Opera digital mode. The new software by EA5HVK, Jose Ros for QRSS on Weak signals

Opera is still in Beta test, the latest version is V.1.8.8 (Download from Link below!!) – The new “Opera” Single carrier Data/Beacon mode Tx/Rx, is created by EA5HVK, Jose Alberto Nieto Ros, by request of GØNBD for Ham Radio CW Community – This software, complete windows compatible Tx/Rx package with internet spotting and chat facility, COM-port keying and audio tx drive, is free!

The new software “Opera”  Beta, developed by EA5HVK, Jose Ros (author of the now established ROS Data mode!) using DSP techniques, it’s a alternative QRSS for weak signal experiments on 136 & 500 kHz and for HF all bands (80 to 10 mt) for Ver. 1.1.2 up – Better than standard QRSS, similar like WSPR, but with Opera you can choose your own interval time between 1 and 60 minutes.

CAT Link embodied and Tx by COM port Key or Audio drive Tx\Rx COM port switch faclity – Decoder are possible with S/N – 26 to -38 dB (Rx speed auto-selected!)
