So far, the tower mounted equipment is all taken down and I've got a good start on the ham shack. The US Tower crank-up, tilt-over tower will take some effort to move. This is going to be a good deal for someone! More on this later. Here's the first batch of equipment: - Yaesu FT-847 ?satellite? transceiver (with updated, bi-directional serial port) HF-70cm, all-mode - Flex-Radio 1500 transceiver HF-6 meters, all-mode - Diamond SX-1000 Power & SWR meter (both low bands and high bands) - Astron RS-20M power supply - 2-meter rfconcepts amplifier rfc-117 (needs testing) - 70cm Mirage amplifier D3010N (needs testing) - Heil Goldline GM-4 microphone, base and Yaesu cable - Bencher lambic keyer - Dual, Stacked M2 2M12 yagi antennas with PD and phasing lines (one assembled and tuned, one in-the-box) - Dual, Stacked M2 222-5WL yagi antennas with PD and phasing lines (one assembled and tuned, one in-the-box) - Dual, Stacked M2 432-9WL yagi antennas with PD and phasing lines (one assembled and tuned, one in-the-box) - Single, Directive Systems Looper antenna for 1269MHz (AO40 satellite) 2455LYK (new, in the box) - Single, Directive Systems Looper antenna for 2304 MHz 1376LYK (new, in the box) - Single, Directive Systems Looper antenna for 2304 MHz 9112LYK (new, in the box) - Coax and rotor cable! What do you need? This is just the first batch of equipment. There are many other amplifiers, antennas, rotors, etc. etc. that I haven't had a chance to dig into yet (and then the tower). Stay tuned! As you can imagine, I'd rather sell these items locally without the hassle of UPS and PayPal. If there isn't any response I'll go ahead and post these on QRZ, QTH and the Austin for-sale list. The assembled antennas have only been mounted on the tower for 1 ? year and are in excellent shape. Please e-mail direct to jim.k0mhc at earthlink.net for pictures and/or questions you may have. Everything is guaranteed to be complete (all parts) and in working condition (not including antenna kits). Prices are competitive.

Henry Radio Los Angeles Founder Ted Henry, W6UOU, is 100 03/02/2020 Henry Radio Los Angeles founder Ted Henry, W6UOU, turned 100 years old on January 25. The fascinating Henry family history in amateur radio marketing and manufacturing dates back to the late 1920s. The original Henry Radio shop, started by Ted?s brother Bob Henry, W0ARA, opened in 1927 in their hometown of Butler, Missouri, selling equipment and parts for the then-new ham radio hobby. The store stayed in business until Bob Henry died in 1985. Henry Radio Stores advertisements in ham radio magazines were a familiar sight in the post-war years. Ted and another brother, Walt, later W6ZN, worked with Bob Henry during the early years and became fascinated with ham radio. After Ted moved to Los Angeles in 1941, he opened a small radio shop on Westwood Boulevard, which he operated while attending college at UCLA with the intention of going into teaching. His shop survived the suspension of amateur radio during World War II by purchasing gear from hams and reselling it to MARS stations around the world, and by manufacturing crystals (in Butler and Los Angeles) for Hallicrafters? war production. Ted and his wife Meredith, W6WNE, ran the LA store, which grew quickly after the war, expanding to a new location on West Olympic Boulevard, where it operated for nearly 35 years, becoming a gathering spot for hams visiting from around the world. Walt Henry opened a Henry Radio branch in Anaheim, California, in the 1960s, which closed in 1990, after his health declined. In 1962, Ted Henry saw the opportunity to supply tube-type power amplifiers for the ham radio market and began manufacturing the original Henry 2K. The plant was so successful that Henry expanded into the industrial RF equipment sector. In the 1970s, the company developed its own line of solid-state amplifiers, which it still manufactures for various services.?From 1962 until 2005, Henry Radio built approximately 40,000 assorted amplifiers and industrial power generators before closing down the factory in 2005. Henry Radio also became the first Kenwood dealer in the US and marketed the Tempo line of ham gear. The store opened its current facility in 1981 on South Bundy Drive in Los Angeles. Henry Radio is the oldest dealer for the Bird line of RF test equipment, imports Tohtsu coaxial relays from Japan, and manages a trunked radio system, in addition to marketing radio accessories and specialized RF parts and equipment. Ted and Meredith?s son, also Ted, W6YEY, took over day-to-day operation of the business in 1971. The elder Henry retired from the business in 2005. Many of the popular line of HF amplifiers remain in use today./?

