RXCLUS is a tool for licensed radio-amateurs and SWL's who are interested in DX'ing and are QRV in packet-radio. It makes possible to receive informations transmitted on the PacketCluster system without having to establish a connection to a cluster node. It identifies the frames sent to cluster users, and also those exchanged between two cluster nodes with a special protocol. This possibility is especially interesting for the SWL's during the night time as it makes possible the reception of cluster informations even if no user is connected on the local node ! With no connexion established, DX, WWV and ANN informations (with a connexion: also Talk) are recognised among all the frames heard on the monitored frequency and are the only ones to be displayed. Each information is displayed only once, even if it is repeated many times on the frequency because several users are connected or there are many retries. So you get the same result as if you would be connected to the cluster, but without additional traffic on the air and with no link failures problems. It is not a problem if the monitored frequency is shared with other packet services (Mailbox, and so on).
