I didn't talk about imposing but an automated way to set SR limits per tuner. In any case, the user is allowed to change the limits manually.
Let's say Availink's delsys returns 0-60, Silabs 0-80 and BCMxxxx 2-45. What would be ideal is that these limits be set automatically, and if the user for some reason wants to change them manually, they have the liberty to do so.
This will also set a bar for any future tuner, who knows maybe one day there will be a new tuner that can range from -10 to 1 million.... Blindscan should detect the limits automatically.
Of course everything is a suggestion, and an idea, the doable part is another story...
