I’ve ran across this twice. I’m probably overlooking the reason behind this but I just don’t get the purpose of doing this. What is it supposed to serve to do this? Who is the guy doing this? This one is done inside a General Lee. There’s a switch to cut off the talkback so I don’t get why it’s on a relay. Is it to reduce feedback from someone what? It looks to me like it’s just something to get your money and make you feel like it’s accomplished a great deal.
