. Unfortunately, it's very difficult to find anything there. If you go to www.microsemi.com and enter "class e" in the search bar, you'll be directed to a number of insightful documents.
