VX-3R Operating Manual
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 [HM/RV] key. You’ll notice that the display has shifted to the repeater uplink
frequency. Press the [HM/RV] key again to cause operation to revert to normal monitoring of the repeater
downlink (output) frequency.
R.F. Says: The configuration of this key may be set either to “RV” (for checking the input frequency of a
repeater), or “HM” (for instant switching to the “Home” channel for the band you are operating on). To
change the configuration of this key, use Set Mode Item 36: HM/RV. See page ??.
CTCSS/DCS/EPCS Operation
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 VX-3R, and is very easy to activate.
R.F. Says: CTCSS setup involves two actions: setting the Tone
Frequency
and then setting of the Tone
Mode
. These actions are set up by using the [MODE] key or Set Mode Items 79: SQ TYP and 86: TN FRQ.
1. Press the [F/W] key, then press the [MODE] key. This provides a “Short-cut” to Set Mode Item 79: SQ
TYP.
2. Rotate the DIAL knob so that “TONE” appears on the display; this activates the CTCSS Encoder,
which allows repeater access.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
3. Rotation of the DIAL knob one more “click” in step “2” above will cause the “T SQL” notation to appear.
When “TSQL” is displayed, this means that the Tone SQueLch system is active, which mutes your
VX-3R’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 specific call is received, which may be helpful while operating in
congested
R.F. Says: 1) You may notice an additional “DCS” icon appearing while you rotate the DIAL knob in this
step. We’ll discuss the Digital Code Squelch system shortly.
2) You may notice “RV 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 VX-3R’s receiver when it
receives a call from the radio sending a matched CTCSS tone. The “TSQ” icon will blink on the display
when the Reverse Tone Squelch system is activated.
3) You may notice “PR FRQ” indication on the display while you rotate the DIAL knob in this step, this
means that User programmed Reverse CTCSS Decoder mutes your VX-3R’s receiver when it receives
