Hello Mr. Hunter,

Thank you for your kind reply.  I have checked the sites that you 
mentioned and have contacted the Western Electric Hawthorne Museum in 
Chicago, where the transmitters were apparently designed and 
manufactured and their Librarian may have some information.  I have been 
in contact with Stan Adams, a former AT&T man who submitted most of the 
Western Electric material to Harold Hallikainen's fine site.  I have 
obtained pictures of the WE 1-A and/or 1-B in ten different stations 
from books and from the web, but only KPO and KFWI were on the West 
Coast.  It is possible that KFWI was using the old KPO Transmitter but 
that is mere speculation on my part..  According to one author, WE sold 
18 Radio Transmitters before 1925, but some of these were smaller than 
the 500 1-A & 1-B Models.

The Radio Historian's KFWI Schematic is the only diagram that I have 
been able to find anywhere.  Only the biggest of the early radio 
stations could afford Western Electric and most of those received power 
increases within a few years and abandoned the WE 1-A, usually moving 
the station to a different location.  This has made any direct 
information on this transmitter a lot harder to find, but I still hope 
that there is a WE Manual for this transmitter out there somewhere.

Thank you and thanks to everyone for helping me with this very odd request.

Best Regards,

    Hello Mr. Duncan,

    Have you searched the web via Google, etc.?  There's a lot of
    information out there. For example:

    http://www.oldradio.com/archives/hardware/WE/1-A.htm
    http://louise.hallikainen.org/BH/index.php/WesternElectric
    This page has a good scan of the WE 1923 Broadcast Equipment
    Technical Bulletin.

            Good Morning Mr. Hunter,

            Please accept and convey my admiration for the fine Radio
            Technology Museum and web site.  I spent a very pleasant
            afternoon at your site and really enjoyed watching the
            demonstration of the Aeriola Jr.  I am fascinated with old
            equipment designs that predated the tube era when creating
            low-loss coils was High Tech.

            I am researching a very old Western Electric Radio
            Transmitter that was manufactured between 1922 and 1925.
              The Western Electric 1-A (or 1-B) 500 watt Radio
            Transmitter was the first transmitter to be manufactured for
            sale on the open market.  In your area, WOR's second
            transmitter was a WE 1-A after it moved to New York City.

            Is it possible that your Club might have any information on
            the Western Electric 1-A or 1-B?  This WE Transmitter was
            State of the Art in its day and apparently WE developed both
            the Hartley Oscillator and Heising Modulation for this
            Transmitter.  I would like to create an electronic model of
            this Transmitter and possibly a physical model for display
            and would appreciate any help or advice that you might provide

            Thank you for your attention and please accept my
            congratulations on a very nice museum and a fine web site.

            With Best Regards,

            H.W. Duncan
