The Squelch
Next we want to look at the squelch. First notice from the
uplink illustration of Figure 12, that both receive and transmit
tones are turned off (R-OFF and T-OFF) which is NOT correct.
One of the major benefits from using a PL tone is that
atmospheric or other electromagnetic media that occurs in
nature will not activate the repeater. It is also a guard against
other repeaters in the distant region that might otherwise
activate the repeater needlessly.
Touch the [
SQL]
button which causes the repeater to show the
screen illustrated in Figure 13. It is now shown that RX and TX
squelch tones are off.
Touch both RX and TX SQL one at a time until each shows
“
TONE.
”
Press [
BACK
] twice (2x) taking you to
…
Press
[SQL]
(see Figure 3). This takes you to the A-side equivalent of what we saw in the B-side Figure 8.
As we did in that earlier slide. Set the squelch to its lowest value which is still greater than zero
—
1.
Press [
BACK
] once to return to the home page.
Press
[A SETUP]
and
[F]
taking you to the uplink screen
illustrated in Figure 12. Not shown in the figure, notice now
that the Squelch button looks different reflecting the fact
that the repeater is now programmed to utilize the tones in
squelch functionality.
Press the [
BACK
] button two times to return to the home
screen.
Do the same programming for the B-Channel which will be
used exclusively for remote control on a special frequency.

Figure 13 Here is where the repeater may be told
that it is to use sub-audio tones. The frequencies of
the tones themselves may or may not have been
already set. Those are separate functions.
