DX PACKETCLUSTERS MONITOR DX PacketClusters are networks which consist of nodes and stations who are interested in DXing and contesting. If one station finds a DX station on the air, they will send a notice to their node. This node then passes the information to its local stations through another node. The DX PacketCluster monitor function receives the packet data of the DX cluster and displays the contents. This transceiver can retain the latest information on up to 10 DX stations, but the memory will be cleared when the transceiver power supply is turned Off. If you have a TS-590S, TS-480HX/SAT, TS-2000/X, TS-570S/D, or TS-870S HF transceiver, you can connect the TH-D72 to the HF transceiver to use the DX PacketCluster Tune function. You can use this function to monitor the latest DX information in your area, be it cannot be used to send DX information to a node. ■ Connecting TH-D72 with the HF Transceiver In order to connect TH-D72 to the HF transceiver, you need to prepare three cables by yourself. The COM terminal on this transceiver accepts a 2.5 mm (1/10") 3-conductor plug. If necessary, use the cable (service part: E30-3400-XX) to modify the cable end of RS-232-C connector.

APRS – 26
DX PACKETCLUSTERS MONITOR
DX PacketClusters are networks which consist of nodes
and stations who are interested in DXing and contesting.
If one station finds a DX station on the air, they will
send a notice to their node. This node then passes the
information to its local stations through another node.
The DX PacketCluster monitor function receives the
packet data of the DX cluster and displays the contents.
This transceiver can retain the latest information on up
to 10 DX stations, but the memory will be cleared when
the transceiver power supply is turned Off. If you have
a TS-590S, TS-480HX/SAT, TS-2000/X, TS-570S/D, or
TS-870S HF transceiver, you can connect the TH-D72
to the HF transceiver to use the DX PacketCluster Tune
function. You can use this function to monitor the latest
DX information in your area, be it cannot be used to send
DX information to a node.
