1) A special “RF Squelch” feature is provided on this ra-
dio. This feature allows you to set the squelch so that only signals exceeding a cer-
tain S-meter level will open the squelch. See page 13 for details.
2) If you’re operating in an area of high RF interference, you may need to con-
sider “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. If your friends have radios
equipped with DCS (Digital Coded Squelch) like your FT-252, you may try using
that mode for silent monitoring of busy channels.
