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. They generally operate at higher ERP (Effective Radiated Power) than a typical TX: 144.725 MHz station. This combination o

TRANSMITTING A 1750 Hz TONE AUTOMATIC SIMPLEX CHECKER (ASC) Most repeaters in Europe require that a transceiver While using a repeater, ASC periodically monitors the transmit a 1750 Hz tone. On a TH-D72E, simply pressing strength of signals you receive directly from the other [CALL] will transmit this tone. It is also possible to stations.

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.

CTCSS/ DCS/ CROSS TONE CTCSS You may sometimes want to hear calls only from specific persons. The Continuous Tone Coded Squelch System (CTCSS) allows you to ignore (not hear) unwanted calls from other persons who are using the same frequency. To do so, select the same CTCSS tone as selected by the other persons in your group. A CTCSS tone is subaudible and is selectable from among 42 tone frequencies. DCS Digital Coded Squelch (DCS) is another application which allows you to ignore (not he
