I found some really great knife switches on the big auction site on the Bay.
Porcelain bases with
large copper movements and contacts. They had been removed from old houses.
A bit of cleaning
and they worked fine.
The problem I encountered with ladder line through the wall and into the
tuner was RF.
It was everywhere. Stubborn, too. Would not go away until I found a
current balun,
mounted it about 6 feet from the shack then ran RG-8 Coax to the balun and
through the wall.
The Omni 6 was fine, but the RF gave the computer a fit.
