All,
We have a working version of the Opera beacon , with OP1 and OP2 =
modes based on the 17Khz audio band. noting any version may be =
coded, this represents a first of trial.
The version is fully functional and compatible with the standard =
version in terms of data , so may be decoded via sound-card SDR or =
via conventional translation to base band audio using one of the =
vhf/uhf settings.
At this stage , the file is a separate exe 'Opera Light.exe'
to run the exe , its necessary to install a working version of the =
standard system to provide dll's etc and paste the 'exe' into the same =
directory=20
If any one would like to try the system , I can email the file =
directly , the final version will be incorporated into the main =
download.
As the Opera system is incorporated in Bo's OZ2M fixed beacon keying =
system , Philip Gladstone , psk-reporting map , is providing addition =
SHF bands to his map, and I have requested a 'optical' band be added =
to compliment this addition.
At the moment, please contact me directly for a copy of the exe file =
at g0nbd@hotmail.com

:)
Pre release information=20
=20
OPERA OPTICAL BEACON variation=20
=20
Based on the lecture given by Stuart Wisher G8CYW at the RSGB =
convention , outlining the use of a high frequency audio sub =
carrier for optical communications , where the light source was =
modulated with a 17 KHz carrier to enable various modulations to =
be carrier above the audio 0>3Khz base band, thereby eliminating =
most of the QRM.=20
=20
Following this example , a modified version of the 'Opera beacon' =
is in development , with direct audio input / output based in the =
15 to 17 KHz range , with intended OP0.5 and OP2 modes [ 30 =
second and 120 second tx cycle time] , OP0.5 has been proven in =
scatter tests on vhf and OP2 has similar sensitivity as the wspr =
system.=20
=20
The Opera beacon system is a free running one pass decode data =
system , with no internet time locking requirement , utilising =
On/off keying (ook) of a single carrier , transmitting 256 data =
bits. Transmission either by way of a keyed audio output, as per =
normal data mode soundcard interface or a simple com-port cw =
keyer of an existing 'cw' system , Tx/Rx com-port ptt switching is =
also provided.
=20
Where as the Tx format remains the same for all , the decoder =
has variations linked to the assigned band, propagation and , the =
Tx duration is used to set the sensitivity , with versions from =
30 seconds to 4 hours , -20 dB s/n to -50 dB s/n.
=20
CAT control and SDR interfaces are provided as part of the =
windows based software package , as is a 'PIC Code' , which may =
be used to code a stand alone pic controlled beacon, as is a =
internet chat facility and spot upload to the psk-reporting web =
site , decodes from other users are also directly routed to all =
web-linked users , with single band or 'all' band filtering.
=20
The latest version may be downloaded from http://rosmodem.wordpress.com/
Notification will be posted when the 15/17Khz modem is embodied=20
