PS: Jay, Markus, What is the S/N performance of OPDS compared to WSPR-15 (apart from the fact that the callsigns must be known in advance and that there is less information into one sequence) ?? 73,
Hi John, Jay, Markus, OK. Well, it seems to work. But i can't value the results. Why is it only 96% and what is the meaning of 2 mHz here? Seems the S/N is rather low. Condx must have been poor. Were
OPDS T/A enthusiasts Stefan, here's my copy from last night. Missed the first transmission not knowing you were on the air. John managed to snag the earliest transmission and one more decode late in
Stefan, Jay, John, the "96%" number shows the temporal overlap between the receive period (ie the duration of the currently used FFT, about 35 minutes) and the identified Op sequence (33 minutes). Wi
Both ROS Hf/Mf data modes and Opera , s/n measurements use the path-sim simulator as the calibration reference , which is higher than the levels produced by fldigi / wspr etc , ie transmission needs
T/A OPDS enthusiasts It appears that I mistakenly ran with a known setup issue last night ... so my reported SNR numbers should not be considered accurate. The issue is now resolved and the setup is

Jay, John, LF, ...so it is another OPDS32 night? Or are you prepared for both, OPDS32 and OPDS8 ? 73, Stefan Am 18.10.2013 23:43, schrieb John Andrews: My setup is running, but I can't check or modif
Markus, Wow, somehow genial! Where did you learn to make such a program? Thanks for the explanations. What is the next challenge? WSPRDS?? Isn't it possible to correlate WSPR signals as well? 73, Ste
Stefan, thanks for the flowers. WSPR correlation? In principle, yes, but... http://uk.groups.yahoo.com/group/rsgb_lf_group/message/3207 Good to see you on air! Opds has identified your signal already
Stefan Wasn't expecting you to start transmitting OPDS today ... just a thought for the future. But if you want to, that's okay too. OPDS32 is capable of of decoding at about -50 dB s/n (relative to
Hi Jay, Group, Lately, I've been busy trying to rx below 100 kHz with an old Marconi XH100 receiver. One of these ebay chinese DDS boards was used to provide the LO, but it was not stable. The 10.7 M
Hi Jay, I wanted to give it a try tonite. First i wanted to use DF6NM's OPDS software which i would really prefer over the ROS-OP stuff. But then i found that the sndoutpt.exe creates a ramp in the a

Jay, Correction: Markus created a special file for me which makes the ramp time shorter than 1 ms. So now my PA can send OPDS with Markus' software and i am on air in this mode tonite until 06:15 UTC
Stefan Surprised at poor s/n (-46 dBOp) on initial decode ... maybe we're in a fade. Progress monitored at : http://www.w1vd.com/grabber.html Jay Jay, Correction: Markus created a special file for me
