I am also active on QO-100 satellite. First QSO made on September 3rd 2023. I had pleasure to have QSO with EA3NJ on FT4. First CW and SSB QSOs were made with TO8FH (Mayoette) DX pedition in October.

My QTH is not optimal for satellite as there are lot trees and hills. QO-100 satellite is at quite low elevation here. On summer times I can mainly work FT8/FT4 and maybe little CW because birch leaves and sap decrades the signal quite lot. On winter time it is possible to make also SSB contacts but my signal is still usualy much weaker than others. Sometimes it is hard to go through pileup. I am glad that I have got many countries on QO-100 in these conditions. If you are going to DX pedition please listen for weaker stations. We are there trying to call you.

Here is the block diagram of my QO-100 station.
