Hello Rik,
Based on my observations frequency shifts 1-2 Hz on 10Mhz are quite common
during sunset and sunrise. During good daylight propagation shifts are much
under 1 Hz via path of 500-2000 km.

Subject: LF: Doppler shift
Hello group,
The question is a bit off topic, so longwave-only readers can push the
delete button now.
A friend of mine is interested in QRSS tests on 10.1MHz (30 meter) and one
of the things we are discussing is the longest useable dotlength is on
that
frequency. Apart from TX (and RX) stabilty doppler shift due to
ionospheric
refections will cause frequency instability.
Does anyone have an idea how much Hz the doppler shift can be on 10MHz ?
Is there any info available on the web ?
