The IARU Region 1 Field Day (SSB) Amateur Radio Contest is a great idea for a joint club activity, with friends or individually. It is a chance to test yourself in many areas: field work, emergency power supply, design, antenna construction. Above all, it is good fun and often new experiences. If the contest is […]
GreenCube is aimed at demonstrating an autonomous biological laboratory for plants cultivation on-board a CubeSat platform. The satellite project is managed by the S5Lab research team at Sapienza University of Rome https://www.s5lab.space/index.php/greencube-home/. The spacecraft has been launched on 13 July 2022 and it has been deployed in Medium Earth Orbit (MEO) at approximately 6000 km […]
In March 2021, a revised version of Adalm-Pluto Revision D was released. Version C was identical to version B (without the 2 blue wires). Analog Device has released new information regarding revision D. Since the firmware is the same between revision D and revision C, the firmware identifies and recognizes revision D hardware as revision […]
Many have heard of it, but few know what it is about. And it’s worth knowing. The M17 project is often called the future of digital radio in the global amateur radio community. For Poles, it is a reason to be proud, because the idea was created at the turn of 2018 and 2019 in […]

After a series of meetings on VHF subjects in our HF5L club, we started to prepare for work through amateur satellites. March 8, 2019 Piotr SQ5JUP made the first contact from home QTH via FOX-1D satellite (AO-92) on FM using the X300 antenna + duplexer MX-72A + IC-9100. As you can see, you can do […]
Some transceivers have a microphone input adapted to the electret microphone and some to a dynamic one. It is not possible to replace them due to design differences. The electret microphone contains a FET transistor in the capsule, which must be supplied with DC voltage in the same wire as the audio signal. The FT-991 […]
August 1 is another anniversary of the outbreak of the Warsaw Uprising in 1944, so important to all Poles. This is an excellent opportunity to present the heroic struggle of the soldiers of the Uprising in terms of military radio technology. Thanks to my colleagues SP3LD and SP3CSD, I learned about Louis Meulstee’s publications on […]
