Memorial Day QSO
by WARREN MYERS 08 Nov '26

08 Nov '26

Propogation was good to Europe this evening. One of many stations operating was this one. Apros pos for our Memorial Day. 73s de KN6ZZI Warren > > https://www.qrz.com/db/TM80BON > > TM80BON - Callsign Lookup by QRZ Ham Radio > > TM80BON > > Celebrating the 80th anniversary of the Battle Of Normandy > > The Battle of Normandy > > The Battle of Normandy was one of the major confrontations of the Second World War. In terms of the number of German soldiers it mobilized, and the losses it inflicted on the Wehrmacht, which emerged from fierce fighting that sometimes ended in hand-to-hand combat, this battle played a fundamental role in the liberation of France and Western Europe. From the assault on the landing beaches to the German retreat into “death row” in mid-August and the liberation of Lisieux on August 23, 1944, the Battle of Normandy lasted some 80 days. From the hell of the hedgerows to the outskirts of Caen, it was almost three months of bitter, often indecisive, always violent fighting. For soldiers and civilians alike. A total of 20,000 Normans were killed (14,000 in Lower Normandy alone), most of them victims of Allied aerial bombardment, with some towns completely devastated by a veritable carpet of bombs. The Allies lost just over 200,000 men, including 37,000 killed. For the Germans, the human toll was difficult to establish, ranging from 300,000 to 450,000 casualties, including 55,000 to 60,000 killed. The Wehrmacht lost no less than half of the troops it had committed to Normandy. > > The strategy imposed by Hitler himself was to hold out at all costs to contain the Allied invasion, while awaiting the hypothetical arrival of secret weapons that were supposed to change the course of the war. The ensuing war of attrition tipped the balance in favor of the Allies, who, thanks to a formidable logistical effort, managed to bring more munitions, more weapons, more oil and more men to Normandy. > > By the evening of June 6, the 156,000 Allied troops on the ground in Normandy were facing 80,000 German soldiers. From then on, it was of the utmost importance to consolidate the bridgehead and the numerical advantage by hindering the arrival of German reinforcements as much as possible. For this reason, a dozen towns in the Lower Normandy region, all of them road junctions, were razed to the ground by Allied bombing raids, from Pont l'Evêque to Coutances, via Vire, Condé-sur-Noireau, Lisieux and Saint-Lô, the “capital of ruins”. Railway infrastructures and bridges were also particularly targeted. Under these conditions, German reinforcements were hard to come by. Most of them came from Brittany, southwest France and even Scandinavia. If German troops did not flock en masse to the Normandy front, it was also due to the success of the intoxication operation carried out by the German High Command, which remained convinced until mid-July that the Normandy landings were merely a diversion before the real landings, which would take place in the Pas-de-Calais. The Germans thus deprived themselves of von Salmuth's XVth Army, whose arrival in Normandy in the days immediately following the landings would undoubtedly have further complicated the Allies' task. > > Two weeks after D-Day, some 640,000 of them were on the Normandy front, compared with 250,000 Germans. By August 1, 1,600,000 American, British and Canadian soldiers were engaged in Normandy, compared with 510,000 Germans, i.e. three times as many. The German army found it extremely difficult to replace its losses, and the imbalance became more pronounced as time went on. In the East, the launch of Operation Bagration by the Red Army on June 22, 1944, kept almost two-thirds of the Wehrmacht's forces on the Eastern Front. And yet, apart from a few quick successes, such as the capture on June 26 of Cherbourg and its deep-water port, vital for ensuring supplies, the Allies had the greatest difficulty in advancing, falling well behind the timetable set by the high command. For example, Caen, which was to have been taken on D+1, was not fully liberated until July 19, after six weeks of fierce fighting and heavy losses on both sides. And if the British and Canadians had long been stymied by the Panzerdivisionen's armored lock on Caen, what could be said of the Americans trapped in the “hedgerow hell” of the Bocage? > > Firmly entrenched in their positions, German soldiers held out against the Allies, forcing them into a war of attrition.The inferiority of their numbers is partly offset by the fact that the ratio of combat troops to logisticians is much higher than it is in the Allied ranks, where the latter account for around half the men.Above all, the German fighters were far more battle-hardened than their opponents, and some of them belonged to elite units that had earned their spurs on other battlefields, such as a number of SS armored divisions.Conversely, many Anglo-American soldiers landed in Normandy for their baptism of fire: this was the case for 70% of them.Finally, the terrain was largely unfavorable to the attackers.The Normandy bocage, with its fields enclosed by dense, impenetrable hedgerows, provided the Germans with formidable defensive positions from