OPERATION

SQUELCH ADJUSTMENT

To set the squelch, press the [F] 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 (“LVL 1” through “LVL 15”) that will just si-

lence the background noise. Do not use a higher setting 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 ra- dio 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 VX-177 has, try using that mode for silent monitoring of busy channels.

FREQUENCY NAVIGATION

The VX-177will 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 VX-177:

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 VX-177to be tuned toward a higher frequency, while counter-clockwise

rotation will lower the operating frequency.

If you press the [F] 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 VX-177.