International Group to Reactivate the Legendary Yasme VP2VB Call Sign 03/10/2020 On Tuesday, March 10, an international group now in New York will set sail to the British Virgin Islands and activate the VP2VB call sign of /Yasme/ fame for 6 days, focusing on the low bands with two stations. VP2VB was the call sign of the legendary Danny Weil, VP2VB, skipper of the /Yasme/ series of sailing vessels that carried the peripatetic adventurer traveled from one DX location to another in the 1950s and early 1960s. His activities provided the impetus to create *The Yasme Foundation* . For the 2020 ?Yasme Memorial Expedition,? operators will include Adrian Ciuperca, KO8SCA; Martti Laine, OH2BH; Niko Halminen, OH2GEK, and Sandro Nitoi, VE7NY. QSL via OH2BH. A Briton, Weil was, by trade, a watch and clock maker with a sense of adventure. His initial /Yasme/ (often also rendered as YASME) sailing voyage was to the British Virgin Islands. Yasme derives from the Japanese word ?yasume,? which means ?to make tranquil.? Another giant of ham radio history, the legendary DXer Dick Spencely, KV4AA, became aware of Weil?s aspirations and suggested that he combine amateur radio with his ambitious travel itinerary. Spencely taught Weil Morse code and helped him secure the VP2VB call sign, which was to become famous around the globe. Spencely secured the initial ham radio gear for the /Yasme/ and became a tireless fundraiser for The Yasme Foundation as well. Ultimately, there were three /Yasmes/. From 1955 until 1962, Weil operated from several ports of call in the Caribbean and the Pacific. This latter-day VP2VB DXpedition will count toward *Yasme awards* and marks the first activation of VP2VB in more than 60 years. This month?s VP2VB DXpedition will trace Weil?s original route in the British Virgin Islands under a special license authorization, to pay homage to those early years of DXing and to honor the spirit he embraced, which inspired a generation of DXers. Weil?s last expedition in the Pacific included stops at HC8 and FO8 (Clipperton Island), the latter an especially harrowing and life-threatening experience. His new wife, Naomi, was with him at the time. The Mexican Navy rescued them and towed the /Yasme/ to California. Weil went solo to several more stops in the Pacific before retiring from DXpeditioning and settling in Texas in 1963. He resumed his profession of a watch and clock maker there and became a US citizen. He was not to be heard on the air again ? although he kept an ear on the bands. Weil died in 2003 at age 85. The DXpeditions of Weil and of Lloyd and Iris Colvin, W6KG and W6QL, are documented in */YASME, The Danny Weil and Colvin Radio Expeditions/* by Jim Cain, K1TN, commissioned by The Yasme Foundation and published by ARRL. http://www.arrl.org/news/international-group-to-reactivate-the-legendary-yasme-vp2vb-call-sign ______________________________________________________________ South Florida DX Assoc.

Club Log is contributing 120 CPU cores (most running at 3.4GHz) to this project. I have taken the decision to give this work higher priority than Club Log's usual amateur radio functions, so you may see uploads take slightly longer. I do not think most users will notice the additional wait, but I've added a warning to the upload form inside Club Log to explain. I am also looking at dedicating many more computers through my primary business (Third Light). You can read more about this distributed computing project at https://foldingathome.org/2020/03/15/coronavirus-what-were-doing-and-how-you-can-help-in-simple-terms/. You can help, too, by contributing your own computer to the project. If you have a recent home computer with a good graphics card, and if a lot of people make a contribution, it will make a significant difference to the research, potentially reducing decades of work to a far shorter time frame that will make a practical difference this year. Before you rush in, bear in mind that you may incur extra energy costs and produce more heat as your computer will be continually operating at 100% CPU when you are not using it (this is ok on server equipment but make sure you know what you're doing if you are using a normal home computer). To read more, start by opening https://foldingathome.org and follow the instructions to download the client for Windows or Mac if you wish. Club Log has a Folding at Home team, number 246763. Finally, I must let you know that I am stretched quite thinly at work as everything is up in the air. I know others will be experiencing this too. At the moment, I cannot spare much time for the Club Log helpdesk other than at the weekends. Sorry if there is any additional delay replying, but don't worry, Dick W4PID has joined our helpdesk and is already doing a wonderful job taking on your questions. Please also send your support to Marios, 5B4WN, who I am sure will be part of front-line medical efforts to save lives in the coming weeks. To friends of Club Log everywhere, may I take this chance to send you my best wishes. Thanks for making it possible for Club Log to contribute to the Folding at Home project. I also hope you will find amateur radio can fill your days with something familiar and enjoyable! Stay well. 73 Michael G7VJR ______________________________________________________________ South Florida DX Assoc.

