@VE2UWY @zazzoo Yes! The U.S. military used to do this as well. (Not sure they still do)
The doppler must be wicked. I have done aurora (for the non ham, bouncing signals off of the aurora. same deal ionized gases)
the doppler on aurora is very bad making voice more difficult to do.

I’m no expert in meteor scatter but AFAIK the Doppler shift is within the pass band overall - there is spread, possibly similar to aurora. Btw I don’t know if people realize there is measurable Doppler on HF skip, especially during solar events, when the ionospheric layers change in height. -

Diane Bruce VA3DB (va3db@mastodon.radio)'s status on Friday, 11-Aug-2023 02:17:50 JST Diane Bruce VA3DB @jmorris @VE2UWY @zazzoo I was thinking of UHF actually. It's a problem for us satellite operators and you can hear it in a car moving. Every done the SSB mode listening to a repeater and hearing the pitch change? It's wild ;) So I figure there is a limited range for meteor scatter as well?
