Re: LF: Opera-8 and -32 correlation

There must be enough  'spikes'  in the  pc Markus   to  make a  cactus !

 

Amazing  results  these past nights  since  Gus  , started  op8  , is anyone  running  the

correlation  in the  USA ?    may op8 would  show  up ?

 

The  new  75K band  , has  Opera    16  and  64  allocated

Subject: LF: Opera-8 and -32 correlation

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
