I’ve been monitoring the Doppler shift of WWV/H and CHU for a while now from my
location 100 km / 60 mi NW of Seattle.
The receiver is a QS1R, using an LTC2208 16 bit ADC, and the 125 MHz clock is
provided by a Bodnar GPSDO. A Wellbrook ALA1530S+ loop antenna provides good
coverage for the e
Tom: Thanks! Rob: your toolchain (to borrow a phrase) produces great
results. If I read the graphics right, you might be able to obtain some
outstanding results from the HAARP Research Campaign 29 Nov - 03 Dec

I used to measure WWV carrier only (a much more pedestrian approach than yours)
with a qs1r locked to a Valon synthesizer driven by a a very nice (for my
budget) 1000A oscillator that Corby provided me.
I often saw (now I could be reading your data wrong) a minimal shift when the
signal strengt
I think I've seen something similar during and after geomagnetic storms -
weaker than usual signals, but very low and steady Doppler shifts. It will be
interesting to see how things change when solar activity increases.
The QS1R is a great receiver. Even with the original TCXO I could see WWV
