LF: 300W-TX-G0MRF

["dj9dw" <dj9dw@t-online.de>]

Hello group,
as I can't get in contact with David, G0MRF, I want to spread out my problem
here.
The TX works fine except the outputtransformer T2. There is heavy ringing at
abt 1 MHz. Now I figured, the inductance seems to be abt 300uH from drain to
drain. That shure is far too much.
Could it be that David has changed the toroid - type to one with higher u so
that 10 turns primary has to be reduced?
Your help is very welcom, I am stuck.

Regards, dj9dw, Peter.
