In this video I had not putted any antiparallel diode to prevent the soundcard from being damaged by excessive voltage input, but I strongly recommend that. It is good idea to connect the antenna to one input channel (L or R) and then, select "R-L" option in the software. In that way, you can cancel the RF noise coming from the PC or from the electric installation in the house.
My sound card can support up to 192 kHz and usually it can receive JJY 60 kHz from Japan (weak) during night hours at my location in southern Malaysia using approx. 30 metres of crude long wire antenna connected to my HP computer running Vista with SDRSharp. Maybe I'll try to receive DCF 77.4 if conditions allow. Cheers and 73!
Hi Mile, Is it possible to receive signal in your location from Cutler (24.0 KHz), Maine, USA using this system? Thanks for the very nice video. Regards. Alexandre.
Has anybody tried connecting soundcard balanced input directly to the ground using probes and looking/listening for earth based transmissions or electricity distribution noise currents ?.
I have AC power lines and an AC transformer outside my house and they do not cause any problem when I am listening using a 160 metre band long wire antenna. You can see the AC on 60 Hz on your VLF (0 to 22 KHz) receiver when you listen near 60 Hz but it does not interfere with the stations operating on other VLF frequencies as shown in this video.
Hi Bert Isevil, I am using PA0RDT Mini Whip Antenna (with J310 and 2N3866) in this video. Here is some very useful links: dl1dbc.net/SAQ/Mwhip/pa0rdt-Mini-Whip.pdf dl1dbc.net/SAQ/Mwhip/Article_pa0rdt-Mini-Whip_English.pdf See this also (for power supply - Power inserter): carconline.blogspot.com/2009/05/pa0rdt-active-antenna-continued.html I am using many ferrite toroid cores in power supply lines and coaxial cables, as you can see in my video here: ua-cam.com/video/_3BN1X8cijM/v-deo.html.
I must be about 10 years too late to get any of this to work! Do you think there is a version that will run in Win10? I've tried both SAQ_v094 and SAQrx06 but they both give an error saying: "Invalid Number of Channels".
Masereka Moses You can download the software from this link: sites.google.com/site/swljo30tb/ There is even better solution for receiving VLF with PC. Look at my other video with SDR# software. You can download SDR# here: sdrsharp.com/#download 73 ! Mile, Z33T

Give it a try with SDR# and the "Sound Card" input. You will have more filtering options.
It is good idea! I will try it! Thanks.

Thanks for the information. Try with Mini-Whip active antenna. It is great for VLF.

Was it a PA0RDT Mini Whip that you used, or different one ?
Has anybody tried connecting soundcard balanced input directly
to the ground using probes and looking/listening for earth based transmissions or electricity distribution noise currents ?.
What is the name of the software I'd like to have a try all the best
You need to be far from AC power lines to have clear reception of VLF as in this video.
I have AC power lines and an AC transformer outside my house and they do not cause any problem when I am listening using a 160 metre band long wire antenna. You can see the AC on 60 Hz on your VLF (0 to 22 KHz) receiver when you listen near 60 Hz but it does not interfere with the stations operating on other VLF frequencies as shown in this video.
can you actualy decode something on theese spectrum (navigation system for instance?)
Not tried yet...

Where does one find this magical software?
Hi Steve, Here is the link: sites.google.com/site/swljo30tb/
Scroll down to the bottom of the page and there is a link named "Files"

@@stevec5000 It was probably designed for windows XP. Nowadays you can use a program like audacity to accomplish the same thing.
whats the name of the software and please provide its link
