    Wow, listening down there at the bottom end is a completely different business. I honestly have never thought to use an audio interface as a receiver, that's a whole different lane of lateral thinking. Well done and thanks for sharing! A merry Christmas! 73, Jan M7HNK

      @fotografm Hello Jan. Thank you for your interesting comment. The sound card is a simple idea which I got from a youtue video about listening to the Schumann resonance around 6 or7Hz ! Even the soundcard built in to most PC's can function quite well, often with higher noise floor though. Merry Christmas to you too !

    Good day Simon, I had high hopes this morning, being all ready to go with my Sailor R-1120 receiver, coupled to my Wellbrook 1530+ antenna....
    I heard nothing on 17.2 kHz unfortunately.
    Quickly changed over to my SDRplay-RSPdx. And strangely enough, I did see and hear a faint signal on 18 kHz, same as visible on your recording in your video. But not anything on 17.2. Gggrrrr ;-)
    So, this is something to study more, to make this work.
    In the past, I do remember I was successful with my Skanti R-5001, which is currently " on the side" . It's a heavy, big beat...
    Interesting though, using either a soundcard or the mentioned mic- pre amp.
    So much to explore still. To be continued.

      Hello Roy. Thank you for your interesting comment. It was interesting to see those receivers on your QRZ page as they are unknown to me. The sound card is a simple idea. Even the one built in to most PC's can function quite well, often with higher noise floor though. Good luck with your experiements !

    I missed the transmission. I was hoping to catch it with a Wellbrook loop and an RSP-dx from the Midlands of the UK but totally slipped my mind to set my alarm - It is Christmas and I am on holiday :) I am hoping to visit Grimeton at some stage with a friend and colleague at some stage. Reading other comments I may need to rethink the receive setup for VLF - I need to have a look at the Airspy HF+....
    The Behringer performed incredibly well! If you are looking at antennae, have a look at the Wellgood loop antenna - I bought one as a backup for if/when my Wellbrook dies as the company and founder are sadly no more. It is based on the Wellbrook loop amplifier but I've not had a reason to try it in anger yet. The Wellbrook pretty much prevented me throwing to towel in due to HF noise - it is a godsend.
    I moved from Windows over 15 years ago to Ubuntu firstly and then Mint about 10 years ago. All of my systems run Linux and I have a Mac for Office applications. Life is sweeter and easier without the aggravation of Windows. When my partner had her last laptop she asked me to put Mint on it and has been running it since (7 years or so?) and I don't get hassled with support issues - it just works.
    I do run Windows in a VM (best place for it) on my main shack/office machine to run SDR Console and a few other apps but everything else radio related is native Linux.
    Just found your channel and subscribed.

      Thank you for your interesting comments, Richard. I also have a Wellbrook loop which is great except that it takes up more space and doesn't work quite so well at 17kHz as the PA0RDT MiniWhip. There is an "improved" design called the Wellgood Loop and I thought that if ever my Wellbrook preamp broke then I would replace it with a Wellgood version. Yes - the loop antennas certainly have better noise immunity than electric field antennas. I tried installing SDR-Console under Wine on Ubuntu without much success. Maybe I will try it again using Bottles. I use a standalone Proxmox server as my VM host which works extemely well, except that the RTLSDR USB connection does not pass through fully to a VM, otherwise I would be running windows as you do. SDRPlay technical support was unable to help with the problem. Which VM hypervisor do you use which allows access to the RSPDX ? I am also trying out SDRConnect from SDRPlay which is getting better and runs nicely with the RSPDX on Linux.

      @@fotografm Hi Simon, I'm using Oracle VM Virtualbox and seems to work pretty well. I did think about using WIne initially but there seemed to be many caveats and I thought I would get better compatibility going down the VM route. All of the USB devices that I want to pass through (RSPdx, Elad TM2 and the IC-9700 work well and are seen by SDR Console and SDRUno. I would like to move my OS to a newer version of Mint to run SDRConnect but as the machine is stable I'm loathed to make large changes to it. I have a replacement SSD drive to do it but it's like going to the dentist - only go when necessary :)

      @@rjy8960 Hi Richard. I will give Oracle VM Virtualbox a try. I ran it on windows a while back and remember discovering I needed to install the correct extension pack to make things work so will try it on Mint. I know what you mean about upgrading - "If it ain't broke, don't fix it" ;-) Are you running windows 10 or 11 in your virtual machine ?

      @@fotografm Windows 10 - I'm going to stay with 10 for as long as I can although you can access the TPM with Oracle VM AFAIK although I don't want any more advertising, telemetry and scumware that is / may be included in 11. I only use a Windows VM on this machine because I need base OS support and not because I want it. If I have to move then I will but at the moment absolutely no plans to upgrade.
      I've limited the resources available to the VM to what it needs to run the programmes I need and no more as I see it only as a necessity rather than a choice :)
