[NJARC] Old Western Electric Transmitter Schematic

[H.W. Duncan]

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,

H.W Duncan
