Hi Ed, I don't think they say it must be done, I think they say it's
usually better to do it that way. With PC board throw bars to insulate the
points there's really no more work involved isolating frogs than there is in
not isolating them so anyone building a new layout should consider it. If
anyone already has a complete layout with solid metal throw bar electrically
connected points they are probably not interested in the discussion anyway as
they are already aware of the options?....DaveBranum
