Umm, don't forget the entire west coast and southwest :-) The old
Intercollegiate Broadcasting System recommended that its member carrier
current stations in the east use 640, except in areas where there was an
adjacent-channel problem with 640. Aside from Akron, Ames Iowa, and Norman
OK, the only station on 640 in the US in those days was KFI. KFI was a IA,
but its signal did not really reach east of the Mississippi. except as a DX
catch. The low dial position was good for the unlicensed carrier-current
stations because the distance they could legally radiate was a direct
function of the wavelength, and the lower the frequency, the longer the
wavelength. 540 might actually have been better than 640, but it wasn't
until later that US stations began operating on 540. Also, since 540 was not
a US clear channel, there was greater likelihood of interfering with a US
station than there was on 640. When WHRB had a carrier-current AM. didn't it
operate on 540?
