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, […]

Monitor for SG-Lab Power Amplifier
The 2.4 GHz 20W power amplifier from the Bulgarian company SG-Lab is widely used among the OMs (including QO-100 sattelite fans) [1]. In addition to the attractive price, this is also due to the excellent workmanship and delivery in the milled aluminum housing. The PA contains three internal directional couplers for measuring input, output and […]
ADALM-PLUTO tuning
The SDR Active Learning Module ADALM PLUTO from Analog Devices is used by many OM’s for working satellite QO-100. This is due to the attractive price and the excellent SSB-Modulation. No additional up- or down-converter are needed. Nevertheless some optimizations are possible. Installation in an aluminium housing avoiding radio frequency radiation Reducing frequency drift by […]
ADALM-PLUTO development kit for (not only) Es’hail-2 satellite
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 […]
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 […]
