Sub-channel Receiver Mute
With dual receive capability, there will be
many instances when audio from both receivers
will be heard simultaneously. Aside from be oc-
casionally annoying, you might also miss impor-
tant information such as a QTH or callsign from
the desired station.
The mute feature enables the
channel receiver to always have priority. Any
station’s audio received on the sub-channel re-
ceiver is automatically and instantly muted,
only allowing main-channel audio to be heard.
This saves the inconvenience
of manually reduc-
ing the sub-channel audio using the
tons.
To enable this feature, simply press
MUTE appears just below the right
receiver frequency display. You still have
ter and
LED indications of activity on the
channel, but their audio will not be heard while
the main-channel is busy. Repeat the key se-
quence shown above to disable the sub-channel
receiver mute feature.

Repeater Splits
The FT-51R offers three methods to set up
split operation for repeaters:
manual, automatic and independently-stored
frequencies. Both manual and automatic
methods shift the transmit frequency above or
below the receive frequency by a programmable
offset, preset at the factory to 600 for VHF in
all versions, and 5, 7.6 or
1.2
for UHF, in
versions A, B and
C, respectively. Note that only
one offset at a time can be used with the manual
and automatic methods. Use the independent
transmit frequency method when you want to
store other offsets, such as frequencies of repeat-
ers with non-standard splits. This is described
later under
Storing Independent Transmit Frequen-
cies.
To activate the standard shift manually, Just
press for minus shift, and press
again for plus shift, and again to return to sim-
plex. A small
or sign appears above
either display to indicate the current shift direc-
tion, when activated.
