So it looks like a first peak of strong echoes appeared between 04:00 and 04:10 UTC and a second one between 04:40 and 04:50 UTC.
These data, automatically collected at home with HROFFT + ColorLab will be confirmed or corrected in the next future by a manual count using SpecLab, because it clearly looks like some masking effects and amplitude fluctuations coming from strong echoes totally fool the automatic counting softwares.
The radio station consists in a turnstile antenna, and AOR AR5000A receiver tuned in SSB mode on Nevacerrada TV transmissions (48.250 MHz).
Location: 48° 40' 19" N
