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?

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.
