I was glad to hear SAQ once more on 17.2 kHz at 08:00 UTC on December 24, 2014. I used a Perseus SDR received and a vertical antenna. Signals were weak and readable. I also have a WAV recording but i
Hello, I have the pleasure to report successful reception of SAQ transmission on July 3, 2011, between 08:48 (VVV DE SAQ callup) to the end of transmission at 09:07 UTC. I used a modified BBB-4 VLF f
Hi LowFERs Excellent signal from SAQ today, 0840-0909 UTC. I used the same setup as last July, a modified BBB-4 and SM6LKM soundcard VLF receiver. During the long dash sent before the message, SAQ wa
BTW, some time ago I made a "super rod" which I intented to use for NAVTEX on 518 kHz, as the electrical noise at my location is very high. It consists of seven 200x9.5 mm rods in heat-shrinking tubi
Not all of us are "serious LF DX operators with QRO in mind". I have serious space restrictions and can only experiment on LF reception, and even then with some difficulty. Costas SV1XV -- PGP key: 0
Can anyone give me some advice on the suitability (or not) Hi Roger, I recently tried to use an Acer Aspire One with the SM6LKM SAQ-Rx program for 17.2 kHz and discovered that the built-in soundcard

Yes, Joe, I heard it on about 18.1 kHz, it was actually using F1B mode (FSK Morse code). The signal on 18.3 kHz was also strong. The two signals show as a double peak on the spectrogram: http://www.
Hi, I managed to receive excellent signals from SAQ using my portable setup (laptop soundcard and modified BBB-4 front end) at Psachna in Central Evoia, Greece. A spectrum capture is available at: ht
The don't, they have switched to all these heavily automated and integrated earth and satellite systems, because good radio officers were scarce, difficult to train and expensive. 73 Costas SV1XV

Hi Lars and the Grimeton group! I report that I just heard the Christmas Eve SAQ transmission on 17.2 kHz. The signal this time was weak and suffered from urban noise. I used a 7 m vertical antenna a

Hi lowfers, I was glad to receive SAQ once again on June 29, 2014. I first heard it at 08:40 with VVV marker and 09:00 with the greeting message on 17.2 kHz. The signal was weak but with good signal-
