DX PACKETCLUSTERS MONITOR

1DX PacketClusters are networks which consist of nodes

2and stations who are interested in DXing and contesting.

3If one station finds a DX station on the air, he (or she) sends a notice to his (or her) node. Then this node

4passes the information to all its local stations besides

5another node. This transceiver can display received DX

6information and hold the latest information on up to 10 DX stations. Use this function to monitor the latest DX

7information in your local area. You cannot send DX

8information to a node, using the function.
