OK... this change is just fine.. and even though I am a member of a squad that frequents NOE missions, I actually do support the change.... with a couple of... 'enhancements'...
1> If Radar is down at a base, it should revert back to the original 12K distance, and increase height to about 200ft or so for the base to flash.
2> Mountains should block base flashing altogether. If there is no direct line of sight between the top of the radar tower and your location, you should not appear on the scope and the base should not flash UNLESS another plane/GV on that bases' country DOES have icon range on you.
3> The rules for town flashing/scope blips should apply to the radar tower in town, and base radar should be based on the radar tower in base.
Make sense?
