I missed Saturday morning's transmissions but managed to record both hours this Sunday morning. Like Luc I could only barely make out a signal on 6.7925 but heard the signal on 7.4075 MHz more as continuous signal. By my ear I could not distinguish between a ground wave and the moon reflected wave, if there was one. I recorded the listening sessions using HRD and used a 10-Mb file size limit and I went to bed around 15-minutes into the 7.4075 transmission. My setup is modest; an FT-817; ~100-ft RG-213/U to a Butternut vertical. There was considerable noise ranging from S5 to S9.

It is 0436 am and i recorded about 5 meg near an hour of only one signal on 7.4075mhz. I will have to listen the whole recordings and recheck them with spectran to see if this signal was coming directly from the Moon or from the
HAARP site in Alaska?
I barely guess the signal on 6.7925 Mhz but on 7.4075mhz spectran measure a noise floor at +_ -50db and the signal was around -30 db and curiously without the fast fading present on the other broadcast stations around.
I don't believe an echoed signal from the moon can return back through the ionosphere when the propagation seems to be rock solid at that time on a very near 40 meter band frequency!
But the experts will probably give their own opinions? And for those who can get an 1.8 meg .WAV file on their mail server box, i can send you a short piece of my recordings
