Code:
mob/var
    headset = 0
    frequency = 1

mob
    proc
        HeadSet(mob/M in world,msg as text)
            if(M == src)
                return
            if(M.headset==1&&src.headset==1&&M.frequency==src.frequency)
                M << "[src] says: [msg]"




mob/verb/Say(msg as text)
    view() <<"[usr] says: \"[msg]\""
    call(/mob/proc/HeadSet)(usr,msg)

obj
    Radio//defines the object sword
        icon = 'headset.dmi' //defines which icon file to go to
        verb
            Activate()
                if(usr.headset == 0)
                    usr << "You turn on your headset radio."
                    usr.headset = 1
                else
                    usr << "You turn your headset radio off."
                    usr.headset = 0
            Change_Frequency()
                if(usr.headset == 1)
                    var/head = input("What frequency?","Current Frequency: [usr.frequency]") as num
                    usr.frequency = head
                else
                    usr << "Turn your headset radio on first."
                    return


Problem description:
runtime error: Cannot read null.headset
proc name: HeadSet (/mob/verb/HeadSet)
usr: Situs67 (/mob)
src: null
call stack:
HeadSet(Situs67 (/mob), "final test...")
Situs67 (/mob): Say("final test...")

The Idea is to make like...a radio that can be used to communicate with everyone that has a radio and has it turned onto the same frequency using the normal Say verb.

You're using call() wrong. Instead do a for loop of mobs in the world who have the same frequency as yours and display the message to them.

In response to Kalzar
Alright. How should the code look?
