I'm afraid that 640khz _is_ the correct lower frequency.
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.


You are right. That's what happens when you depend on memory. Sorry
for the error.

Memory? What's that?


I dunno. The other half says it's the second shortest thing I have. I
forget what the other thing is....

This should bring back some memories for those over '50' here.
