Hi Kelly,

I saw that article, too, and in my original inquiry I guess I focussed on
the RF aspects. No one replied though that they found chokes necessary for
ANY problems. Not to say that the arcing isn't a concern in some
installations. . .

I've decided to forgo the RF chokes for now (and I am planning to switch in
and out a matching capacitor to handle QSY from CW to SSB on 80M, so VSWR
shouldn't get too far out of hand). I'll post to the group if the chokes
become necessary.

Thanks for your input, and 73
