I can understand some people's disdain for echo , noise toys and Roger beep. but why the hate for talkback? Nobody is going to hear it on the other end of the radio. Don't like it then don't use it. I use mine to adjust my mic and to hear if I have a microphone problem or some else going wrong with radio system.
I don't always talk to myself but when I do i use talk back.
