"During the experiment, which was carried out on Oct. 28 and 29, 2007, the
radar signals from HAARP were at 7.4075 MHz and 9.4075 MHz"

I do not know the distance to Moon on that days but for the mean distance
384 000 km the speed is:

384 000/2.4 = 320 000 km/s.


Should be 2x384 000/2.4 = 320 000 km/s.

Speed of light is 300 000.

But long waves travel quicker in glass. Would be the same in space?

i'm glad you checked their calculation and found that obvious error...
i guess all the other radar calibrations in the world have to be
changed to account for the bialek speed effect... i wonder if that
would get you out of a radar gun speeding ticket?

Did you communications via Moon?

I have, at another amateur's station, on 432 MHz. Surprisingly the
speed came out almost dead on 300m/microsecond. Used .wav file
recording of transmit and echo and a good sound file editor with
sub-millisecond resolution when zoomed.
