Antenna Installation
The supplied antenna provides good results over the entire frequency range of the transceiver. However, for enhanced reception on certain non-Amateur frequencies, you may
wish to connect an antenna designed specically for that frequency range, as the supplied antenna is necessarily a compromise outside the Amateur band, and cannot be expected to
provide high performance at all frequencies.
To install the supplied antenna, hold the bottom end of the antenna, then screw it onto the mating connector on the transceiver until it is snug. Do not over-tighten by use of extreme force.
Notes:
Never transmit without having an antenna connected.
When installing the supplied antenna, never hold the upper part of the antenna while
screwing it onto the mating connector on the transceiver.
If using an external antenna for transmission, ensure that the SWR presented to the
transceiver is 1.5:1 or lower, to avoid excessive feedline loss.

Checking the Repeater Uplink (Input) Frequency
It often is helpful to be able to check the uplink (input) frequency of a repeater, to see if
the calling station is within direct (“Simplex”) range.
[
To do this, just press the
repeater uplink frequency. Press the
normal monitoring of the repeater downlink (output) frequency. While you are listening
on the input frequency to the repeater using the
blink.
The conguration of this key may be set either to “REV” (for checking the input frequency of a repeater), or “HOME” (for instant switching to the “Home” channel for
the band you are operating on). To change the conguration of this key, use Set Mode

CTCSS Operation
Many repeater systems require that a very-low-frequency audio tone be superimposed
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 transmitters. This tone system,
called “CTCSS” (Continuous Tone Coded Squelch System), is included in your
and is very easy to activate.

band.
1) You may notice a “REV TN” indication on the display while you rotate the
DIAL knob in this step; this means that the Reverse Tone Squelch system is
active, which mutes your FT-257’s receiver (instead of opening the squelch)
when it receives a call from the radio sending a matched CTCSS tone. The
“ ” icon will blink on the display when the Reverse Tone Squelch system is
activated.
2) You may notice the “DCS” indications on the display while you rotate the
DIAL knob still more. We’ll discuss the Digital Code Squelch system (for
“DCS”) later.

normal operation, and it applies only to
the configuration of the CTCSS/DCS

Your repeater may or may not re-transmit a CTCSS tone - some systems just use
CTCSS to control access to the repeater, but don’t pass it along when transmitting. If
the S-Meter deects, but the FT-257 is not passing audio, repeat steps “1” through “4”
above, but rotate the DIAL so that “TSQ” disappears - this will allow you to hear all
trafc on the channel being utilized.
Another form of tone access control is Digital Code Squelch, or DCS. It is a newer,
more advanced tone system which generally provides more immunity from false paging than does CTCSS. The DCS Encoder/Decoder is built into your
eration is very similar to that just described for CTCSS. Your repeater system may be

Tone Search Scanning

You must be sure that your repeater uses the same tone type (CTCSS vs. DCS).
Some repeaters do not pass the CTCSS tone; you may have to listen to the station(s)
transmitting on the repeater uplink (input) frequency in order to allow Tone Search
Scanning to work.
To scan for the tone in use:
1. Set the radio up for either CTCSS or DCS Decoder operation (see the previous discussions). In the case of CTCSS, “ ” will appear on the display; in the case of

useful during Search-and Rescue situations, where is important to stay in contact with
other members of your group.
Both stations must set up their DCS codes to the same code number, then activate their

Whenever you push the

Whether you talk or not, the polling every 15 or 25 seconds
will continue until you de-activate ARTS™. Every 10 minutes, moreover, you can have
your radio transmit your callsign via CW, so as to comply with identication requirements. When ARTS™ is de-activated, DCS will also be deactivated (if you were not using it previously in non-ARTS™ operation).
If you move out of range for more than one minute (four pollings), your radio will sense
that no signal has been received, three beeps will sound, and the display will revert to

During ARTS™ operation, your operating frequency will continue to be displayed, but
no changes may be made to it or other settings; you must terminate ARTS™ in order to

DCS Code Inversion
The DCS system was rst introduced in the commercial LMR (Land Mobile Radio)
service, where it is now in widespread use. DCS is sometime referred to by its different
proprietary names, such as DPL® (Digital Private Line®, a registered trademark of Motorola, Inc.).
DCS uses a codeword consisting of a 23-bit frame, transmitted (subaudible) at a data
rate of 134.4 bps (bit/sec). Occasionally, signal inversion can result in the complement
of a code to be sent or received. This prevents the receiver’s squelch from opening with
DCS enabled, as the decoded bit sequence would not match that selected for operation.
Typical situations that might cause inversion to occur are:
Connection of an external receiver preamplier.
Operating through a repeater.
Connection of an external linear amplier.
Note that code inversion does not mean that any of the above listed equipment is defective!
In certain amplier congurations, the output signal (phase) is inverted from the input.
Small signal or power ampliers having an odd number (1, 3, 5, etc.) of amplication
stages may result in inversion of a transmitted or received DCS code.
While under most circumstances this should not occur (amplier designs and industry