which they took full advantage, inflicting heavy losses on the Allies throughout July 1944. > > A major advantage for the Allies: total control of the skies.For their airmen, the danger came not from Luftwaffe aircraft, but from the guns of the FLAK (anti-aircraft artillery), in particular its 88mm guns, also used as formidable anti-tank weapons, effective up to an altitude of 8,000 meters. On land, Germany's undeniable material inferiority in quantitative terms is partially offset by its qualitative superiority.Such is the case with the formidable German MG42 machine gun, whose rate of fire of 1,500 rounds per minute is three times greater than that of American - Browning - and British - Bren - machine guns.During the Battle of Normandy, the Allies engaged a total of 8,700 tanks and tank destroyers, compared with 2,300 tanks, assault guns and tank destroyers on the German side.But the quality of the German Tiger and Panther tanks outshone that of the Churchill, Cromwell and Sherman tanks. Armored divisions were the Wehrmacht's strong point in Normandy. On the other hand, the Allies' artillery was insufficiently motorized, leading to massive use of horse-drawn carriages.Between 2,600 and 3,600 Allied tanks were destroyed in Normandy, compared with 1,000 to 1,500 on the German side. But the Allied replacement tanks arrived so quickly that their numbers eventually outnumbered their losses, which was far from being the case for the German army, which directed most of its production to the Eastern Front. Although some 2,000 kilometers away, the Eastern Front played a decisive role in the outcome of the Battle of Normandy. > > Code-named Overlord > > The great Allied offensive was launched on June 6, 1944 to create a new front and liberate Europe.Its primary objective: the landing of troops and equipment on the Normandy coast at dawn on June 6. The very next day, the Battle of Normandy began, with the aim of regaining control of ports, airfields and supply depots.On June 7, British troops landed on Gold Beach (Arromanches), liberating Bayeux. The town suffered no damage and became a rear base in the liberated territory, essential for supplying the armies and receiving the wounded. > > THE ADVANCE OF ALLIED TROOPS ON JUNE 7 > > The day after the D-Day landings on June 6, 1944, Allied troops began advancing inland from Normandy. Some Normandy towns, such as Bayeux, were quickly liberated, while others proved more difficult to recapture, at the cost of many casualties. > > On June 7, 1944, British units entered Bayeux without a fight and liberated the town. The same could not be said of the Caen sector, where the attackers came up against a fierce defense. Two attempts to bypass the city of Caen, which controls the routes to the Seine and Paris, were unsuccessful. > > For their part, the American troops set their sights on taking Cherbourg, in order to gain access to a deep-water port. On June 17, 1944, the Americans reached Barneville-Carteret. As a result, the Germans retreated to the north of the Cotentin peninsula. Cherbourg was not taken until June 26, 1944, but the port was completely destroyed. > > OPERATION COBRA, A DECISIVE TURNING POINT > > At the other end of the front in the Cotentin region, the Americans captured Saint-Lô on July 18, 1944, after a difficult and deadly hedge war south of Carentan. A week later, thanks to the arrival of reinforcements and improved weather conditions, the Americans were able to intervene on a massive scale. > > General Patton launched Operation Cobra on July 25, 1944, breaking through enemy lines. On August 6, 1944, the Germans launched a counter-attack in the Mortain region towards Avranches to cut off the American advance. But a carpet of Allied bombs led to the failure of this enemy operation. Soon encircled in the Falaise pocket, the German armies withdrew towards Paris. The Battle of Normandy ended at the end of August 1944. From then on, the Allies advanced rapidly eastwards, through Brittany and into the Pays de Loire region... > > LE GÉNIE MILITAIRE OU LA LOGISTIQUE DE LA VICTOIRE > > During the operations of the Battle of Normandy, military engineering units played a vital role in the victory. The museum pays tribute to them. An emblematic Caterpillar D7 bulldozer is on display in one of the rooms of the Musée Mémorial de la Bataille de Normandie. This type of machine played an essential role in clearing the ruins of bombed-out towns, and was used by British engineers to build the Bayeux By-Pass. > > 2024 > > In 2024, Normandy will honor the memory of these events and the men and women who came from all over the world to liberate us.A regional mobilization will take place to celebrate this tenth major anniversary.This will be an ideal opportunity for visitors to discover or rediscover the main sites of remembrance, cemeteries, key places and museums that bear witness to this tragic era.Today, these important places are imbued with fundamental and universal values such as Reconciliation, Peace and Freedom. We hope your visit will be a privileged moment to share with your loved ones. > > Link to all informations regarding the Battle of Normandy > > https://en.normandie-tourisme.fr/discover/history/d-day-and-the-battle-of-n…

