Inspired by the recent burst of Opera-8 activity, I have now started a second correlation detector instance for Op-8:

First hits so far:
2013-08-24 20:37:45 SM6BHZ  1562km 137635.493Hz 587mHz -99.9dBOp  35% 17.5dB
2013-08-24 19:47:50 SM6BHZ  1562km 137635.615Hz 212mHz -36.3dBOp  99% 19.3dB
... apparently the SNR calculation is still not perfectly robust.
 
Opera-32 results as usual on:
 
Now showing R7NT:
2013-08-24 19:41:40 R7NT    2060km 137590.027Hz 120mHz -40.0dBOp  95% 20.0dB
2013-08-24 19:00:00 R7NT    2060km 137590.024Hz 110mHz -43.2dBOp 100% 20.0dB