INTERESTING STUFF!! 73, DON, W4WJ From: Bill Date: Tuesday, March 24, 2020 Subject: [SFDXA] The Goliath Antenna Network Allowed Nazi Leadership to Communicate with their Covert U-Boat Fleet To: 'SFDXA Reflector' , qcWA From Tony N2MFT: ? The Radio Network that Allowed Communication with Submarines Communicating with covert fleets during WWII required some special equipment. Trevor English By Trevor English March 21, 2020 The Radio Network that Allowed Communication with Submarines FactoryTh/iStock What do you do when you need to communicate with a crew of *50 sailors* submerged in a submarine in an undisclosed location across the world's oceans? That was a difficult question to answer for Navy leaders in WWII. Radio waves don't easily travel through saltwater, which meant that getting active communication with a submarine crew meant making the submarine surface an antenna. This was the obvious solution, but it made a previously covert submarine now a visible target. ? ? The solution to the problem Engineers tasked with finding a more covert solution soon discovered that radio waves with low frequencies, around *10 kHz*, could penetrate saltwater to depths up to around *20 meters*. They realized that if the transponders on submarines were switched to these frequency ranges, then they communicate with leadership on land. The problem with this idea was that creating and broadcasting these low-frequency radio waves required massive antennas. Essentially, the lower the frequency of a radio wave, the longer and larger the antenna is required to be. *RELATED: WHEN THE INTERNET AND CELL PHONE NETWORKS GO DOWN, AMATEUR RADIO NETWORK OPERATORS STEP UP * Engineers honed in on a range of frequencies lower than *30 kHz* for submarine communication. The wavelength of these frequencies were roughly *10 kilometers* or more, meaning that engineers would need massive antennas. The only way to produce these frequencies with such a high range was to use a massive system of antennas with massive amounts of power. Nazi engineers seeking to communicate with their fleet of U-boats designed the Goliath antenna network in Saxony-Anhalt, Germany. After construction, it was operated during World War II and had a transmission power of up to *1,000 kilowatts*. For comparison, that's equivalent to the power draw of *500 average* American households. ? ? The Goliath Radio Transmitter The Goliath network would regularly transmit frequencies between *15 kHz* and *25 kHz*. It was powerful enough to reach any German submarine located anywhere in the world submerged up *20 meters*. The only time communication was hindered was when German U-boats were navigating deep Norwegian fjords. The Goliath antenna used three different umbrella antennas. These were essentially massive antenna towers that were then draped with kilometers of guy wires radiating from the mast. These helped not support the antenna tower, but also formed part of the antenna itself. The Radio Network that Allowed Communication with Submarines /Source:???????? ??????? / In total, the system used three *210 meter* or *688-foot* masts arranged in a triangle. The system also had cables buried around it with a total length of *350 kilometers*. Once it was completed, it had an impressive efficiency of *50%* at *15 kHz* and *90%* at *60 kHz*. *RELATED: YOU COULD DOWNLOAD VIDEO GAMES FROM THE RADIO IN DURING THE 1980S * This massive antenna site was undoubtedly a key strategic tool used by the German Navy in communicating with their U-Boat fleet. After the war ended, the Soviets came in and dismantled the Goliath and shipped it to Russia. It was then erected near Moscow. Today, one of the original towers is still in operation communicating low-frequency signals with submarines and broadcasting time signals. ? ? A deeper dive into how low-frequency networks function Low-frequency radio frequencies are anywhere in the range of *30 to 300 kHz* and their wavelengths range from *1 to 10 kilometers*. Because their wavelengths are so long, they are the perfect tool for long-range communication networks. Low-frequency radio waves, or LF radio, is used for AM radio stations across the world, allowing them to broadcast the same message from a centralized location many hundreds of miles. One of the other massive benefits of LF radio signals is the fact that their long wavelength allows them to diffract over very large physical obstacles, like mountains, or even the earth. LF waves can follow the curvature of the earth with ease utilizing ground wave propagation. Low frequency waves sent through ground propagation can be clearly received over *1,200 miles* from the original source. Another way that LF radio waves can be transmitted ultra-long distances is by intentionally reflecting the waves off of the earth's ionosphere. This is called skip propagation or skywave, and it allows frequencies to be transmitted distances over *190 miles* from the original source. Not as far as ground wave propagation, but still an impressive distance. The other benefit of low-frequency waves, underscored by the Goliath transmitter's use, is the fact that low kHz low-frequency waves, under *50 kHz*, can penetrate ocean depths of roughly *200 meters*. As the wavelength gets longer, the penetration depth gets deeper. Most of the world's superpowers still use some form of this LF transmission to communicate with submarines and underwater vessels today. The Royal Navy nuclear submarines stationed around the United Kingdom listen to a *198 kHz* frequency for orders to launch their ballistic missiles. The U.S. built out something called the Ground Wave Emergency Network, named GWEN. It ran between the ranges of *150* and *175 kHz* up until 1999 when satellites far outperformed the LF network's usefulness. https://interestingengineering.com/the-radio-network-that-allowed-communication-with-submarines ______________________________________________________________ South Florida DX Assoc.
