Hi Graham,

Likewise I still prefer WSPR.

Decodes occur at similar levels to OP2 and the interface and web database features make it the more attractive mode, for me. I'll continue to play with both though and make a more informed view later. The OOK feature of OPERA I can see is attractive for many.

Hope to be QRP testing again this evening, probably TXing on WSPR and monitoring both WSPR and OPERA on 500kHz USB dial. I would like to find out if GM4SLV can decode me on either mode using my current set-up. Will you be around John P-G?

Graham,

Regarding your dual mode 500 kHz tests yesterday. For me the absolute winner is WSPR, when Opera stopped to decode, due to QSB, WSPR continued with decodes at least 3 to 4 dB deeper into the noise.
