3 beginner tips I've learned the hard way for operating the QO-100 ham radio satellite

I have to admit I do rush in with aspects of the ham radio hobby, I do try to jump the learning curve like an excited geek.
With the QO-100 ham radio satellite I saw the DX Patrol groundtstation and thought I could just buy a bunch of gear and begin to operate the satellite. I am learning as I go along especially focusing on the specs and details of the equipment I buy to work in the microwave bands. It's far less tolerant of cheap gear and sloppy practice.
I thought it would be useful to share my progression.
I'm a licensed amateur radio operator from the United Kingdom. My UA-cam channel features videos focusing on operating portable radio from various locations plus how to videos, tutorials, insights and conversations in the hobby.
