Radio shack – this term does not need to be translated into another language. Every ham knows what this means because he has his own … Whatever it is, it is everyone’s pride. During contacts, we often wonder – what does our correspondent’s workplace look like? Below we present an open gallery of “radio shacks” […]
QCX transceiver QRP in SSB version
In the post “QCX transceiver QRP CW ” Piotr SQ5JUP described his experience with the QRP Labs mini-transceiver. Below is how to build a QSX SSB from the new QCX+ kit. The contents of the QCX+ kit from QRP-Labs http://shop.qrp-labs.com/kits/qcxp is shown below. The boards were assembled step […]
Happy Easter !
Health, happiness, good humor, tasty egg, wet dyngus and, above all, good luck in the SP DX Contest 2021!
Transceiver uSDX with Arduino Nano
Personally, I think that a “real” SDR radio is one where the radio signal is received by the antenna and then (possibly after passing through passive filtering circuits) is sampled by an analog-to-digital converter. Further processing of the signal takes place in the digital domain. However, the SDR category also includes other devices which to […]
Software Defined Radio with Arduino Nano
Arduino is a favorite toy for electronics enthusiasts. There are thousands of designs around these modules. Here’s the next one – the simplest and cheapest SDR receiver in the world! A “real” SDR radio is one where the RF signal received by the antenna is directly sampled by an analog-to-digital converter. Further processing of the […]
Terminal for non-contact body temperature measurement
The non-contact body temperature measurement terminal detects people with a fever that may be the result of COVID-19 infection. It has a unique face recognition algorithm, so it can be used to register people suspected of sickness and can be used to verify the identity of people and grant people the right to enter the […]

The PW-Sat2 satellite completes the mission, preparations for the PW-Sat3 launch are in progress Polish student satellite PW-Sat2 tested the sail for deorbitation, took thousands of photos, collected a lot of data. In January / February, it will burn in the atmosphere, ending the mission. In 2023, the PW-Sat3 alternately in orbit, the choice of […]
ADALM-PLUTO clocker
In the post “ADALM-PLUTO development kit for (not only) Es’hail-2 satellite”, the topic of the 40 MHz clock generator for Adalm-Pluto and 25 MHz for the LNB satellite converter was considered. The problem of the 40 MHz clock generator is somewhat solved by replacing the original micro-module of the generator with a more stable one, […]
ZOOM application for teleconferences
In the era of a pandemic, it is worth not to lose personal contact and conduct meetings using the teleconference applications. One of them is Zoom, which in addition to team conversation, allows you to conduct computer presentations visible to all participants. Until now, zoom has made remote learning easier for all students. Despite the […]
