1) Show in text buffer a message telling you who's transmitting.
2) Rename ch1 to "all" , ch2 "country" ch3 "area" 4 "squad". Use ch # 1-100 for fields. So, if you tune in to Ch 24, then you will be xmitting to everyone inside a radius from 24.
3) get rid of the bip sound. ugh
4) option to have AH stop engine sound when receiving transmission.
