The radio could have been a good idea with 0 as the default channel if there wouldn't be so much children and idiocy around. (Post above me has a good example in it)
Radio is cool as it is now in my opinion. Neverthless there's one thing which i think is very annoying not only for me:If you loot NPCs who have radios within their inventory its always set on channel "0" by default. Especially if you take the loot from like four critters for example, you have to manually switch each of them off to not be annoyed by the blahblubb of the default radio channel.So, simple solution would be to just set a random channel to NPC-Radios or (maybe even better) set em on "Off" by default.I know it's a minor thing here but little improvements also count ..Greets B.
