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.

The transceiver restores the frequency display after approximately 10 seconds pass or when you press any key.

When duplicate DX cluster data is received, the frequency display is not interrupted. “dD” and a call sign will appear at the bottom of the display.

To scroll through up to 10 sets of DX information, press [LIST] twice, then press [UP]/ [DWN].

Comment

• Press [LIST] to restore the frequency display.

Note:

The information is cleared when the transceiver power is turned OFF.

This transceiver beeps each time it receives new or duplicate DX cluster data. You may access Menu 1–5–3 (BEEP) to change this setting. The default is “ALL”. See the table on page 63.

Before tuning to a PacketCluster node, switch the APRS Beacon function OFF {page 74}; otherwise, unintentional APRS packet transmission will annoy PacketCluster nodes and stations.
