[Lowfer] Skywave frequency shift

[W4DEX]

I've been monitoring the second harmonic of 950 kHz AM stations on 1900
kHz.  All during the day, I see a near steady in amplitude and frequency
carrier from what I suspect is from WORD in Spartanburg SC that is 93 miles
to my west.  During the morning hours and back again in the mid afternoon
hours I receive a signal that is slightly higher in frequency and with what
may be skywave distortion.  Just wondering if this may be from WWJ, a 50 kW
station near Detroit MI 492 miles to my NNW.

Remembering the good old days when WSM and KFI had crystal oven oscillators
:)
