This morning, at around 5:45 am, I saw something curious on my 996xt on the freq used for the Civil Defense in Ledyard, 153.9650 MHz. P25, LNK. I sat there for a few minutes and listened. I don't know who they are or what they were talking about.(came into to the conversation in the middle of it apparently) The people talking made references to contacting someone and setting something up. This on and off converstion last till about 6:05 am then stopped. Any ideas?
