It can be reported like CW and QRSS beacons by posting via
Blacksheep with email attachments if required.
or even better REAL time reporting in QSO mode --- No need
for PC or database storage/reporting.
I receive Opera to check my RADIO but disconnect the
internet modem because I do not want the data base information
I also transmitted Opera QSO mode on 500 and got no
replies although I got reports from all around EU via direct
emails, seems QSO mode is not popular

All,
Who is still receiving and
reporting at the end of the day. If we all start building smart PIC and other
means to generate Opera.
Do I miss something here, or are that only the
stupid ones that use a PC to generate/receive and report Opera ?

Hi All
Why lock up a PC to beacon Opera? I use G4JNT's excelent PIC
progragram. He supplies the Hexadecimal code for you to program your own PIC
which gives you just that little bit more satifaction in building a PIC
based project.
It is easy to build has full OP modes and sensible and adjustable
interval timing, no bigger than a matchbox!.

... 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

PE1NNZ seems to have demistified the opera
coding, those interested can read the attached file.
