Getting operational on the QO-100 geostationary amateur radio satellite was originally my project for the winter of 2019/20 but the coronavirus lockdown has given me the opportunity to finish my project.
This is a description of my setup for QO-100, using a LimeSDR mini, cheap 2W 'wifi' amplifier, and POTY antenna with a 90cm dish. I also give a brief introduction to the satellite for beginners. Please be aware there are many other ways of getting QRV on the satellite - the equipment here shouldn't necessarily be your shopping list!
Correction: The 3cms downlink is at 10.489.5GHz, not 10.6GHz. Everything I say here still applies, however!

Excellent, so would you have a block diagram of what's required, and how everything is connected, in order to get setup..

not sure if the effective radiated power is really 500 watts, but nice video!

Nice presentation, I could just like to know the minimum requirement of dish diameter. I'm living near the Arctic Circle (66° north) Norwegian coast, I already have an 120cm fiber glass offset laying around but I'm not sure if the gain will be sufficient for working the QO-100? Any suggestions are appreciated. 73's de LA3DNA Leif

So why does it use such high frequencies rather than something more common like 70cm? Is it to do with penetration of the atmosphere?

Being rather pedantic - It is the QO-100 TRANSPONDER on the Eshail SATELLITE !! This comment may appear to be very nit-picking but I believe being incorrect like this causes newcomers a great deal of confusion !!

Speaking of safety, could 2 watts of microwave radiation do any harm to the body other than heat it up a couple of fractions of a degree? In this cotext, I'm sure there's nothing to be afraid of.

Hi Anton, you're probably right but in the UK we not have to calculate compliance distances and ensure nobody can get within a certain distance of an antenna. For 2w at 13cm with a 1m dish at 1m AGL, the compliance distance is 4.3m, so we have to ensure nobody can stand within 4.3m of the dish.
