Squelch Adjustment; Frequency Navigation - Yaesu FT-270R Operating Manual

To set the squelch, press the [ F/L ] key, followed by the MONI switch just below the
PTT switch on the left side of the transceiver.
Now rotate the DIAL (outer knob) to find the lowest

setting ("
silence the background noise. Do not use a higher set-
ting than necessary, or sensitivity to weak incoming
signals will be degraded.
Press the PTT switch momentarily when you've made
the new setting; this will return you to normal operation (without having transmitted).
1) A special "RF Squelch" feature is provided on this radio. This feature
allows you to set the squelch so that only signals exceeding a certain S-meter
level will open the squelch. See page 18 for details.
2) If you're operating in an area of high RF pollution, you may need to consider "Tone
Squelch" operation using the built-in CTCSS Decoder. This feature will keep your radio
quiet until a call is received from a station sending a carrier which contains a matching
(subaudible) CTCSS tone. Or, if your friends have radios equipped with DCS (Digital
Coded Squelch) like your FT-270R has, try using that mode for silent monitoring of busy
channels.
The FT-270R will initially be operating in the "VFO" mode, a channelized system which
allows free tuning throughout the currently-selected operating band.
Three basic frequency navigation methods are available on the FT-270R:
1 ) Tuning Dial
Rotation of the DIAL (outer knob) allows tuning in the pre-programmed steps established
for the current operating band. Clockwise rotation of the DIAL causes the FT-270R to be
tuned toward a higher frequency, while counter-clockwise
rotation will lower the operating frequency.
If you press the [ F/L ] key momentarily, then rotate the DIAL,
frequency steps of 1 MHz will be selected. This feature is
extremely useful for making rapid frequency excursions over
the wide tuning range of the FT-270R.
