KENWOOD TH-78A 144/440 MHz Dual Bander - The Repeater ...

REPEATER OPERATION1 Transmitter OffsetsAll amateur radio repeaters use a separate receive and transmit frequency. The receive frequency may beabove or below the transmit frequency. Most repeater configurations fall into one of the following categories.OffsetDirection VHF Band UHF Band+ +600 kHz +5 MHz- -600 kHz -5 MHz2 Selecting the Offset DirectionPress the SHIFT key. The transceiver will shift from one offset direction to the other, such as from + to -, orfrom - to simplex where no indicator shows. In the European version (UHF band), - change to - -.3 Automatic Offset SelectionThe TH-78A is programmed according to the standard ARRL (American Radio Relay League) Band Plan forrepeater offset direction. You can override this programming by using the SHIFT key as described in thepreceding paragraph.• To cancel automatic offsetPress and hold the BAND key and switch the power on.This operation switches automatic offset mode on or off.4 Manual Offset SelectionThe factory default sets the automatic offset frequency. You can select any offset frequency in the range 0 to99.9 MHz in 100 kHz steps.1) Press and hold the SHIFT/REV key and switch the power on.2) Press the F key for longer than one second, then press the SHIFT/REV key. The current offset frequencyis shown on the LCD.3) Rotate the Tuning control, and select the desired offset frequency.4) Press any front panel key to return to the normal frequency display. To return to the normal offset, resetthe VFO. (see page 15)NoteSelecting an offset frequency that would result in the radio transmitting outside its intendedrange will cause an error tone to be sounded and transmit to be inhibited. Reselect a validoffset frequency if this occurs.5 The Reverse FunctionSome repeaters use a' reverse pair', that is, the transmit/receive frequencies are the reverse of other repeaters.Page 24
