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
Fred Osterman's book shows ITT-Mackay Marine as being a high-grade military
manufacturer, with a big presence in the pro marine market (now they;re out of
the ship radio business).
mcKay-Dymek was a CA based manufacturer which made interesting radios (some
with Collins filters) which were to be home units..expensive, and with good
audio quality, but not truly prograde.
I've had several, and have nothing bad to say about them. They are covered in
Fred's book too.
Might even be on Fred's website
www.dxing.com but didn't check.
mcKay-Dymek was bought by Stoner Communications (in the Northwest WA or OR),
and all they make now is the DA-100 "active antenna". It's pretty good.
