ARRL DX SSB CONTEST! | Winter 2012

Ham radio contest weekend for the ARRL DX SSB contest. Here I am snagging French station F6KHM on 15 meters using 100 watts into my MFJ-1786 magnetic loop mounted just 4 feet off the ground.

This video was taken at the ARRL 2010 Field Day site for the Gulf Coast Amateur Radio Club located in New Port Richey. This was our first attempt at flying a helium balloon with a long wire attached. We used a single conductor 24 gauge wire of 130 feet long. Made successful voice and digital contacts around the country with other clubs. A big thanks to Bill NG4L who recorded and edit this video.

PY1AHD Handheld Magnetic Loop Controller for a HF Light Backpack Magnetic Loop Antenna

You can see on this video my new created device after four years work in designing several remote control systems to tune the variable capacitor of a Small Magnetic Loop Antenna. The antenna can be carried on my back, with a light and simple Back Support described on my web page, or I can temporarily fix the antenna on a balcony or window adjusting the antenna”s resonating frequency from a distant place.

This is both part 1 & 2 of explaining how I constructed my Ham Radio “To Go” box en ligne casino france so KEEP WATCHING AFTER it says THE END. For Portable use both in house and if needed emergency, field day, etc. I plan to use the anderson strip to power my Elecraft KX3 when it arrives to! Will attached KX3 with a bit of velcro or once I get KX3 will see if another way. I have room over my 857 or will change 2 meter mobile to a smaller one(I have a FT-1500 which is smaller)

Testing a coaxial cable HF magnetic loop antenna

Testing a lightweight HF magnetic loop antenna made from 7 metres of RG58 coaxial cable. Contacts were made on 40 and 20 metres during the Lighthouse Weekend. It uses just three main parts: the coax itself, an air-spaced variable capacitor (approx 50 – 100pF max) and a T50-43 ferrite toroid. The toroid is threaded over the coaxial cable. RF from the transceiver is fed via a 2 or 3 turn winding over the toroid (experiment with this for lowest SWR). The coax inner is left unconnected; only the braid is used here. The loop is for low power use only – it will take 10 – 20 watts before the variable capacitor arcs over. Performance is, as expected, somewhere between a smaller pedestrian mobile magnetic loop and a full sized wire antenna. It would be improved if the variable capacitor was a low loss type and the coaxial cable was soldered straight to it. While there’s enough information above to make your own, it’s worth checking out G4FON’s website ( www.g4fon.net ) for similar loops. My loop is closest to his Version 2.
