Page 26: Chapter 6 Operating Through Repeaters
Repeaters, which are often installed and maintained by radio clubs, are usually located on mountain tops or other elevated locations. Generally they operate at higher ERP (Effective Radiated Power) than a typical station. This combination of elevation and high ERP allows communications over much greater distances than communications without using repeaters. -
Page 27: Programming Offset
The default offset frequency on the VHF band is 600 kHz no matter which market version; the default on the UHF band is 5 MHz (TH-D7A) or 1.6 MHz (TH-D7E). 1 Press [F], [5] to select “F–5 (OFFSET)”. PACKET96BCONDUP 2 Press [UP]/ [DWN] to select the appropriate offset frequency. -

Note: APRS packets, which are generated via various methods, include various codes instead of group codes. Using “All calls” allows you to receive packets which include the following codes. -
Page 78: Programming A Packet Path
PROGRAMMING A PACKET PATH A packet path specifies how APRS data should be transferred via one or more repeaters. A repeater, which is used for packet transfer, is commonly called a digipeater. This came from a digital repeater. A digipeater is usually located on a mountain top or high building. - Page 79 Let us describe four basic methods for editing a packet path. Method 1 (Specific path): Program the call signs of one or more digipeaters in the sequence of transfer relay; ex. “KD6ZZV,KF6RJZ”. Method 2 (Generic path): Program “RELAY” and/or “WIDE”; ex. “RELAY,WIDE”. In this example, APRS data is transferred to any relay-type digipeater near your position first, then to any wide-type digipeater.
