1st welcome to magic and the fun of satellites.
I do agree with Lucio IØLYL.
My half penny advice,start by one satellite . Read any thing wrote about it .e.g construction,size, power. etc . Use Social Media to gather any info, write on notebook all important details about it.Then start monitoring and tracking its Beacon, for sure after u master all those steps you can call CQ and later go to automazing your station in steps wise, eg Doppler correction,antenna auto tracking etc.
Enjoy it OM.
