The world of ham radio is filled with fascinating people, ideas, and projects. One such project that caught my attention is the "continuously loaded, helically wound vertical antenna" designed by Bev AH6NF (YL). In this article, we will analyze the design, materials, and steps to build this antenna, and then we'll give it a try ourselves to see how it performs. Design The design of this antenna is simple yet effective. It is a vertical antenna that is helically wound with a 91cm stinger. The stinger can be folded along the 122cm mast for easy storage. The antenna is continuously loaded, which means that it is designed to operate on multiple bands without the need for an antenna tuner. Materials The materials needed to build this antenna are readily available and affordable. The list includes: 1.22 meters of 1.27 cm white PVC water pipe 9.14 meters of 1.63 mm² insulated electrical house wiring 2.38 mm diameter brass brazing rod, 91 cm long Miscellaneous junkbox stuff Numbe

Building a Dual Band 2m/70cm Yagi Antenna: Tips, Formulas, and Pros and Cons If you’re looking for a reliable and high-performing antenna for your 2m/70cm radio, a Yagi antenna might be just what you need. Yagi antennas are known for their directional properties, which can help you focus your transmission in a particular direction, resulting in better signal strength and clarity. In this post, we’ll take a closer look at how you can build a dual-band 2m/70cm Yagi antenna, including the construction tips, formulas, and potential pros and cons of using this type of antenna. Before we get started, it’s important to note that building a Yagi antenna requires some basic knowledge of antenna theory and construction, as well as some specialized tools and materials. If you’re new to antenna building, we recommend that you consult with an experienced ham radio operator or antenna builder before attempting to build your own. What is a Yagi Antenna? A Yagi antenna is a type of directional antenna

As a ham radio enthusiast, you know that having the right equipment is key to achieving optimal performance from your setup. At TechDarren , we share your passion for ham radio and are dedicated to providing you with the highest-quality equipment available. One of the key things we've learned in antenna construction is the importance of using the right materials. That's why we're excited to offer you a selection of antenna traps made from high-quality materials that are designed to withstand the toughest weather conditions. In addition to our antenna traps , we also offer a range of other Antenna equipment made from the best materials available. For example, we use a 40mm form of Polypropylene tube for its durability and weather resistance. When it comes to connections, we find that mill spec RG58 low loss cable that is crimped and soldered is the way to go. To protect against the elements, we always use UV-resistant heat shrink tubing, and for all fixings, we use A2 stain

The documentary "Ham Radio: The First Social Network" explores the history and appeal of this hobby, and sheds light on how it has evolved over the years. The documentary takes us on a journey through the history of ham radio, starting from the early days of wireless communication to the present day. We learn about the pioneers who made important contributions to the development of this hobby, such as Guglielmo Marconi, who is credited with inventing the first radio telegraph system in 1896. The documentary also explores the cultural and social impact of ham radio. It highlights how ham radio enthusiasts have used this technology to communicate with people from all over the world, forming a global community of like-minded individuals who share a common interest in communication and technology. The documentary also shows how ham radio has played a role in various important events throughout history, such as the Cuban Missile Crisis and the September 11th attacks. One of the mo

This is a project that looks very interesting, it's a dual vfo SSB transceiver published by Pete Juliano, radio ham N6QW and co-host of the popular podcast Solder smoke. so let's get started the first job is to read all the documentation and then read it again. After reading the documentation and printing the documents I emailed Pete and asked if I could get a copy of the Arduino sketch for this project, Pete sent me the sketch as requested. Fantastic thanks, Pete. OK, next job is to get all the parts together,  all parts are all available and as a bonus, we managed to get the mixers ADE-1 supplied by mini circuits in NewYork and mini circuits supplied them free of charge as a sample. sofar so good, ok so let's get a bill of materials together. To do this we used my favourite cad and PCB design tools, Using Easy EDA we started to sketch up the schematics and create a list of part, why redraw the schematics? we hear you ask, we did this so at a later date if everything works

Queen’s Platinum Jubilee Special Event Station As Her Majesty The Queen becomes the first British monarch to reach a Platinum Jubilee, the nation is celebrating this latest milestone in Her Majesty’s record-breaking reign. Ofcom has generously agreed to an RSGB request that radio amateurs licenced by Ofcom use the special RSL 'Q' to commemorate Her Majesty The Queen's Platinum Jubilee. This will be accessible for usage until June 2022, and a Notice of Variation will be required, which will be available at RSGB.org . The Society is also planning other events and activities that it thinks will appeal to a broad audience. More information will be revealed in the coming weeks.  We will be active with special call MQ7ENP from Cotswolds, Worcestershire, England, during June 2022, commemorating the Platinum Jubilee of Queen Elizabeth II. We will be operating on the HF Bands.  

How amateur radio signals are assisting in the search for Malaysia Airlines Flight 370 The work done utilising amateur radio WSPR signals in an attempt to determine the whereabouts of missing flight MH370 has been reported all over the world. The storey has also been covered by 9 News in Australia, in addition to the Times and other national UK media. The assertion by Richard Godfrey that he had found the precise position of Malaysia Airlines Flight 370 at the bottom of the southern Indian Ocean sparked a media frenzy. According to 9 News: Mr Godfrey's research is based on the Global Detection and Tracking of Any Aircraft Anywhere (GDTAAA) software and Weak Signal Analysis. He claims it will lead to the discovery of Mh370.
