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(EMG)] key. You’ll notice that the display has
shifted to the repeater uplink frequency. Press the [HM/RV(EMG)] key again to cause
operation to revert to normal monitoring of the repeater downlink (output) frequency.

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-7R, and is very easy to activate.

: CTCSS setup involves two actions: setting the Tone Frequency and then
setting of the Tone Mode. These actions are set up by using the [8(TONE)] key, or Menu
Items (TSQ/DCS/DTMF #1: SQL TYPE) and (TSQ/DCS/DTMF #2: TONE SET).
1.
Press the [MON/F] key, then press the [8(TONE)] key. This provides a “Short-cut”
to Menu Item (TSQ/DCS/DTMF #1: SQL TYPE).
2.
Press the [MAIN] or [SUB] key so that “TONE” appears on the display; this
activates the CTCSS Encoder, which allows repeater access.

: You may notice an additional “DCS” icon appearing while you press the
[MAIN] or [SUB] key in this step. We’ll discuss the Digital Code Squelch system
shortly.
3.
Press the [MAIN] key in step “2” above will occasionally cause “SQL” to appear
adjacent to the “TONE.” When “TONE SQL” appears, this means that the Tone
SQueLch system is active, which mutes your VX-7R’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 areas.
4.
When you have made your selection of the CTCSS tone mode, rotate the DIAL one
click clockwise to select Menu Item (TSQ/DCS/DTMF #2: TONE SET). This Menu
selection allows setting of the CTCSS tone frequency to be used.
5.
Press the [BAND(BND DN)] key to enable the adjustment of the CTCSS frequency.
6.
Press the [MAIN] or [SUB] key until the display indicates the Tone Frequency you
need to be using (ask the repeater owner/operator if you don’t know the tone
frequency).
