@ REV switch Used to reverse the repeater shift (4600 kHz) to monitor a signal coming to a
REV repeater. Setting this switch to ON in simplex operation locks the displayed fre-
@) quency regardless of VFO, keyboard, and COM*.CH operations. (* European
and British versions excluded.}
@ TX OFFSET switch Used to set transmit frequency (+600 kHz) shifted from the displayed receive
frequency when transmitting.
AE: For operation other than that of a repeater, place this switch to the ‘‘S’’ posi-
tion. This equalizes the transmit frequency with the receive frequency.
“+4'" setting shifts +600 kHz; ‘’—"' setting shifts —600 kHz from the
receive frequency when transmitting.
This operation is only effective in VFO and MR (M1~M3) operations.
lf a shift frequency goes beyond the operating frequency range when depress-
ing the PTT switch to transmit, a beep will sound three times to indicate the
misoperation.
However, transmit frequency is emitted in simplex mode.
*With the optional TU-3 tone unit installed, either ‘‘+’' or ‘‘—'’ setting of the
TX OFFSET switch interconnects the TU-3 2nd tone frequency setting.

Note
that

should
be
less

(ARRAY)
:
:
Transceiver
performance
depends
largely on the type of antenna used.
For fixed station operation there are
ground plane antennas (omni-
directional) and Yagi antennas (uni-
directional). The Yagi antenna is
suitable for long distance operation
(DX) or communication with a
specific party.
(having excellent directivity and
antenna is generally used for local
operation.)
