I'm afraid that 640khz _is_ the correct lower

Somewhere, buried in some archive, the developmental
documents for Conelrad may still exist and may explain
the
choice of frequencies. I think mostly it was to have a
frequency that would be usable for any BC station. I
also
don't remember (if I ever knew) the power stations were
supposed to use, I think quite low, perhaps a couple of
hundred watts.


640 was VERY vacant in those days and 1240 was very full.
I think the
mindset was to cover both extremes but thats only a guess
on my part.


Depends on where you were.

KFI in Los Angeles (actually La Mirada) has been on 640
since 1922 and
running 50 KW since 1931.

KFI was a Class 1-A clear channel, not duplicated at
night and with few daytime only stations on the same
frequency and those located in the East.
KFI was the key CONELRAD station in LA. It is one of the
very few stations to operate on the same frequency as it
started on. KFI's original studios and transmitter were in
the Earl C. Anthony Packard dealership at 1000 S. Hope St.
(10th and Hope) this had the original flat top antenna on
top and I believe the original 5KW transmitter was
maintained as an emergency transmitter until ECA's death.
La Mirada is a fairly recently established city. The
transmitter location used to be given as "near" Buena Park.
I it when it was in the sticks, mostly dairy and truck
farms.
