Opera, WSPR and QRSS

For two weeks now I am testing Opera, a new digital mode, developed by EA5HVK, the man behind ROS. It is similar like WSPR, it is not a qso mode but a beacon with slow CW. First meant for low frequencies like 136 and 500 KHz. But with the latest version v 1.1.2 is also possible 80, 30, 17, 12 and 10 meter. Popular frequencies are 30 and 80 meter. The interval time for WSPR is set, but with Opera you can choose your own interval time between 1 and 60 minutes. Because the mode is in an experimental phase, software updates are almost daily. Results are quite good. I think a little bit better than WSPR. Decodes are possible with -33 db. The old way of QRSS was a struggle. I have never been reported with QRSS! Always in vain transmitting a signal. But with Opera it is fine business. Spots are visible with PSKreporter and Hamspots.com. I saw a test with a few milliwatts: 32 million miles per watts is accomplished. Wow! I hope that Opera will be a QSO mode as well in the future.
