Surely, Graham, this is dependent on the terms of whatever licence
the IP is released. It might be relevant to argue these matters
against the terms of the various GPL that have been defined. Richard
Stallman presents some good arguments that are particularly relevant
to Open Source etc.

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 .

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.
