Set transmission mode in the radio control

Hello,
is there a possibility to set a certain transmission mode (in my case APT) as the default mode? When I’m using the Autotrack feature, the radio control automatically engages to the next satellite, but often to the wrong transmission mode. So can I somehow set APT as the default mode in Gpredict?

Thank you for your help in advance!

I solved the problem by removing the unnecessary transmitters from the files in ~/.config/Gpredict/trsp and leaving only APT.
