Is it possible to establish the "effective sensitivity" when comparing Opera against WSPR, QRSS3, 30 etc? I am unsure if the bandwidths of the modes in which the S/N is shown for Opera is comparable.
Ok Roger The tx time is linked to the mode name OP2 = 2 mins , OP15 = 15 mins OP8 OP31 mins Who's on ? Yes p possibly , but that would need a web programmer .. but it

Hi Graham, Does Mr Ros have a web presence, I mean like Wolf and Alberto? If I was writing all this neat Opera stuff I'd want to bang on about how good it was ;-) 73, Dave G3WCB IO91RM --Original Mes
Opera 31 has 8 second symbol periods, so has a noise bandwidth of 0.125Hz. Normalising this -38dB (in the ref 2500Hz) to the actual bandwidth gives a S/N of +6dB WSPR and JT4 when normalised in the s
That's ok Roger .. Rx speed is automatic ..... the speed select is for Tx only - mode select via frequency band No PC time lock required ...its free running OP31 expected round -38 dB s/n (ave) OP8 ~

You mean the 'Phantom of the Opera' ? hih Its only supposed to be in beat test , but that seems to of slipped slightly .. I think there will be a site ect , but he is waiting till the system is stabl
Somewhere I must have missed some information: How long does it take to send a beacon message in Opera8 and Opera31? Is it possible to have something like the WSPRnet database showing stations on eac
