Re: [Fwd: coating]

Gary,
        It sounds as if your secondary is very over-coupled and you
will have to raise it a bit. I found it amazing that raising the
secondary just 1/4 inch made a world of difference and stopped the
annoying secondary strikes. I did later go back and purposely
over-couple my secondary to get some pics of the strikes and the
glow of the field.
