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
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
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
Hi Stefan, how many turn in your hoola hop ??? My preamp with OP27 works well for SAQ reception with 40 turns hoola hop , but for 8900Hz ?? 73 Mauro IK1WVQ I just built the preamp of Renato Romero's
Finally my prayers were answered! Thanks to the God of the RF! (my RX needs a longer break .. say few months ????) 73 de Mauro IK1WVQ, with his rx continuously intermodulated ... P.S.: what kind of i
unfortunately I do not know the ansver to your question, but I am VERY interested on this kind of antennas for my 137 and 500KHz rx .. please, how big are the "probes" ??? Is this antenna also usable
At last!! Seemed to read the endless acts of the Italian Chamber of Deputies! thanks to all! Mauro IK1WVQ At 14.26 28/05/12, you wrote: It's interesting to see how smoothly the migration has taken pl
Hi Graham, yes, sorry, I wrote a code for a small PIC processor and that was the first decoding test! OPERA is very indiscreet !! ... And it is impossible to stop sending spots on internet without de

Hi to all, it is true what OPERA mode is "secret", but, I think, it is better than WSPR for semplicity: on-off carrier , no time synchronisation required (then it is possible to made a simple beacon
hi, "simple" = - modulation ON-OFF , no needs for linear P.A. - no precise timing (= little beacons stand_alone. no PC.) - TX only 50% on. (to take in mind when compare whith other "continous" mode a
Hi to all, only a question to the experts: is the SLOW WSPR better than the simple OPERA-32 ??? 73 de Mauro K1WVQ At 16.57 22/09/12, you wrote: Hi Markus, LF, It works! First reception of DF6NM in WS
Hi Stefan, what DIAL frequency must be set in RX for receive your WSPR packets ??? 73 de Mauro Ik1WVQ So now i joined the WSPR group and start to do some test transmissions with the normal 2 minute W
