Dan looks at techniques for everything from through hole resistors to the miniscule SMD components used in modern electronics using both a soldering iron and hot air. There is also a discussion on soldering equipment, what to look for when purchasing modern component packages, PCB cleaning, and reflow soldering as used in professional environments. As silicon processing technology improves and PCBs are required to become increasingly dense, amateur constructors\u2014or homebrewers\u2014are required to undertake soldering of smaller and smaller components to keep up with progress within industry. While many excellent designs have been created using large DIP or SOIC size parts such as the venerable SA602 and 741 op-amp, if we restrict ourselves to such devices, the gap between this and what is possible with modern devices will only continue to increase.<\/p>\n<\/li>\n<li><strong><a href=\"https:\/\/youtu.be\/BjnMiqlJRdM\" target=\"_blank\" rel=\"noopener noreferrer\"><em>Portable operating for the terrified or inspired<\/em><\/a><\/strong>\n<p style=\"font-size: 12px;\">Michael Sansom, G0POT<br \/>\nThis presentation should help you try out portable operating, or improve your results. Many of us are finding that operating from home is challenging. Levels of urban radio frequency interference (RFI) seem to be on the up, and many of us have limited space or live in apartments or rented accommodation making aerial erection difficult. One option is to take your station out into the countryside; but how effective is this and how much effort do you have to put into building a portable station, and is it effective? In this talk, Michael looks at different options for getting started or improving your portable operating; the challenges, and some of the fantastic benefits.<\/p>\n<\/li>\n<\/ul>\n<ul>\n<li><strong><a href=\"https:\/\/youtu.be\/pHQsftZhogY\" target=\"_blank\" rel=\"noopener noreferrer\"><em>Having fun with electronics, coding and amateur radio<\/em><\/a><\/strong>\n<p style=\"font-size: 12px;\">John Hislop, G7OHO and the STEAMettes<br \/>\nFour years ago, John, G7OHO started a STEM club for a group of boys and girls in Key Stage 2 of a primary school, aged seven and older. He introduced electronics, coding and activities associated with amateur radio, with the aim of having fun. If they learned facts along the way, such as how transistors work, that was a bonus. Now the club has incorporated art to become a STEAM club and has girls only. Because the girls have learned Morse code they call themselves the Morse Ninja STEAMettes! They have achieved a lot in those four years. The girls have enjoyed downloading telemetry and \u2018fitter\u2019 messages addressed to them from the FUNcube-1 educational satellite. They are now using the satellite to send a CQ to operators around the world. Other activities include sending a greetings message to the astronauts on the ISS, making the Snail Morse key, learning Morse code with the Long Island CW Club, amateur radio direction finding, and lots more! The girls\u2019 investigations of the BBC micro:bit V2 and how it can be used to send Morse code by radio led to a three page article in <em>RadCom<\/em> magazine. They also gave a video presentation to the <em>QSO Today<\/em> online conference. Now John feels that they are ready to get their amateur radio licence. It\u2019s time to drop the club call sign and get their own! This presentation highlights some of those activities that would be of interest to STEM club leaders and radio clubs who would like to attract youngsters into the hobby.<\/p>\n<\/li>\n<li><strong><a href=\"https:\/\/youtu.be\/F1EJfKUcbMo\" target=\"_blank\" rel=\"noopener noreferrer\"><em>Solar cycle 25: the good, the bad and the downright ugly<\/em><\/a><\/strong>\n<p style=\"font-size: 12px;\">Steve Nichols G0KYA<br \/>\nSteve, G0KYA, chairman of the RSGB\u2019s Propagation Studies Committee, looks at what we can expect from the upcoming solar maximum in this talk.

It covers the evolution from DSP and discusses the merits of hybrid SDR technology. He goes on to cover SDRs with multiple receivers, the limits of direct sampling, FFT and the panadapter, and multiple receivers; finally taking a look at DFC\u2014direct Fourier conversion\u2014and some advancements for SDR transmitters. The talk is technical, but not too technical. No maths\u2014well not much\u2014no software code, and no vector diagrams. It is suitable for those who want to learn more about software-defined radio, whether you already own one or not.

