    Many thanks, Paul. Had one of your loops for a while now and love it. Loads of contacts QRP with just 5 watts with the Xiegu 5105 just from my shack! Semi disabled so hard to get out into countryside like your wonderful area where you live. 73's Charlie GM1VUT

    I have to say, I have already built a loop like this myself and it actually worked. But my compliments, yours is really very nice and professionally built. However, I admit, I almost only do 5 watt FT8/4 QSOs or CW with my Xiegu 5105. SSB just annoys me. Best wishes, Tom

    You can also use a 4s battery with a load of large diodes in series to lower the voltage, however the diodes do heat up (when tx 100W), once the voltage drops low enough you can pull the diodes out of series. I used large square bolt down type rectifier diodes. You need to check the voltage spec of the radio and it's -+% tolerances to know what is possible or switch to LifePo4 or perhaps LTO cells. If you start to use those lipo cells in parallel you need to be cautious as one cell is always weaker than all the others. For this i would recommend an active balancer, i use the types made with inductors not the type with many capacitors as the inductor type is slightly more efficient. With the active balancer wired into the cells any stronger cells will prop up the weaker ones so that they all drop to 3V around the same time. If you let a weak cell drop below 3V and continue to use it it will die or loose a great deal of it's capacity very quickly.

    Good video Paul, I have been thinking about building a magnet loop antenna for a long time now but just haven’t the time to do the research needed to build the antenna. Very good video and 73 from Deep East Texas KV5P

    Hi Paul,
    Some time ago you did a demonstration of the QRM Noise Canceller/illiminator, and you showed just how good it really was. I'm hearing a great deal of noise on your portable rig, so I'm surprised that you are not using it Paul.
    Would you please be so kind as to explain your reason for not having it, or even a separate one with u when you're out portable please Paul,, ,? ? ?
    Kind Regards,

  • @Oscaro9928

    Great video, one question is being that close the the loop dangerous in terms of radiation?
    Also, is the tuning knob a 6:1 ratio?

    • @OM0ET

      Thanks. Here is explained the danger: www.hamradioandvision.com/small-loop-compliance-distance?fbclid=IwAR1JoS35G38IOROxMlV68i82Qja0IRvZccEHUuDYvVeTg1LreFU8oJPjqHI

    Hello Paul, Keep up the good work,..your magnetic loop is working fine in my x6100. Hope you can make something to increase the power to at least 100watts someday. Keep me update 73/kd6hup.

  • @Oscaro9928

    One more question it looks like when in band you can listen to look for station then tune for transmit. Can you listen to the entire band? If yes, is it true for all bands?
    And what and where is this beautiful little town?

    • @OM0ET
      @OM0ET  2 роки тому

      Yes, if you tune Magloop antenna in the middle of the band you can listen within whole band only with small attenuation on the edges. For transmitting you have to tune antenna every always for the lowest SWR(best efficiency). The name of our village is Nizny Hrusov.

    Hi Paul! How are thinks? I hope well.
    It could be very interesting a comparison between the x5105 and the new x6100 using your magnetic loop antenna and in this form to be able to determine how well transmits and receives each of them.
    Greetings.

      QRP is a way of operating that involves using low power transmitters, that are no more than 5 Watts for Morse or data modes, or 10 Watts pep for voice.

      Hi Phillipe. Horizontal polarization is recommendet only if your antenna has a good elevation, othwrwise the gain will significantly drop.
