Hi Markus, Wolf, Stefan, Peter es all,

tks for the advice, Markus

now SpecLab is beaconing in mode Op-4H on 8969=2E99Hz

the PA is off until it is dry outside=2E

I keep your proposal  txing btwn 0700 and 1400MEZ in mind= , Markus=2E

Betreff: Re: LF: Sending Opera with SpecLab

Greetings all,
(and apologies to Markus for juming in so quickly=2E=2E)

The principle described by Markus is only for transmission=2E
To take place of the DS option, i=2Ee=2E 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=2E
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=2E 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=2E

All the best,
  Wolf  DL4YHF =2E

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

Subject: LF: Sending Opera with SpecLab

Today I final= ly found a simple solution to send Opera sequences from SpecLab's digimode terminal=2E 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=2E This seems very useful, especially in the context of possible future VLF Opera transmissions=2E
 
First you wil= l need to create a text file consisting of the 239 bit 1101=2E=2E=2E sequence = for your callsign=2E This can be generated from the PIC menu in the original Opera software=2E Or you can use my little code generator tool at http= ://df6nm=2Ebplaced=2Enet/opera/opera_generator=2Ezip - si= mply copy opgen=2Eexe from the zip and type
 opgen m= ycallsign >opera=2Etxt
into a comman= d window=2E
 
In SpecLab, o= pen the digimode terminal and configure it for ASK with no encoding, as shown in the attached "_settings" screenshot=2E The symbol rate has to be set to the inverse dotlength for the desired Opera speed:
 
mode   d= otlength    rate
  &= nbsp;       (seconds) (sym/s)
Op-8 &nb= sp;  1=2E024s     0=2E9766
Op-32 &n= bsp; 8=2E192s    0=2E12207
Op-4H &n= bsp;65=2E536s   0=2E01526
 
Shaping time can be selected from hard (0%) to soft (50%) keying=2E Then enter your desired audio frequency and use "Load TX text" from the file menue to load your opera=2Etxt file=2E The sequence will appear in the TX window, and the transmission can started by hitting the RX / TX button=2E
 
Best 73,
Markus (DF6NM)
