I'm KE7JA..... not KE7JGB anymore. Nor am I Chet, K7JA, although if I'm
not careful how I pronounce "KE" it comes out "Kayeee" instead of
"K...E..."
If you use a vacuum a "mouse" can be sucked a long way through conduit.
Simply make a cloth "ball" and tie a light line onto it. Use your shop
vac to suck it through the conduit. BUT, be sure to put a screen at the
end of the conduit or the mouse will end up inside the vacuum.
