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 and hold the key for 2 seconds.
You’ll notice that the display has shifted to the repeater
uplink frequency. Press the key again to cause opera-

link (output) frequency.
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 trans-
mitters. This tone system, called “CTCSS” (Continuous
Tone Coded Squelch System), is included in your VXA-
700, and is very easy to activate.
The CTCSS setup involves two actions: setting the Tone
Mode and then setting of the Tone Frequency. These ac-
tions are set up by using the and keys, or Menu
Items (SQL Type) and (TONE Set).
r Press and hold the key for 3 seconds. This instantly
recalls Menu Item (SQL Type).
r Press the key again to enable adjustment of this
Menu Item.
r Rotate the DIAL selector knob so that “T” appears at
the bottom right corner on the display; this activates
the CTCSS Encoder, which allows repeater access.
Note: You may notice an additional “DCS” icon ap-
pearing while you rotate the DIAL selector knob in
this step. We’ll discuss the Digital Code Squelch sys-
tem shortly.
