POTA with a Rybakov - and a lot of intentional QRM

  • How good is the new internet hotshot antenna, the Rybakov? Is it as good as Walt K4OGO and Tim G5TM claims?
    The antenna I am using today is an M0CVO Magitenna, which with it's 7.6m wire and a 4:1 unun is a Rybakov. This was actually the first HF antenna I bought before I got licensed, and I have never really liked it, but since both Tim and Walt speaks highly of the Rybakov I had to give it another try.

      I’ve shown a couple of those QRMers in my latest videos, and there are more coming. If you intentionally make QRM or don’t listen before you key up you deserve to get shown.

    I’ve been dealing with a lot of QRM at my POTA activations. It’s quite disappointing.

      It won’t go away though, so I guess we have to live with it.

    Good stuff, Morten. I've used the Rybakov a few times after learning about it from Walt & Tim. While it worked out well for me (QRP and QRO), what surprised me is that it really seemed to do exceptionally well on 15m and 17m. I've been able to make contacts on 10-12m, but not as easily--that could also be band conditions and timing though. Anyway, I'm glad to see it worked out well for you. It's a nice multi-band antenna option for portable ops. 73

      Absolutely a descent antenna. It might not replace my EFHW, but it’s a great supplement.

    When I activated HA-0006 last week somebody set a carrier on my frequenzy. What he didn't realize: I kicked the automatic notch filter in which of course canceled out the carrier as well as 90% of the band noise :-) So I was able to copy all the week signals from the US which I probably wouldn't have heard otherwise ✌
    A good example of turning something bad into something good 🙂

      Oh absolutely. I should really work on learning how to use filters properly. And it's not that the concept is foreign to me either, I use the same principles on the audio console at work, just AF instead of RF.

    Can you try a Rybakov using an aluminum window screen ground-plane to see if it works better?? 3 foot x 4 foot flat on the ground connected with one alligator clip.

    • @LB0FI
      @LB0FI  Před 9 měsíci

      Window screens are not common here, and if I could fine some it would be too expensive for an experiment. I have no doubt that it would work though, but I can’t see how this would be easier than the radial net I use in this video.
