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.

RF 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 Menu Item

"Misc. Setup #2 [HOM/REV]. See page ??.

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 VXA-700,

and is very easy to activate.

The CTCSS setup involves two actions: setting the Tone Frequency and then setting of

the Tone Mode. These actions are set up by using the [1(VOR)TN] and [2(TO)CD] keys,

or Menu Items (SQL Type) and (TONE Set).

Press and hold the [1(VOR)TN] key for 3 seconds. This instantly recalls Menu Item

(SQL Type).

Press the [SEL(SET)] key again to enable adjustment of this Menu Item.

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 appearing while you rotate the

Note

DIAL selector knob in this step. We'll discuss the Digital Code Squelch system

shortly.

Rotate the DIAL selector knob in above step will occasionally appear "TSQ." When

"TSQ" appears, this means that the Tone SQuelch system is active, which mutes

your VXA-700'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.

When you have made your selection of the CTCSS tone mode, press the [SEL(SET)]
