I can pick up the Anthorn , DHO38 and GBZ signals in UK but there is 1 more at 22.6Khz Im not sure of. I didnt know what they were till i saw these videos lol. I have a coil of wire fed thru caps into my soundcard (audigy 2 ZS) and SpecLab picks them out nicely :)
In USA zip code 02878 there's a teletype like signal at 306.5kHz and some Morse Code beacons around 380 kHz, and there should be WWVB at 60.0 kHz, but my BT878 ADC can't pick it up, even though my radio 'atomic' clocks can. I even bought a $10 clock just to take apart for the ferrite. I'm going to hook up *that* ferrite and see if I get anything. If I find it in the waterfall, I'll heterodyne it into the audio range and post it on a video.
A couple of nights ago I received an FSK modulated signal at 21.3 kilohertz using a IC voice recorder (Sony ICD-SX700) in Linear PCM mode. I looked at the spectrum and found it on there later in Audacity. I looped a long wire and pointed the narrow edge of the loop towards Fort Collins, CO and was able to get WWVB on the BT878 ADC when I used a Radio Shack Amplifier/Speaker. (that cheap $15 audio amp goes up to 350 kHz!)
It's a shame it's the only Alexandrian alternator left. There were quite a few, I've always wondered what happened to the rest if they were melted down for scrap or something.
It's good someone had the forethought to save a bit of history. Such a thing is rare.
Thanks for posting. I could never copy SAQ because of the noise that low.

Nice.
So you use upconverter by mixing 28 MHz osc ;)
I'ts rigth?
I think we have some QSO on CW

Try next saturday (dec 6 2008) morning around 10:45 UTC. SAQ will be aired again.

Thx mate will do !!

I really envy people who can receive anything but computer and electrical noise that low down. In this area, there's no chance at all.
