Hello Andy, Markus (DF6NM) sent this explanation for the Loran lines which I observed in the AM spectrum: So the 1000.0000 Hz are really there, as "AF harmonic" from Western Russia. I can only confir
Hello group, An update on the WOLF tests on easter weekend: During more WOLF tests (which finally resulted in a 2-way WOLF QSO) with DF6NM, Markus found out what was wrong: It was the TX sample rate
Hello Jim, Markus, and group, Some on-air testing of Stewart's implementation of WOLF took place on sunday evening, which was partly successful (tnx Markus, DF6NM and Jim, M0BMU for their patience an
Hello group, Happy easter to everyone ! Now that my oven-controlled 'master clock oscillator' seems to work, I will try a first test transmission with "amplitude shaped" WOLF BPSK this evening, start
Hi Alan and group, The operator of DL3FDO is Reiner, not Wolf. He lives in the Frankfurt area in central Germany. I guess Alan mixed DL3FDO's call with mine or with DL1SAN who's name is also Wolf (an
Hello group, LF propagation may have been poor this saturday, but there was a phantastic radio aurora on 2mtrs here, even Italian stations were easy to work via aurora from DF0WD (on 2m... would have
Hi John, Same happens here (with ISP=AOL) sometimes. I often experience this: After disconnecting from the ISP and re-connecting, there are suddenly 3 or more new incoming mails. As I don't know anyt
Hi Uwe and group, DJ8WX's recent waterfall image certainly shows the French Navy's signal on 18.3. Their modulation is indeed a bit broader than GBR. For comparison, a small spectrum plot from monday
Hi Alan, Andy, John and the group, Thanks for the quick response to my question about the 16kHz-signal. I must have missed the information formerly posted about MSK on 16kHz on this reflector, but no
Hi all, During some RX experiments in the VLF spectrum a few minutes ago, using a bundle of ferrite rods and lot of wire as antenna. There was.. - a quite strong signal on 16kHz, 100 Hz wide; - an ot
Hello group, The automated RX facility run by Brian CT1DRP works beautiful now, here a few suggestions how it can be used. I tried to be 'heard' by Brian's RX system on late saturday night (May 26),
Hi Brian, I can proudly tell you it was me. Now I'm off to have a look at your pages. I transmitted the signal from DF0WD in the hope that it may be detectable. The QRG on the display was 136.925 +-
Hello group, Because of the coming test transmissions on 16kHz and 17.2kHz, I did a few tests with 'direct reception' of LF signals up to 20 kHz using only the PC, a soundcard, a piece of software an
Hello Group, please forget my last posting to this group. Noticed too late that I received the antenna article from another reflecter. And Guess it was only adressed to the US guys with their antenna
Hi Uwe and Laurie, the reason why Uwe's nice picture of Laurie's transmission looks quite sharp is simply because the FFT length used there is quite low. This gives nice sharp edges of the DFCW signa
Hello Brian, Markus, and the group, I have just uploaded the first beta release of Spectrum Lab V1.65 . There are some new functions in it, most interesting may be: - dynamic range up to 150dB (with
Hello Alberto, Stewart, Walter, and everyone planning to go to the Ham Radio Fair in Friedrichshafen. Some meeting frequencies.. very sorry that 136kHz is not included: 430.025 MHz FM simplex (sugges
Hi John, I would suggest Dave G3YXM's website, because his site has a well maintained link list to all other LF sites, including Steve, Peter and all the others. Copied and pasted from my favorite LF
