Uwe,

I'm only able to decode Op-4H in default OPERA 8.0 KC range with the program OPERA.
So I can only show U how OPERA looks like outside the theatre at www.qsl.net/pa1sdb when you'r not inside the default OPERA 8895 - 
8925 KHz range...

Peter, PA1SDB

  Hi Markus, Wolf, Stefan, Peter es all,

  tks for the advice, Markus
  now SpecLab is beaconing in mode Op-4H on 8969.99Hz


  the PA is off until it is dry outside.

  I keep your proposal  txing btwn 0700 and 1400MEZ in mind, Markus.

  Greetings all,
  (and apologies to Markus for juming in so quickly..)

  The principle described by Markus is only for transmission.
  To take place of the DS option, i.e. for RECEPTION, spectrum lab would have to modified to some extend, last not least it would 
need an 'automated' method to build the correlation patterns for the DS mode itself.
  Since Markus has already provided his opera generator (thanks for that!), it could be modified into a command-line driven tool 
(exe or dll) which SL could invoke to create the 239-bit message pattern for the correlators. I cannot promise too much yet (being 
busy from too many other projects) but maybe  when the new 'super-linear', moderate-power, switching mode amplifier is finished I'll 
have a look at it again.

  All the best,
    Wolf  DL4YHF .

    Markus;
     Can this take the place of DS option used with OPERA?

    Subject: LF: Sending Opera with SpecLab


    Today I finally found a simple solution to send Opera sequences from SpecLab's digimode terminal. The nice thing about this is 
that you can use all of SpecLab's powerful functions, like samplerate correction, adjustable pulse shaping, or high audio 
frequencies. This seems very useful, especially in the context of possible future VLF Opera transmissions.

    First you will need to create a text file consisting of the 239 bit 1101... sequence for your callsign. This can be generated 
from the PIC menu in the original Opera software. Or you can use my little code generator tool at 
http://df6nm.bplaced.net/opera/opera_generator.zip - simply copy opgen.exe from the zip and type
     opgen mycallsign >opera.txt
    into a command window.

    In SpecLab, open the digimode terminal and configure it for ASK with no encoding, as shown in the attached "_settings" 
screenshot. The symbol rate has to be set to the inverse dotlength for the desired Opera speed:

    mode   dotlength    rate
              (seconds) (sym/s)
    Op-8    1.024s     0.9766
    Op-32   8.192s    0.12207
    Op-4H  65.536s   0.01526

    Shaping time can be selected from hard (0%) to soft (50%) keying. Then enter your desired audio frequency and use "Load TX text" 
from the file menue to load your opera.txt file. The sequence will appear in the TX window, and the transmission can started by 
hitting the RX / TX button.

    Best 73,
    Markus (DF6NM)
