Es’hail-2 was launched in 2018. This geostationary satellite (fixed at a distance of appr. 36.000 km from earth) carries two “Phase 4” radio transponders operating on radio amateur frequencies (2400 MHz uplink, 10450 MHz downlink). A linear transponder has a bandwidth of 250 kHz and is intended for conventional analogue radio communications. Another transponder has a 8 MHz bandwidth and is designed for experimental (DVB) amateur television.
First ham QSO’s have been realized.
E.g., G0MGX was able to receive the satellite’s signals with an (ordinary) satellite dish:
I would like to do some experiments with an end-fed long wire antenna (appr. 20 m. length). One needs a balun for impedance matching. For a longwire antenne a 1:9 balun is recommended. I found a nice design on the website of PA3I: https://pa3i.jouwweb.nl/antenne
This weekend I visited the National Safety day in Culemborg.
Red Cross, the Navy, Army and Police showed their skills. Also the DARES was
present. DARES is an abbreviation for Dutch Amateur Radio Emergency Service.
I spoke with PA3GJM, Hans, the regio coordinator of DARES
in Gelderland-Zuid. He explained how, in emergency situations, communication
tru VHF/UHF and Short Wave can be established.
Interesting is the communications vehicle that also contains
equipment to route emergency e-mails via Winlink2000 / PACTOR protocol.
