5meter radio, AMRAD: A History Question

[Frank Gentges]

Michael,

AMRAD is a club of radio amateurs that was formed in the 70s.  There was 
a manufacturer by that name in the pre-WW2 era that made some of the 
early battery tube radio receivers.  I suspect that company is the one 
you are interested in.  If you look at books on antique radios you can 
find AMRAD radios listed.

The 5 meter radios are a bit more advanced than the ones I have seen 
listed.  I suspect that AMRAD suffered the fate of quite a number of 
radio companies in 1929 as the economy did not support the more 
elaborate high end equipment and went out of business for lack of paying 
customers.  You should research this line and see just what did happen.

Take a look at Antique Electronic Supply, http://www.tubesandmore.com/ 
in their books on antique radios.  I think I saw some stuff in one of 
those books but don't have them to check.  You may also want to contact 
the Antique Wireless Association as their members may have some information.

One of our members, George Lemaster, has attended AWA meetings and may 
also be able to help.  Go ahead and jump in George.

Good luck in your quest.
