    as others have suggested, get a few ferrite toroids ft240-73 and get the antenna wire some 10 turns on it, then 7 or max turns on the AC power cable you connect to yhe radio. those ferrites you have there are doing nothing. finally. before buying anything I suugest you to put the wire straight down on the snow and verify the noise level. I can bet it will improve.

    You have a lovely setup there Matt. I'd love to have a cabin where I could DX from.
    Would it be possible to run (earthed) coax from the house to dipole as far away as possible. Ah just heard you mention this in the video m

      I could run from the house but the noise level is crazy. I will try earthed coax though. I tried an MLA 30+ but the noise was terrible.
      The DX shack will transmit at some point as I’m looking into getting my radio licence as soon as I can.
      Lots more things to do to the antenna though and of course I really need a better ground but that will have to wait until June at the earliest when the snow goes and the ground unfreezes.

    Great! If the antenna is not only in horizontal level, maybe will work better.

    just caught you final comments about trying a 1km wire (oh if only i had the space!!!) just remember you can get some significant voltages induced on a wire that long especially if there is thunder in the vicinity i would not be so keen on hooking a wire that long directly into solid state equipment for that i would definitely be looking at using some form of manual tuner if for no other reason than to isolate the radios from any transient spikes on the wire!

      I'm a bit of a vagrant. Little pension and my auto and a park for a work space so it's off to the auto parts shop. In the sted of a tuner I use math to cut 1/4 wave wire for bands of interest, and store them in old suit case. Then select. The one I need, hang it use it. Works well . I'm 73 year old. And worked for army and 30 years in tv factory. Now near home less. Radio is my hobby all ways be my hobby. Stick with it om. Sgt Williams will follow your exploits.

    Matt get a amateur radio handbook such as the ARRL or British ones and they have suggestions for various low noise antennas or directional ones such as the beverage Antenna which is generally low height long wire with a 50 ohm ground in the direction of where you are trying to DX. You already have the wire, and a 50 ohm does not have to be high wattage unless you plan to transmit on it.
    73!

      Will get the book, thanks for the suggestion.
      Today I’m going to improve my grounding I have a copper pipe that I will drive into the ground. I’m using the Kenwood’s 200 ohm antenna connections.
      During the summer the beverage antenna will be setup properly but as the snow is waist deep it’s tough going!

    As the antenna enters the room it picks up all the noise around the cottage. I also think you can improve reception by terminating the antenna at a distance from the cottage (10 -20m) in a 9:1 unun. At that place you should also have your ground, so I would chose the most humid place around the cottage. And from there, run a 50 ohm coax inside to the receiver.

    My experience is that height of antenna is most crucial. You have very friendly trees around to support wire at higher level. But is needed to build any "catapult" to fire any wire so that it could jump above high arm and end to fall down to fix it. In my place I have lot of noise but still it is 10x better and I can catch also DX signals in compare to what I can receive at sea level 60 meters below. Beacuse there is literaly only noise.

    • @MattinLapland

      This wire is just a temporary solution as the snow is up to my waist so getting around is hard. The height is a lot higher when you don’t count the snow.
      I need to get various things like a terminating resistor, ATU and UnUn…..so much more to do!
      The results are already really good especially on Shortwave it has opened up stations that I could never hear before even on a 30m wire.

    In my experience many if not all Chinese inverters radiate even if they have an 'EC' mark. Find an EU manufactured inverter.

    Ah a cheep rig when I go out is the xh data d 219 . With a ridiculous sum of 2.5 meter wire an it's thrown out of the auto. The radio locks on and doesn't wonder away. 😊😊😊 PS l had a ac radio That had a pair of x former in line with in coming ac this tended to cut hum.

    Be aware, significant voltage can be induced into long aerials, and are prone to lightning strikes. This will damage the R2000. This radio was a victim of the bean counters, and has only rudimentary front end protection to minimise manufacturing cost. There is little point in going beyond a full wavelength of the frequencies of interest. The R2000 also has an overloading issue caused by limited dynamic range, so large input signals can actually harm reception rather than improve.

    • @MattinLapland
      @MattinLapland  3 หลายเดือนก่อน +1

      At the moment it’s just connected to the 500 ohm input with a good ground but in the future there will be a bit more protection. The 100m wire is working so well so I’m not going to change this for a while.
      The antenna is never left connected and grounded before use.

    get a run of decent coax from the radios to the outside a good few meters from the buildings and experiment with a 1:1 choke unun and perhaps one with another ratio that may suit your wire better like a 9:1 or a 48:1 that should kill off most of your local noise.
