Adalm-Pluto (Analog Device) SDR radio starter kit was received for experiments by courtesy of Michał Trzaskowski from Richardson RFPD. This device gives completely new possibilities when it comes to cooperation with the first geostationary amateur satellite Es’hail-2. To name a few: thanks to the large bandwidth of the receiver (up to 6 MHz) it is […]

Xiegu G90 – Transceiver for QRP operations, and digital emissions
QRP work has many advantages, especially during holiday trips. I have been practicing it for years – especially from the Greek islands. However, I have a problem: the elephant has stepped on my ear which I use to receive CW. Last time I was actively practicing CW on the RBM-1, as an operator of “Operation […]
Es’hail-2 (or QO-100) for beginners
I bought a 80 cm satellite dish (16 Euro), a converter (4 Euro), installed it on the roof and set it up on the satellite (Dish Pointer was very helpful for azimuth and elevation finding). In our conditions, a 80 cm satellite parabola is a reasonable minimum when it comes to the receiving antenna. I […]
HF5L Remote
The HF5L station has been adapted for remote access via an internet connection. HF5L Remote is initially intended for standard contacts in the 3.5 and 7 MHz bands. HF5L Remote is currently a 100 W low-power station. It is equipped with a Yaesu FT-897 transceiver with an external AT-897 antenna box, as well as a […]
SP9VFD antenna system for EME
EME communications have fascinated Rafał SP9VFD from the very beginning of his amateur radio hobby, ie since 1991, when he received the first license at the age of 15. At the time, his favorite reading was UHF guide “Poradnik Ultrakrótkofalowca” by SP6LB. However, it was only in 2007 that he managed to carry out the […]
Our satellite activity
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 […]

DX from space
Amateur telemetry reception from ARTSAT2 interplanet probes: DESPATCH and Shin-en2. Authors: Piotr SP5ULN, Michał SQ5KTM, Piotr SP5MG, Łukasz SQ5RWU. Introduction Bands above 50MHz are often treated only as local FM communication channels. Here and there in the radioamateur environment, the opinion is repeated that in this frequency domain nothing particularly interesting is happening, excluding only […]
