[amsat-bb] Question for Gpredict Users

I'm new to using Ubuntu-Linux. I finally with a lot of outside counciling got FlDigi to run using either Hamlib or Flrig to handle CAT on my FT-847. I thought I was home free until I found that Gpredict would not control CAT on the radio. What am I doing wrong? Can anyone help? Linux is my only resource on this old XP P3 computer. Ubuntu runs great if I can only learn how to use command line Linus language hi hi! 73 Rick W2JAZ
