SNR > reports 3 dB lower than actually present in the signal path. Unfortunately s/n levels are not that simple to determine or set , the original ROS , later Opera mode's where aligned with FLDIGI t
''Apparently Opera is functioning as a beaconing system, and nothing else. You basically transmit one information ("I'm there"), and you get a reply by the internet ("I see you"). Am I missing someth
Hi Graham, LF, wow such a flood of incoming mails... BPSK vs. ASK? Unfiltered PSK _can_ be sent by a nonlinear transmitter, it's only very unfriendly to others due to the spectral sidebands from the
Hi Rik, thank you very much for the link to the results of your study. I was told often, that Opera is much more sensitive than WSPR. It was interesting to learn that this might be the result of Oper
Well its mostly a silly argument as the systems are totally different , in terms of data processing and the operation of the decoder and the technical level of the equipment needed to tx/rx the mode
Never replace the MORSE KEY, you do at your peril !! Other modes come and go but MORSE lives on All Radio Operators know this. G3KEV -- Original Message -- From: [email protected] Markus Vester To
Thanks for the hints, Graham, I will try to keep all in my memory! 73 Sabine, DL1DBC Am 12.09.2012 12:22, schrieb Graham: SNR > reports 3 dB lower than actually present in the signal path. Unfortunat