During the Second World War, German intelligence agents were deployed to mainland Britain to spy on British military activity. Monitoring and reporting of their wireless transmissions fell to a small, secretive and largely unknown unit manned almost exclusively by volunteers. The Voluntary Interceptors (VI) as they became known would spend hours every day at home monitoring their receivers for often faint and difficult to copy signals transmitted by these German secret intelligence services. This unit was to become known as the Radio Security Service (RSS) and was part of the core of the signals intelligence production effort at Bletchley and the insights into German military tactical and strategic planning. It was a vital part of the successful Double Cross programme mounted by British intelligence to deceive the Germans. This talk focuses on the secret world of the Radio Security Service\u2014its existence was only made public 35 years after the war ended, shortly after Bletchley Park\u2019s secrets were exposed. Patrick Reilly, the Assistant to Head of MI6 Stewart Menzies, was to say of the RSS\u2026. &#8220;a team of brilliance unparalleled anywhere in the intelligence machine.&#8221;<\/p>\n<\/li>\n<li><a href=\"https:\/\/youtu.be\/9_78oR9SZRc\" target=\"_blank\" rel=\"noopener noreferrer\"><strong><em>Precision microwave engineering: the fun of making your own components<\/em><\/strong><\/a>\n<p style=\"font-size: 12px;\">Neil Smith, G4DBN<br \/>\nThis presentation is about the joy of being able to imagine something in your head, mould it into a workable design using computer modelling and electromagnetic simulation, then turn that abstract idea into a working device or mechanism to help make amateur radio even more enjoyable. Neil works through the process of designing, modelling, machining and testing novel antenna feeds, elevation mechanisms for huge moonbounce antennas and tiny millimetre-wave antennas. He demonstrates how to use electromagnetic simulators, mechanical stress\/vibration modellers, thermal flow analysers and CAD tools to develop designs for antennas and amplifiers. Neil\u2019s machine shop is all manual, with lathe, milling machine, TIG welder, metal casting and metrology equipment. None of the machines cost more than a good transceiver, but the quality of work they can produce is very high. He shows the process of machining, measuring and testing some of the parts that he has designed, and tries to explain the enormous amount of sheer fun he gets from making things for himself and others. Machining, like radio, is purely a hobby for Neil, but he has made microwave parts for amateurs in more than 20 countries, and learned a huge amount of science, maths and engineering in the process. \u201cSelf-training in the art\u2026\u201d you might say.<\/p>\n<\/li>\n<\/ul>\n<ul>\n<li><a href=\"https:\/\/youtu.be\/_lfVOqPGQrI\" target=\"_blank\" rel=\"noopener noreferrer\"><strong><em>An obsession with antennas<\/em><\/strong><\/a>\n<p style=\"font-size: 12px;\">Callum McCormick, M0MCX<br \/>\nThis talk covers everything from very basic antenna modelling, through antenna shapes, to achieving impossible gain.<\/p>\n<\/li>\n<li><a href=\"https:\/\/youtu.be\/_JKrTXoNx6U\" target=\"_blank\" rel=\"noopener noreferrer\"><strong><em>DX-pedition to the South Orkney Islands<\/em><\/strong><\/a>\n<p style=\"font-size: 12px;\">Gene Spinelli, K5GS<br \/>\nDuring February and March of 2020 Gene, K5GS was among a team of amateur radio operators who set off on a journey that took them to Signy Island, located in the Southern Ocean at 60\u00b043\u2019S 45\u00b036\u2019W, part of the South Orkney Islands group. Departing from Punta Arenas, Chile, where they met the expedition vessel <em>Braveheart<\/em>, they travelled south-east for six days to reach the island. The team camped on the island for 14 days, operated radios 24 hours a day, and left the island as they found it, with no sign they were ever there. This was one of the last DXpeditions to take place before the COVID-19 pandemic hit and getting home proved to be tricky in several cases.<\/p>\n<\/li>\n<li><a href=\"https:\/\/youtu.be\/ymsHqZHMb9s\" target=\"_blank\" rel=\"noopener noreferrer\"><strong><em>DXpeditions on VHF: how to be successful at the other end of the pile-up<\/em><\/strong><\/a>\n<p style=\"font-size: 12px;\">Bernd Mischlewski, DF2ZC<br \/>\nMany radio amateurs dream of conducting a DXpedition at least once; being at the other end of the pile-up is very tempting. On the VHF bands\u2014particularly on the 2m band\u2014this can be achieved by comparably little effort. Even a rare grid square would count as a suitable place for such an activity, let alone a wanted DXCC. In this presentation Bernd, DF2ZC gives an overview of <em>dos<\/em> and <em>don\u2018ts<\/em> when planning for an activity: selecting the actual site, choosing equipment and antennas, travel, dealing with customs, licensing issues, etc. The presentation focuses on DXpeditions by single or max two operators\u2014which can be easily made a reality. However, it also includes general notes for multi operators and multi -and activities. Examples of successful VHF DXpeditions round off the presentation.<\/p>\n<\/li>\n<\/ul>\n<\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>Due to continuing uncertainty about COVID-19 restrictions, the RSGB held its Convention online for the second time.
