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?
