=F0  In my experiences, at 3000Vdc, a Mu=3D130 3-500Z will produce a =
linear=20
output of about 800w pep -- provided it has c. 70w of drive.  With a Mu=20=

of 200 (Amperex 3-500), a bit less drive is required but the pep out is=20=

the same.

=F0  There is nothing about telling the truth in Part 97. As a well =
known=20
amateur in North Hollywood (WA6MFJ) says "you don't have to tell the=20
truth on amateur radio".
