If you used to participate a local network for rag chewing or an international one, chasing a DX station, this is the very tool you need. It will help you to manage all the traffic of stations that break in or leaving the frequency. It is very convenient especially if you deal with big groups.
Additionally there is a history tag in which DxNetManager 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.
Doubtlessly you will love it too from the very beginning you will start using it. Finally it is freeware. Go here, download and enjoy it.
