Hi Alex,

thanks for clearing up that mistake - s= o the VK4YB spots were also listed wrongly on 137 kHz.  
=
Regarding WSPR-15 vs Opera-32, here are 50% detection thresholds, measu= red with a constant non-fading signal against Gaussian white noise in 2.5 k= Hz:

WSPR-15: -38 dB (carrier),
Opera-32: -40 dB (average) = =3D -37 dB (carrier) ,
Opera-32 dynamic deep search: about -45 dB (= average) =3D -42 dB (carrier),
Opds detector : -48.5 dB (average) = =3D -45.5 dB (carrier), assuming phase coherent transmissions.

Note = that the deep search modes produce only correlation detections no= t decodes 

I haven't actually measured the sensitivity&nbs= p;of the RN3AUS Opera decoder, but I think it's somewhere between Opera and= opds.


Best 73,
Markus
