Hi Guys :)
I thought I’d say thanks for the add to the group and introduce myself.

I have a question…
Is the reason most amateur radio people care about accurate frequency mostly
about
operating at higher radio frequencies?
I imagine if a bunch of radio enthusiasts aligned their HF radios
Hi Guys :)

I’m only starting to get compulsive about time and frequency.
My findings so far are that only the timing of the next second matters because
it’s too late
to worry about the current second by the time you have the
Alex, Brek - the Doppler effect is primarily an effect of the ionosphere
moving. A 24 hour measurement of WWV on 20 Mhz shows as much as +/- 800 mHz
movement, all due to Doppler. Note that if you run the measurement over
several days at the same time of year the measured frequency will strongly
Hi Brek. In my experience the perceived frequency difference from Doppler
shift is of little or no relevance for amateur HF communications. For
amateurs involved in activities such as the frequency measurement test I
believe it could be at times relevant at HF. There might be a mode where

Not exactly Brek, as long as the position of the two stations, which are
in contact with each other, does not vary in the time, you don't have to
worry about Doppler effect, also if you are trying to get in touch in
SSB mode in the 13cm band, you rather have a precise frequency
reference and
