[arm-allstar] tones on transmission

In the node stanza in rpt.conf that you want to eliminate courtesy tone add - 

Note that courtesy tones are there for two reasons. One is to force users to wait until after the tone to speak. This 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.

Subject: [arm-allstar] tones on transmission

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.

My setup is using a Pi2 > USB sound card > HT radio.

I tried adjusting some of the .conf files but haven’t found
the setting yet.
