I have run both together. If OP alone don't make it after -40 the DS would.  It simply works-your talking to me-a user of both time and time again.  There are nights OPDS isn't needed and other times my signal ain't quit makin it.  OPDS makes me look good those marginal nights!  It's still OPERA but just "spruced up" a little-how bout that?

That's  two different  shows,  
 
When it  comes to  the numbers  then  things  can go  wrong , the  best  way  is to  run the  two  up the  strip  together ,
 
The  best  way to  detect  a  carrier , as Stefan will  tell  you  is qrss   as you  can  wind the  time  out  as long as you like , then you
need  to  be  stable  , each end etc

G;
Myself I don't care about source code, don't know what it is-don't want to know.  It's your secret that's fine but if you can add something that under adverse conditions can make the difference in decode-correlation or whatever you want to call it, I want it.  Save me from building a 10 times bigger transmitter, substantially lower antenna voltages for the same decode-I want it!  I guess it's an ego thing as someone else would get credit for your development of the basic working  system.

Its  the old source  code  argument
 
There are plenty of  locked  systems  in use , source code comes under  'IP' Intellectual Property rights , there is no  need  to  disclose  as  long as  all  can  use  the  same , sure  some  would  like to  see  'how'  but that's another angle  , same  with  encryption, DSSS numeric based data  modes like  Olivia , chip64, contessa , ros hf   as long  as  the  software  has the  same  keys  then that  meets the  requirements
 
The Opera  decoder is  a  data  decoder ,  Marcus is  running  correlation , pattern  matching , two  different things entirely , one has high  equipment  over heads , the  other  uses anti noise/ fec/afc  software routines to  negate hardware affects on system performance and counteract propagation conditions , Opera  is a  averaging  system and  requires  for a decode , the  average  of  the  min s/n  , from 50% of the  data  randomly dispersed along the  time  line , ie first 50  last 50  or  any 50%

What your saying is for those of us wanting to improve things go play with the other systems and leave OPERA just as it is? Bob

There  are plenty of  commercial  data  mode  systems  in use  on the  Ham bands  that  are locked  and not  publicised , from  my experience , the  locked systems seem to  give a  superior level  of performance  to the  open    code  versions , pactor-4  being a  good  example , using  modern  ss techniques  achieves  high data/power  ratio , but  missing  is the  cdma  layer that  would  enhance  b/w  user efficiency  , but  that  exists in another locked data  mode , which is  free
 
So  where /what  is the  problem ?

Thanks for forwarding the message Bob - so I won't spend any effort in implementing Opera myself if Markus's DS algorithm is really embedded in the Ros-software.
Despite the fact that I don't like, and will not use, the original Opera software myself as long as its author makes such a secret of it, leaving it to others to reverse-engineer the algorithms.

Cheers,
  Wolf .

Especially #1!!!  If that alone could be accomplished the rest later would do just fine. Bob, WG2XRS/4-4000 meters, WE2XEB-2200 meters, WE2XGR/6-630/600 meters-W2ZM...

A few thoughts for Opera enhancements VLF to 160m

(1) Deep Search Detector built in to existing Opera system with ability to run alongside existing
Op decoders and report directly to PSK reporter

(2) Reinstate the dual receive function without having to open multiple instances of the software.

(3) Dynamically resizable screen or replace the dials with led bar type indicators - would make
the overall screen size a little smaller.

(4) Option to "tear off" the waterfall to enable positioning on another part of the monitor screen -
like wsprx for example.
