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 u

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 E

Hi Graham and LFer, I think O_P_R_A_ moderates it`s SNR, but WSPR express radically it`s SNR when if there is thunder spike. For reference, following is my record with UA0AET; (all of OP32 decode) 20
