Hello Alberto, Vittorio, and group, Curious as I am, I immediately installed the brand new Spectran V1 b106 this morning and was amazed of the performance and stability of it. Whatever I tried, I did
Hello Geri and group, Maybe one reason why the MW car radio can be easily obstructed by highway bridges is this: Think of the telescopic car antenna as a purely capacitive "E-field-probe". The E-fiel
Hi Bernd and the Group, I also found the mentioned program some months ago but my old PC had some problems running it. As I see it, the most interesting features including denoiser and narrow band fi
Hi All, just a quick reminder of the VLF-transmitting satellite transmitting on 5,7,9,11,13 and 15 kHz, as John 'CNN wrote. This evening (Nov 27), the sat should be at 50.55°N, 13.43°E on 19:34 (gues
Hi All, Just watching SM6LKM's QRPPP transmission on 3593.53X kHz, fine copy now (the "6" started at 00:01:00 UTC) and: Now someone seems to answer, looks a bit like DFCW but the other signal is too
Hi Johan, thanks for the nice experiment, though I had no success to receive the QRPPP beacon on 80 meters yet. Maybe the time-of-day was not optimal. Does the beacon run 24 hours a day ? -...- Apart
Hi group, I received this from the Amrad LF mailing list, posted by Stewart KK7KA ([email protected]). Hope the HTM format is not a problem for your browser: Hi all, Jake's post is quite exciting; it wo
Hi group, I found this interesting mail on from Amrad's LF mailing list ([email protected]). A bit 'hi-tech' but definitely not 'off topic' .. 73 Wolf DL4YHF. <-- beginning of original mail by Jake Brodsk
Hello Jim, Brian, Stewart and the group, First of all thanks to Stewart for the excellent explanation of the stable signals on 136.00 kHz (received it too late to check the next harmonic of 8kHz but
I saw the same and first thought the same. But the reason was Mal switched to "almost normal CW speed", which broadened the signal (so it almost wiped out DF6NM here, but I used a loop which favours
Hi Fabian, sorry I received your info a bit too late. All I hear on 1843 kHz now is a funny "garbling" noise which has been there for ages. Different subject: The display around 135.92 kHz last night
I tried the same and it worked nice, thanks to Markus' nice fonts. It is very important to set the parameters as explained, especially the "Size" parameter in the font selection dialog. Otherwise wi
Hi Andy, Solid copy here, despite heavy local noise. Using a small ferrite rod antenna indoors. I have not 'decoded' the message yet, the transmission seems to have stopped near 18:50 UTC, or my neig
The 2FSK-Signal centered on 137 kHz with 75 Hz shift also very strong in DL yesterday evening. It is really FSK modulated, not PSK, as can be seen on a very fast scrolling waterfall display. But no c
Steve and Alberto, in fact there is a bunch of Ring-0 drivers around to do the job. I used one by Yariv Kaplan called "WinIO" which came along with all the sources and an interface DLL around. It doe
Hi Andy, Rik and the group, I tried to catch a glimpse of Andy's test transmission but the neighbour's TV, SMPSUs etc were too strong. Just a frew weak traces when the worbly humming carrier was away
Hi group, How about using a simple AD9832 DDS programmed directly via serial interface from the PC, and -if necessary- a PIC to convert standard RS232 frames into the DDS's format ? Johan (SM6LKM) ha
Using a spectrum analysis program to observe weak normal CW signals ? As I see it, using a spectrum analysis program with waterfall display does not really help to copy weak CW signals at conventiona
Hi Mal, if Alberto is right and the W&G 12 really has an IF output in the 10kHz range, it is indeed possible to do the last "demodulation step" completely by software. In fact, you can use Spectrum L
