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 2014-11-16 15:42:50 UA0AET 4175km 137512.208Hz 4mHz -42.9dBOp 90% 17.5dB 2014-11-16 15:42:50 UA0AET 4133km 137512.282Hz 8mHz

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
