If you used to participate to a local network for rag chewing or an international one chasing a DX station, this is the tool you need.
Additionally there is a history tag in which NetManager keeps statistical records for previous sessions of the net. So you can see how much participation a call has or when was it the last time he broke in.
You will never forget names or other details for people who occasionally join the net. So you can address them always in a friendly way and that has a lot of fun. The software keeps detailed call database that you can update continuously.
