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 station. This combination of elevation and high
ERP allows communications over considerable distances.

SELECTING AN OFFSET DIRECTION (SHIFT)
The offset direction allows your transmitting frequency to be higher (+) or
lower (–) than the receiving frequency.
Press [SHIFT] to select an offset direction.
• Each time you press [SHIFT], the offset direction changes as follows:
Simplex operation (no offset) ➡ “ ” ➡ “ ” ➡ Simplex operation (no offset)
• If you are using a TH-K40E (E type) model, the offset direction changes as follows:
Simplex operation (no offset) ➡ “ ” ➡ “ ” ➡ “ ” (–7.6 MHz) ➡ Simplex
operation (no offset)
If the offset transmit frequency falls outside the allowable range, transmitting is
inhibited. Use one of the following methods to bring the transmit frequency within
the band limits:
• Move the receiving frequency further inside the band.
• Change the offset direction.
Note: While using an odd-split memory channel or transmitting, you cannot change the
offset direction.
