She was explaining to me as I was talking to her the conversation would start with a strong voice then quickly quiet down to maybe less that half volume and at the time we are just a few miles apart. I have no clue as to how DCS would affect that but I remembered the issues I had with a couple handhelds. All I know is after switching to CTCSS its been perfect. I'm familiar with the different types of tones and I used to program our radios for the police department but our channels didn't use any with DCS. I've been programming my radios for a long time and I did have a couple of Wouxun handheld radios I couldn't trust to open up every time if I used DCS. I live in a rural area anyway and don't see having any problem using CTCSS anyway so I'll stick with that. When we were on vacation in Galveston, several times we had to change channels and CTCSS at times to find a quiet channel.
