Mauro did ask ' the better digital mode ' as "reverse beacon" and listed 3 modes. I think this relates to internet linked s/n reporting systems , as wspr / lentus / Opera and other's that have web li
Hi Peter, yes, I read your experiences .. My antenna was already powered by battery .. I think my problem is noise captured by coax, or noise generated locally and then impossible to distinguish from
Hello Mauro, Did you take notice about my experiments regarding feeding the antenna with a battery ? Take a look at the pictures around the 25th of March in that log: http://www.qsl.net/pa1sdb/Experi
O.K. Mauro, Let us know if you found the sollution in your noisy case :-) 73s, Peter - PA1SDB Hi Peter, yes, I read your experiences .. My antenna was already powered by battery .. I think my problem
Hi to all, thanks a lot for all the answers to my question ... I want to precise my position: I manage a 10.140MHz QRSS grabber from 2 years. This winter I discovered the PA0RDT antenna, initially tr
Ok Andrea, Op simply (ish) uses time to determine the s/n level , by virtue of the power / time .. the time's in data terms are very long , but as compared to existing systems is a improvement .. For
Hi, what is the better digital mode for starting listening 137 KHz band as "reverse beacon" (no TX)?? ("better" = greater number of active stations in Europe) WSPR ?? LENTUS ?? OPERA ?? what frequenc
Just one or two thing's to check The S/N readings produced by Opera are referenced to the SIM - PATH software , so s/n levels shown are calibrated to a different standard The original system was cali
Hi Mauro, At the present, I think Opera is the most widely used. WSPR reaches -27db, not enough for covering long distances on LF. So, it's rarely used. Opera and lentus perform better: Lentus reache
Mauro Yes there are lots of signals in the shadow's of the 'Neon Light's' hihi You can check activity on the psk reporting system http://pskreporter.info/pskmap.html# mode by mode One of the modes ma
Hi Mauro, Am 26.04.2012 18:27, schrieb IK1WVQ Mauro: Now in the 136.170 segment i receive ONLY DK7FC , with good signals but with deep QSB .. Now in the 137.700 segment NO ONE received station ... We
I know for sure that lentus and K1JT's modes are comparable. They both use the "stadard" definition: signal power/noise power over 2500Hz band/signal In my mind roughly : Opera2=WSPR, Opera8=WSPR-6db
Hi Mauro, I am not sure you are asking the right question. Do you think that digital modes will give you better reception or more stations than QRSS? If you can't receive other QRSS stations, you may
