Many repeater systems require that a very-low-frequency audio tone be super-
imposed on your FM carrier in order to activate the repeater. This helps prevent
false activation of the repeater by radar or spurious signals from other transmit-
ters. This tone system, called “CTCSS” (Continuous Tone Coded Squelch Sys-
tem), is included in your FT-65R/E, and is very easy to activate.
1.
Press the F/W key, then press the
[
1
]
or
[
0] key to enable selection of the
CTCSS/DCS mode.
2.
Press
the
[
] or
[
] key
so that “TONE” indication appears on the dis-
play; this activates the CTCSS Encoder, for access to repeaters requiring a
CTCSS tone.
3.
Pressing
the
[
] or
[
] key
one more “click” in step “2” above will cause the
“TSQL” notation to appear. When “TSQL” is displayed, this means that the
Tone Squelch system is active, which mutes your FT-65R/E’s receiver until it
receives a call from another radio sending out a matching CTCSS tone. This
can
help
keep
your
radio
quiet
until
a
specic
call
is
received,
which
may
be
helpful while operating in congested areas of the band.
4.
When you have made your selection of the CTCSS tone mode, press the
PTT
switch to save the new setting.
5.
Press
the F/W key, then press the
[
2] key to enable adjustment of the
CTCSS frequency.
6.
Press
the
[
] or
[
] key
until the
display indicates the Tone Frequen-
cy you need to be using (ask the
repeater
owner/operator if you don’t
know the tone frequency).
7.
When
you have made your selec-
tion, press the F/W
key momentarily to save the new settings and exit to
normal operation.
This is different than the usual method of restoring normal
operation, and it applies only to the conguration of the CTCSS/DCS fre-
quencies.
