Page 7: Operating Through Repeaters
OPERATING THROUGH REPEATERS Repeaters are often installed and maintained by radio clubs, sometimes with the cooperation of local businesses involved in the communications industry. Compared to simplex communication, you can usually transmit over much greater distances by using a repeater. Repeaters are typically located on mountain tops or other elevated locations. -
Page 8: Selecting A Tone Frequency
203.5 Refer to the settings below for offset directions: 206.5 210.7 TH-D72A: 218.1 Under 145.100 MHz: 225.7 145.100 ~ 145.499 MHz: – 600 kHz offset 229.1 145.500 ~ 145.599 MHz: No offset... -
Page 9: Transmitting A 1750 Hz Tone
TRANSMITTING A 1750 Hz TONE Most repeaters in Europe require that a transceiver transmit a 1750 Hz tone. On a TH-D72E, simply pressing [CALL] will transmit this tone. It is also possible to program [1750] on the front panel as a [CALL] key for transmitting the 1750 Hz tone. -
Page 10: Memory Channels
In Memory channels, you can store frequencies and related data that you often use. Then you need not reprogram the data every time. You can quickly recall a programmed channel by simple operation. A total of 1000 Memory channels are available for bands A and B. SIMPLEX &... -
Page 11: Storing Odd-Split Repeater Frequencies
STORING ODD-SPLIT REPEATER FREQUENCIES Some repeaters use a receive and transmit frequency pair with a non-standard offset. To access those repeaters, store two separate frequencies in a memory channel. You can then operate on those repeaters without changing the offset frequency you stored in the menu. 1 Set up a simplex channel by following steps 1 to 6 of “STORING SIMPLEX AND STANDARD REPEATER FREQUENCIES”, above. -
Page 12: Naming A Memory Channel

Page 31: Gps (Global Positioning System)
The GPS receiver receives the radio signals transmitted from the GPS satellites. The receiver measures the time duration between when the signal leaves the satellite and when the signal arrives at the GPS receiver. Knowing this time allows calculation of the distance that the signal traveled from that particular satellite. By receiving multiple signals from different satellites and doing this distance calculation multiple times, the intersection of the spherical surfaces that represent the respective radius distances to the various satellites will determine a single point. -
