This is a really good idea, an addition I would like: having the "radio" item (already dropping from military zombies) also be able to "tune" it into the frequency of a radio tower, everyone having that radio can then spawn in the radio tower radius. You would have the option in the radio tower to change the encoding, making already "tuned" radios useless on that tower. With this, friends can spawn under radio towers, but if a bandit kills one of the friends and they don't quickly change the encoding, he can spawn among them, making the possibility of backstabbing still possible, but only when you're not careful. Maybe one would need to add the radio to residential lootspawns to make it more available to people. What do you think?
