Using a PTT switch in conversation with aviation radios has taught me that its not very user friendly. Once you've pushed your button, you can't hear if anyone else is talking. People 'step-on' each other and a listener can't hear either one.
Also, you really have to be quick to get-in your call right after someone else has finished. There has to be a better way.
THE IDEA IS TO USE A CELLPHONE AS A TWO WAY RADIO. YOU WILL UNDERSTANDBETTER HAD YOU BEEN INVOLVED IN A EMERGENCY EXCERCISE. THE IDEA IS NOTTO OVERIDE A CONVERSATION BUT TO SELECTIVELY CALL YOUR GROUP. ONEINDIVIDUAL WILL CONTROL THE ENTIRE GROUP.
Some CDMA services offer that. Bell Mobility in Canada, calls their version 10-4.
