M7ENP Adventures & Experiments

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

Greetings! I'm excited to share with you some information about my SatNOGS ground station located in the UK . I built it from scratch, using a self-built UHF/VHF turnstile antenna and a Raspberry Pi for data processing. In this blog post, I'll provide you with a comprehensive overview of my SatNOGS ground station, including the satellite signals it receives, and how it receives and decodes those signals. First, let's talk about the satellites that my station has received. The satellites that I've managed to receive data from include NOAA-19, FOX-1A, and the International Space Station (ISS). NOAA-19 is a critical weather and environmental monitoring satellite that provides valuable data for forecasting. It orbits the Earth in a polar orbit, passing over the poles at an altitude of approximately 870 km. The data that I've received from NOAA-19 has been useful in helping me to better understand the environment and climate around me. FOX-1A, on the other hand, is a sma

The Key to Stronger Signals Ham radio enthusiasts understand the importance of having a strong antenna system in order to effectively communicate with other operators. But with so many different types of antennas on the market, it can be difficult to know which one is the best fit for your needs. In this blog post, we'll break down the different types of antenna systems available for ham radio use and help you determine which one is right for you. First, let's start with the basics. An antenna is essentially a device that converts electrical energy into radio waves, and vice versa. When you transmit a signal, the energy is sent through the antenna, which then converts it into radio waves that can travel through the air. When a signal is received, the radio waves are picked up by the antenna and converted back into electrical energy that can be understood by your radio. There are many different types of antennas available for ham radio use, including vertical, horizontal, and di

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

 ARISS SSTV Event Set for April 11-13, 2022 From the International Space Station, an ARISS Slow Scan TV (SSTV) event is planned (ISS). The event is scheduled to begin on April 11 at 16:30 UTC for setup and operation and will finish on April 13 at 12:00 UTC. These are approximate timings that may fluctuate based on crew availability. Images will be downlinked at 145.8 MHz +/- 3 KHz for Doppler shift, and the planned SSTV mode of operation is PD 120. This event will commemorate Cosmonautics Day and Women in Space. Radio enthusiasts participating in the event can publish and see images in the ARISS SSTV Gallery at https://www.spaceflightsoftware.com/ARISS SSTV/.

  RSØISS - SSTV activity Thursday April 7 start about 08:00 GMT, stop about 15:35 GMT* Friday April 8 start about 08:40 GMT, stop about 16:10 GMT* Description: Russian cosmonauts on the International Space Station (ISS) are planning to transmit Slow Scan TV images on 145.800 MHz FM using the SSTV mode PD-120. The transmissions are part of the Moscow Aviation Institute SSTV experiment (MAI-75) and will be made from the amateur radio station RS0ISS in the Russian ISS Service module (Zvezda) using a Kenwood TM-D710 transceiver.  Thursday April 7 start about 08:00 GMT, stop about 15:35 GMT* Friday April 8 start about 08:40 GMT, stop about 16:10 GMT* *Dates and times subject to change.

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.
