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 […]

STORE-LOGGER – Wireless temperature and humidity control system in warehouses

The STORE-LOGGER system is designed to microclimate monitoring (temperature, relative humidity of the air, door opening) in rooms where products sensitive to climatic conditions are stored. It is indispensable wherever applied ISO, GDP and GMP quality systems require professional documenting of cold supply chain and storage of temperature-sensitive products. More information about the STORE-LOGGER can […]

LB-532 – Temperature and humidity recorder with USB interface

Hytherograph LB-532 is a precise recorder of relative humidity and air temperature (with resolution of 0,01°C). It is powered by a replaceable long-life lithium battery, which enables uninterrupted operation of the device for many years. The data collected in the device’s memory after connecting it to the computer via USB, are presented by the Logger […]

This time the station was located near Brok, Poland. […]

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 […]

GNI-r6 controller for RAS, SPX AZ/EL and BIG-RAS azimuth/elvation rotators

A new rotator controller model is available for rotating VHF antennas in azimuth and elevation. Below is a quick guide for the GNI-r6 antenna rotator controller. Introduction. The GNI-r6 controller supports one dual rotor with DC motors for azimuth and elevation rotation that has pulse outputs (pulser or reed switch). Antenna rotation is possible with […]

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 […]

GNI-r5 controller for RAU, RAK, BIG-RAK and RAEL rotators

Rotary antenna rotator controller. A new model of the GNI-r5 antenna rotator controller is available. Compared to previous versions, it has new features and a new steel casing. The following is the shorted operating manual for the GNI-r5 antenna rotor controller.           Introduction. The GNI-r5 controller supports one rotor with pulse […]

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 […]
