    There are Dutch Music Freebanders on 170m, usually between 1620KHz and 1655KHz in AM.

    In Russia (and the former Soviet space) ~1600-1800 kHz is a "pioneer range". Currently used by pirates for negotiations via old-school vacuum tube equipment with hoarse modulation. And, rarely, for unofficial music broadcasting.

    Hi, this band traditionally used pirates because in soviet union pirates often retune typical AM receivers and make simple valve transmitters.
    I recommend for low frequencies two relatively wires 8-20 meters and balun which primary and secondary windings wound on opposite sides of ferrite ring, because this transformer has minimal capacitance between windidngs so he has a high impedance for common mode noises, especially on low frequencies.

    A cheap and still quite efficient loop antenna is the MLA30, offered by numerous vendors on the usual auction site. Just don't use it with a switch-mode power supply.
    A slightly better loop is sold on the usual Chinese site as "50K-500MHz Full Band Loop Active Receiver Antenna". I've had very good results with one of these.
    One strong point of loops is that their directivity features a very sharp null which can be used to attenuate electrical noise from computers, switch-mode power supplies etc. in the close vicinity.
    Another good and extremely compact antenna is the famous Mini-Whip, designed years ago by Dutch radio amateur PA0RDT. Just don't try to use it indoors.

    • @shortwavelistener

      Thanks for the suggestions! I have the MLA-30+ but haven't had a lot of success yet (due to being indoors with it).

THe Box loop you showed I used to have one that was 4ft square 7 turns and 1 pick up turn ... Wish I still had it !and finally if you search Kevin KB9RLW'syou tube channel he has some 'Hulaloops' he built ( mainly for 630m rx) that could easily be moded up in frequency a bit.

    • @shortwavelistener

      I've always wondered about that antenna. Can it really outperform any longer outdoor antenna?

    • @fotoralf
      @fotoralf 3 месяца назад +1

      @@shortwavelistener It can indeed, especially at LF. My MiniWhip is also one of Roeloff's originals but any well-built copy is just as good..
      But one needs to play by the rules: install it outside of the building, as far as possible from your local noise sources, and ground the cable directly below the antenna. A common-mode rejection filter right before entering the building is also a good idea. And don't feed it with a switch-mode power supply. A decent linear power supply is fine, a 12 volt battery is ideal.

    People who really want a high quality loop without breaking the bank should have a look at the head-amp designed by LZ1AQ.
    You'll need to do a bit of tube bending, but it's far cheaper than the Wellbrook and definitely better.

    I'm In Arizona. What azimuth should my wire lay, for a beverage style antenna? like what if I do have room for a 557.743feet (170m) wire, on my land? For London, Hawaii, Costa Rica, Alaska, How do I Aim this thing??

    • @shortwavelistener
      @shortwavelistener  3 месяца назад +1

      @@ranchosinnombreannjimmy8427 Oh wow! You have some land! First thing - AZ is dry and long wires in dry climates tend to build static which can damage a receiver. If you really want to try maybe point the wire NNE towards Europe using a great arc on the globe. Still 170m where you’re located will be difficult. If you point NNW you might get the Half Moon Bay station on 1710 in CA. Beverage antennas are directional parallel to the line of the wire. Definitely do some research on it.

      I've had fantastic results with KAZ antennas for both BCB and 170, 160 Meters. Very directional and somewhat "steerable" with a variable resistor.
      I have a house in Pennsylvania and one in New Mexico and, for me at least, the KAZ antennas have been more versatile and generally perform better than my beverage.
      Good luck 🤞🏻

    Are you all just now waking up ? Those people have been broadcasting for years maybe DECADES !. I tried telling you about the "Russians". Most are on 3000 to 3200 Khz. But as I said years ago,some also frequent 1610 to 1800 Khz. Lots of the transmitters are unstable with simultaneous AM and FM, suggesting home brew transmitters and maybe modulated "Power Oscillators". They are an absolute JOY to listen to !!!
