I think whats going on here is there are stations using a simplex
channel not intending to use the Allstar node. However the node is
hearing one or both of the stations and keying up with its courtesy
tone. <br>
<br>
Perhaps a simple solution here is to put the node on PL (CTCSS). So
if the simplex stations are not using tone, they wont bring up the
node. <br>
If they intend to use the node then use PL on transmit to access the
node.<br>

<br>
When you setup a simplex node - connect allstar to a radio you
are in effect putting Allstar on that frequency. By default
Allstar responds with a courtesy tone to tell users on that
frequency that Allstar is there and active. It does not
transmit over anyone only when they stop transmitting like you
would hear on a repeater. If it actually does transmit over
someone then your COS is probably not working properly. The
polarity might be reversed. To test -<br>
<br>
From the L:inux prompt go into the Asterisk client -<br>
<br>
asterisk -rvvv<br>
<br>
Key and hold the PTT of your radio that talks to your node
radio. You should not see anything yet. Unkey the radio. You
should see the hungup message in the display. If you are
seeing the hungup message on key down then COS polarity is
reversed. If you are not see it at all either way then COS is
not working.<br>
<br>
To reverse COS polarity edit /etc/asterisk/simpleusb.conf <br>
<br>
Look for the 'carrierfrom' line <br>
<br>
It can either be usb for positive going on signal or
usbinvert for negative going (around 0 volts) on signal <br

of an RF transmission when COS drops the repeater
stays keyed for the delay period and then the

I think what you were hearing was normal. Courtesy
tone is meant to indicate end of transmission and
the other party can talk. If you are talking over
it then you are keying up too fast. <br>

courtesy tones are there for two

eliminates cutoff of audio due to
delays in the system. you should
always wait 2-3 seconds to transmit.
Fast keying is not a good thing in
Allstar. It also does not allow others
to break in. The other reason
especially on simplex odes is to show
that the RX actually heard you. On
repeaters Allstar is often used as the
controller and thus the courtesy tone
would be for the repeater. Most
repeaters have courtesy tones.<br>

<div dir="ltr">I am trying to
eliminate a “courtesy tone” on
my setup. It
seems that each time the system
hears a radio transmission; it
has to transmit
a tone about 2 seconds after the
end of the reception. Sometimes,
it will
transmit over the person trying
to talk (RF) back. This occurs
when there is no
one connected to the node.<br>
My setup is using a Pi2 > USB
sound card > HT radio.<br>
I tried adjusting some of the
.conf files but haven’t found
the setting yet.<br>
