LEO / ISS Satellite Groundstation since March 2022

LEO/ISS Satellite Groundstation
The goal is to install a satellite 2m/70cm Groundstation at home in order to make active radio contacts with the current and future LEO satellites and the ISS.
There are currently a few LEO satellites in the space which you can work with SSB or FM.
The challenge is the operation in one SAT cycle (5-15 minutes) with the doppler shift etc.
I'm using the S.A.T Tracking Box to control my YAESU G-5500DC AZ/EL Rotor.
Below are many links regarding Ham-Radio Satellites ....

Es’hail 2 Geo-Satellite QO-100 / QRV since 6.3.19

Qatar’s Es’hail-2 Satellite 2019 - OSCAR 100
Es'hail-2 - Successfully launched into orbit (15. Nov. 2018)
The eagerly awaited start of the Es'hail-2 took place on 15/11/2018 at 20:46 as planned and successfully. This is the beginning of a new era in satellite broadcasting for us radio amateurs.
OSCAR 100 (QO-100) is QRV since February 14. 2019.
Qatar’s Es’hail-2 satellite will provide the first amateur radio geostationary communications that could link amateurs from Brazil to Thailand. The satellite is positioned at 25.5 degrees East.
Es'hail-2 coverage areaEs’hail-2 will carry two “Phase 4” amateur radio transponders operating in the 2400 MHz and 10450 MHz bands. A 250 kHz bandwidth linear transponder intended for conventional analogue operations and an 8 MHz bandwidth transponder for experimental digital modulation schemes and DVB amateur television.

Oscar 10 Satellite Operation 1984 - 1985
These are some impressions from my OSCAR 10 SAT-Operation between 1984-1985. I used the ICOM IC-211 E for 2m (10 Watt) for the Downlink and the KENWOOD TR-9500 70cm (10 Watts) with a Home-Made Amplifier (50W) for the Uplink. I used the 14-element Yagi antenna from Tonna for (2m) and the 23-element Yagi for (70cm).
A self developed Commodore C64 application was managing my home built automatic SAT Antenna-Moving solution which was able to follow the OSCAR 10 at any time. A home made Pre-Amp controller unit for 20m and 70cm was managing the RX/TX flow for SAT operation.