As in previous years, I am acting as the volunteer coordinator, and Mike Felio will be the comm lead during the show Each day is divided into two shifts, a morning shift and an afternoon shift There are two main types of jobs, the roaming color teams (and rovers), and the net control (and comm lead / asst comm lead) jobs Plus a show director "shadow" job, which should be a very exciting close-up assignment, you will have two radios: a commercial show radio and your ham radio. The Shadow will follow the show director and provide communication support to the show director. You are welcome to sign up for two consecutive Shadow shifts and stay with the show director for the entire day. The net control (and comm/asst comm lead) will be based in the comm trailer, slightly longer shifts to ensure overlap between morning and afternoon shifts The showgrounds is divided into four sectors A/B/C/D (maps showing the four sector and grids will be provided) There are four two-person color teams (blue/green/purple/red), each two-person color team will cover one of the show sectors for an hour and then move to a different sector (as instructed by net control), allowing each color team to enjoy all sectors of the show. The rover position is similar to color teams, but roves solo and not limited to single sector at a time and can rove over the entire show, also acting as a "gofer" and as backup for any color team member who might need to take a break The color teams and rovers will stroll through the showgrounds enjoy the static displays and the airshow above, while providing eyes/ears/comms Plan on four hours of walking in the hot August sun.

Sorry for never replying. I helped another ham get his Bridgecom setup configured and working over the weekend, which got me inspired to get my DMR going again. I had already changed my DMR ID from a 1xxxxx number to a 3xxxxxx number in Feb, but hadn't updated my OpenSpot or radios. Tried but then found out that Brandmeister purged my acct! I had to re-register, and confirm my license with RadioID. Right now Brandmeister is happy, my OpenSpot 1 is happy, just need to update my radios now.

New Video: Vintage Radio Navigation Systems Still in Use Today
by Levi C. Maaia 21 Mar '25

21 Mar '25

Dear SBARC members, I wanted to share a new video I’ve just released that may be of interest to many of you, especially those curious about the intersection of radio and aviation technology. 📺 Watch the video here: https://youtu.be/BwHVqb2MRoM?si=VbctiwQvgfZLmwkg In this episode of Digital Voyage, we take a Cessna 182 up over Santa Barbara to explore how some of the earliest radio-based navigation systems—like VOR beacons—are still in use today. These systems, developed more than 80 years ago, continue to guide aircraft alongside modern GPS-based avionics. We also take a look at how pilots receive real-time traffic and weather information using ADS-B, a system that will be familiar to those of you with SDR or flight tracking setups at home. Topics covered include: – How VHF radio beacons still provide reliable navigation – The role of ADS-B in traffic awareness and public flight tracking – Integrating modern GPS with legacy autopilot systems – The shift from paper charts to tablets – What pilots do when GPS fails or is jammed If you’re interested in radio navigation systems, aviation, or just enjoy seeing vintage and modern tech work together, I hope you’ll take a look. Feel free to share with other hams and fellow tech enthusiasts. Always happy to talk more about the RF side of aviation. LCM Levi C. Maaia, K6LCM www.levimaaia.com

