Funny things these  dB's  , bit like how long is a piece of string ? 
If these  are the  same tx  , there  is   10 dB  difference in the  same  area ? 
-34  dB decode  by  Opera  is a  substantial  signal [ on 136 !] , Op s/n is  also  average over the  full  tx  time  line

Hi Domenico,
 
yes these are valid identifications. The 15:42 transmission from UA0AET was simultaneously detected by UA0SNV, JP1ODJ and JA8SCD, but you were the only one who managed to pick it up in Europe.
 
Yesterday night, adding LA3EQ to the MF opds-8 search list produced an uninterrupted series of detections between 0:51 and 6:09 UT. 
 
All the best,
Markus (DF6NM)

GE LF and all,

here a list of correlations for opera32 signals received in JN80NU.
There is  a good correlation for UA0AET and UA4WPF and seems they are
genuine decodes.

quasi-Grabber will be active until tomorrow morning
