I tried e-mail but it came back.

Are you sure it's Mackay 3041 and not a McKay Dymek 3041?? If so that could
be a real fine piece of gear, they made a MW receiver but they don't show up
very often. I have the McKay Dymek DA5 (there is one on ebay right now)
ferrite bar antenna and you couldn't pry it out of my hands. If your party
has the antenna that goes with it, grab it if price is any way near
reasonable. Rob Mills