We have been careful not to overly stir up dust as the mentioned sites are the worse. Anyone with pulmonary issues should remain clear of the worst offending sites. > Bill Talanian >> From Wiki > Orthohantavirus is a genus of viruses that includes all hantaviruses (family Hantaviridae) that cause disease in humans. Orthohantaviruses, hereafter referred to as hantaviruses, are naturally found primarily in rodents. In general, each hantavirus is carried by one rodent species and each rodent that carries a hantavirus carries one hantavirus species. Hantaviruses in their natural reservoirs usually cause an asymptomatic, persistent infection. In humans, however, hantaviruses cause two diseases: hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS). HFRS is mainly caused by hantaviruses in Africa, Asia, and Europe, called Old World hantaviruses, and HPS is usually caused by hantaviruses in the Americas, called New World hantaviruses. > > Hantaviruses are transmitted mainly through aerosols and droplets that contain rodent excretions, as well as through contaminated food, bites, and scratches. Environmental factors such as rainfall, temperature, and humidity influence transmission. Human-to-human transmission does not occur. HFRS is marked by kidney disease with kidney swelling, excess protein in urine, and blood in urine. The case fatality rate of HFRS varies from less than 1% to 15% depending on the virus. A mild form of HFRS often called nephropathia epidemica is often caused by Puumala virus and Dobrava-Belgrade virus. For HPS, initial symptoms are flu-like, with fever, headache, and muscle pain, followed by sudden respiratory failure. HPS has a much higher case fatality rate than HFRS, at 30–60%. For both HFRS and HPS, illness is the result of increased vascular permeability, decreased platelet count, and overreaction of the immune system. > > Individual hantavirus particles (virions) are usually spherical and vary at 70–350 nanometers in diameter. They consist of the viral RNA, which is segmented into three parts and encased in helical nucleocapsids to form three ribonucleoprotein (RNP) complexes. Attached to each RNP is a viral RNA-dependent RNA polymerase (RdRp). RNPs are surrounded by a lipid envelope that has spike proteins emanating from its surface. Each part of the viral genome is single-stranded negative-sense RNA. The segments encode one protein each: RdRp, which performs transcription and replication of the genome, a glycoprotein precursor, which is formed into surface spikes on the envelope, and the N protein, which binds to and protects viral RNA. Some hantaviruses encode on the same segment as the N protein a non-structural protein that inhibits host interferon production. > > Hantavirus replication begins by attaching to the surface of cells, usually vascular endothelial cells and macrophages. They then enter the cell and form vesicles to be transferred to endosomes and lysosomes. The viral envelope fuses with the membranes of endosomes and lysosomes, which empties the viral RNPs into the host cell's cytoplasm. RdRp then transcribes the viral genome to produce messenger RNA (mRNA) for translation by host ribosomes to produce viral proteins. RdRp also produces copies of the viral genome for progeny viruses. Old World hantavirus virions are constructed in the Golgi apparatus and obtain their envelope from the Golgi apparatus, before being transported to the cell membrane to leave the cell via exocytosis. New World hantavirus virions are constructed near the cell membrane, obtain their envelope from the cell membrane, and leave the cell by budding from its surface. > > Hantaviruses were first discovered following the Korean War. During the war, HFRS was a common ailment in soldiers stationed near the Hantan river. In 1978 in South Korea, the first hantavirus was isolated, Hantaan virus, and was shown to be responsible for the outbreak during the war. Within a few years, other hantaviruses that cause HFRS were discovered throughout Eurasia. In 1982, the World Health Organization gave HFRS its name, and in 1987, hantaviruses were classified for the first time, and they collectively bear the name of Hantaan virus and the Hantan river. In 1993, an outbreak of HPS occurred in the Four Corners region in the United States, which led to the discovery of pathogenic New World hantaviruses and the second disease caused by hantaviruses. Since then, hantaviruses have been found not just in rodents but also shrews and bats. > > > -------------- next part -------------- > A message part incompatible with plain text digests has been removed ... > Name: not available > Type: text/html > Size: 18933 bytes > Desc: not available > > ------------------------------ > > Subject: Digest Footer > > _______________________________________________ > SBARC-list mailing list -- sbarc-list(a)lists.netlojix.com > To unsubscribe send an email to sbarc-list-leave(a)lists.netlojix.com > > > ------------------------------ > > End of SBARC-list Digest, Vol 156, Issue 2 > ******************************************

