Excellent video. I made one using a 14 inch diameter embroidery hoop with regular magnet wire. Also one using a loop cut from the top rim of a 5 gal. plastic pail. (about 1-2 inches wide). They work well. More impressive was a 4 turn 6" diameter coil that I hooked up to my 80 meter half wave end fed antenna. My small radio fits inside the coil.

About 5 years ago I built one using a loop of wire, tunning diode, a variable resistor, and a 9-volt battery. The diode seemed to work as well as the variable cap but the tuning diode takes battery power. I think I used a resistor to limit current but I'm not sure now. I predict it won't be long because of DSP radios before variable caps in the electronics junkyards or even part stores are hard to find and I found that a tuning diode and a variable resistor can replace them and I got it to work.

Nice workmanship on your handmade loops. I think I made 4 for either Am Broadcast or 80 meters. Often I include a sense loop and clip it to or jack it to a loop or two I place around the ferrite rod in the radio. The sense and ferrite loop are not needed but why not if you have the time.

Well, much more compact than my wire antenna, but I just put up a random wire and looped it around my AM radio, the grounded the other end. I DXed stations thousands of miles away.

The results are truly amazing. However, it is not clear how the coil turns are located under the screws of the frame to the base. The winding is in a continuous strip. Do the screws pass through the coils of the wire? Short circuit?

Hi Paul, I am in Sydney, Australia. I am looking for your advice. I don't profess to know anything about radios or their reception. I have recently bought a Tivoli One radio to listen to a particular favourite AM station. I am very happy with it. The station I like is comes through quite clear. There is however a buzz like sound coming through. Is there a simple fix for this buzz? Cheers Art

Q U E S T I O N -- Please clarify and confirm: A Q U E S T I O N --- Please clarify! Regarding the loop antennas for AM - ads on Amazon: Our AM radios have electrical cord, adapter, 4-D battery optional connectors. No jack for external antenna. So how and where must we connect the loop antenna to help diminish the crackling on AM 1150? (FM stations = no problem). Are copper wires the best material for AM/FM antennas? Thanks.

Great video Sir! Looking forward for more 🙂 I have the AN-200 Loop and thinking of changing the variable capacitor in order to make it resonate on lower frequencies like 2200m so I can receive some FT8 signals down there. Take Care, looking forward for more videos! 🙂 👍 73! DE1CTL

The AN-200 is tricky to open, you should have ordered the AN-100 for this purphose. The variable capacitor do not need to be replaced, just put another capacitor in parallel; it should work with 300 to 500pF.
