need some help pls.
i have tm5400+ motorised 80cm. how would i find and save new satellite , and transponders. the sat that are on my receiver were all ready on it .

I always put it in via clarke tech studio editor, then send to the machine on a usb stick, But this is because i put multi sats at the same position so each major package it listed as a sat.
You can also add by going into satelite set-up, tick one of the blank ones name and position and save
