... well, I haven't ;-) Out of curiosity, I have instead implemented Guido's excellent guide on Opera encoding 
in a little Basic program, which outputs the 110... keying sequence for any given callsign.
 
And it works! For a quick on air test, I decided to use SpecLab's test signal generator, modulated by an arbitrary waveform which can be loaded from a text file. To fit to the required data format, I edited the sequence by zero-padding from 239 to 256 symbols, then replacing every "1" by two lines of "32767", and every "0" by two lines of "0", giving 512 samples total. For "Op4" speed, the AM modulator period was set to 0.256*4*256 = 262.144 seconds. Audio output was used to key my TX on 478.63 kHz. I sent for strings on Saturday night 21:30 to 21:47, and within a few minutes, pskreporter.de showed spots from DF2JP, G8HUH, ON6EO and DD7PC.
 
In case you would also like to send Opera without "his master's software", or associate obscure received sequences with possible candidates, the little program and sourcecode is at

Hello Markus, LF
i also have not installed Opera software but inspired by your little Basic program i decided ( of course,  just for fun)  to continue with  another "homemade" Opera version.
I have used your  program which outputs a callsign in a form of ascii 010.... as an input for my little Fortran  program which puts RTS ( or DTR) line of a serial comm port
into high or low state with a specific [Opera n = 1,2,4,8,32] duration in accordance with 1's or 0's of the encoded callsign. This, in turn,  keys on/off  the transceiver.
Therefore, i have avoided the use of SL/ modulator etc...  it was too complicated to me at the first sight.. :)    .. and still is!
 
I  put my trx into 20 meters band and today afternoon i've sent few instances of the  homemade Opera - got positive decodes frm RA1AHQ,EA4SWL,F6AVP,IW2OHP
so definitely it works!  Well, very likely , that in the forthcoming looong winter evenings i will  try to reinvent the wheel once again
and following the excellent description of Opera encoding by Guido, PE1NNZ i will write the rest of the  ftn code just to have an 'autonomic' piece of software.
Once again, i know we are doing so many unnnecessary things but.. well,  it was a fun...

qth: Lodz /jo91rs/

p.s.  question:  As i am not familiar with the Opera 'original' software and, in fact, with the pskreporter facility
       how the reporting/monitoring stns got my locator correctly ? is there any 'database' built in ?
