According to the original mod, if the mod is installed after satellites have been launched, the game should update all placed radars on the map after launching another satellite. This is not the case. Currently have to manually delete and replace each radar for the stats to change.

This is probably because the game treats the vanilla radar and the new radar as separate entities. Either fixing the mod so that the change affects vanilla radars instead of creating a new item or making it so that the modded radars are tagged as an upgrade target for vanilla radars would suffice.
