Larry, et al,
I know the point you are trying to get across. That is you do not feel
comfortable with the HV on while in the receive mode. I think it is easy to
understand. It may not be practical, but I laud your efforts for installing
the necessary devices needed to make this happen. There is definitely some
fore thought in your designs. I had a friend of mine (now SK), that was in
"receive mode" when all of a sudden, he saw his Ip meter from his 4-1000
amp, go flying by him. There was also some extensive damage in the bleeder
resistor network. So there is something to say about accomplishing this
feat.
What I would like to know, is if you have some sort of delay worked out
so that you don't generate RF until your Ep is up to full potential and is
stabilized.
Some of us see the merit in your actions.
73,
Mike(y)
