I am in process of implementing a transponder pattern recognition.
It allows to automatically identify the frequencies of transponders. This is the ultimate blind scan, as the signal doesn't even need to be locked and frequencies are determined instantly on the whole frequency range!
The next step is to match the frequency pattern against a database of known transponders, i.e. satellite transponders. This allows signal (satellite) identification much before the signal can be locked.
Of course, I need to clean up this functionality and include an export function to save the transponder list.
Here are some pictures of the current state:
