Many thanks to SWLing Post contributor, Pavel Kraus, for the following guest post: Building a Drain Pipe FSL Antenna by Pavel Kraus Hi, I greet all DX fans and the entire SWLing Post community! I enjoy reading reading this blog and the diversity of contributions from our authors and contributors; many thanks from me for […]
Many thanks to SWLing Post contributor and Ultralight DX enthusiast, Gary DeBock, for sharing the following guest post: Nulling a local pest with dual FSL Loops by Gary DeBock After many dual FSL antenna experiments I’ve finally determined how to effectively cancel out QRM from a local pest that is off to the side (ideally […]
Many thanks to SWLing Post contributor, Gary DeBock, who shares a video of his latest Ferrite Sleeve Loop (FSL) antenna: the 3″ Baby FSL. Gary Notes: The new design 3 Inch (76mm) Baby FSL antenna is the smallest, most compact and lightweight of the “airport friendly” FSL’s developed here recently, but it provides a very […]
Many thanks to SWLing Post contributor, Gary DeBock, who shares the following: Daytime DX Shootout– a new-design 4.7 inch FSL antenna ($62 construction cost) goes up against the Terk Advantage AM commercial loop ($58 on eBay) in the daytime DX reception of 650-CISL (10 kW at 160 miles, in Vancouver, B.C.). The first 20 seconds […]
Many thanks to SWling Post contributor, Gary DeBock, who shares the following note about his latest FSL antenna experiment: Medium wave DX FSL antenna phasing experiment– 1593-CNR1 (Changzhou, China, in Mandarin) boosted up to strong (S9) peaks by two 5 inch “Frequent Flyer” FSL’s at 1435 UTC on February 25th in my frozen back yard […]
Introduction I’m very fortunate to live across town from my good radio hobby pal Gary DeBock. He has been responsible for the rapid growth in Ultralight radio DXing and the construction of Ferrite Sleeve Loop (FSL) antennas. Living near each other as we do, I’ve benefited a lot from his expertise and creativity in the […]
