  • I did a similur thing...Check my channel

    I didnt know the TS2000X could go that low in khz? Did you modify it?

  • No I did not modify it. You turn on the RX RIT control and adjust is down til it shows -20khz. Now you can tune all the way down to 10kHz and the corect frequency is shown on the mail dail (VFO display) display too!

  • What a great idea! I can imagine trying to explain to police what I am doing, when they pull up to see why I am parked by the motorway.

  • Well, that happened to me! I told them I was a radioamateur doing experiments on Longwave radio...They said "OK" and walked away shaking there heads... i guess they were thinking.. "what a nut case!"....At lest they have something to talk about in there coffee break down at the station!

  • Maybe Norwegian police are a little more tolerant than ours. I suspect an amateur would be told to move on over here.

    Again, great idea, nice experiment. Very interesting. I wonder how well that antenna would perform on 73khz for TX? Or even the HF bands? Maybe too lossy for the higher bands, but 160 and 80 might be interesting. It would probably work as an 'end-fire' antenna, with near-vertical radiation from the end, very good in one direction.

  • Well I did try it on 137khz,alos the 160m,80,40, and 20meter band. It was GREAT on 137khz and ok on 160m, 80m was ok (like a 80m dipole), 40m was like a short mobil whip (not to impressive, lacking high angle skywave, but ok on dx) while 20m was very bad! It tuned ok on all bands with the built-in Kenwood TS2000 antennatuner.

  • Good experiment! Thanks for posting! 73's

  • I had no idea that there were signals being broadcast that low.....

    Can you recommend me any websites or search terms for me to be able to find more information on this?

  • Why?

    Because.

    :D

  • If you used a guard rail, what are the chances that the railway line next to my house would make a good VLF antenna, if so would using one line for centre conductor and the other line for ground suffice? The line sections are welded together.

  • You can see the signals, but can you decode them? They don't look like CW, do you know the format?

  • I'd like to see some data, that would be cool.

  • Amazing and fascinating!

  • Once again well done on this video on what you can RX on VLF with a TS-2000.