Hantavirus is also susceptible to bleach disinfection. 1/3 cup of sodium hypochlorite per gallon of water upto 1 1/2 cup per gallon depending on how dirty the surfaces are.Can put in a spray rig. Wait 1/2 hr. and then rinse or wipe surfaces clean. If necessary (depending on surface) can neutralize with baking soda if needed to preserve the surface.Roy DuggerMobile -------- Original message --------From: WARREN MYERS via SBARC-list <sbarc-list(a)lists.netlojix.com> Date: 3/14/25 07:15 (GMT-08:00) To: sbarc-list(a)lists.netlojix.com Cc: WILLIAM TALANIAN <w1uuq(a)cox.net>, Michael Ditmore via SBARC-list <sbarc-list(a)lists.netlojix.com>, WARREN MYERS <wwmyers(a)me.com> Subject: [Sbarc-list] Re: SBARC-list Digest, Vol 156, Issue 2 Theo and SBARC technical colleagues,Below are a couple of resources that may be useful in understanding Hantavurus, how it can be transmitted to humans and how to mitigate the risk of infection. Of note, Hantavirus is transmitted via inhalation of aerosolized excretia. My reading of this leads me to recommend, in addition to proper handwashing after a potential exposure, wearing an N-95 rated mask and gloves while in a facility known to be contaminated with rodent feces/urine, would be prudent. The text below the web links is the result of an AI inquiry on the question. WarrenAbout Hantaviruscdc.govHantavirus Preventioncdc.govFrom Microsoft’s CoPilot A.I.To protect themselves, individuals working in rodent-infested spaces should take the following precautions. - **Wear protective gear**: Use gloves, masks (preferably N95 respirators), and goggles to minimize exposure.- **Ventilate the area**: Before cleaning, open windows and doors to allow fresh air to circulate for at least 30 minutes.- **Avoid stirring up dust**: Do not sweep or vacuum rodent droppings, urine, or nesting materials. Instead, spray the area with a disinfectant or a bleach solution (1 part bleach to 10 parts water) and let it soak before wiping.- **Practice good hygiene**: Wash hands thoroughly with soap and water after handling potentially contaminated materialsOn Mar 13, 2025, at 11:35 PM, WILLIAM TALANIAN via SBARC-list <sbarc-list(a)lists.netlojix.com> wrote: TheoLike yourself our techs are really at dirty sites and I never can understand how site managers and government itself don't tackle the issue.

The rodents ate all the wiring jackets under the chassis. There is often lots of evidence of rodent urine and droppings inside the racks and enclosures.

by WARREN MYERS 03 Mar '25

03 Mar '25

Hello Friends, I will be traveling to Cape Verde in May for a Holiday Style DXpedition. I will be partnering with Harald - D44TWO, an experienced DXpeditioner. My call sign for the activity is D44ZZI. And, we hope to be active on most if not all HAM bands and modes. My objective is to practice and learn how to conduct a DXpedition, and of course to enjoy the West African archipelago of Cape Verde. Hope to see you on the air. Warren KN6ZZI D44ZZI
