[arm-allstar] tones on transmission

[Doug Crompton]

The courtesy tone goes out to any local device connected to the node. So it would go out over the connected radio. For simplex operation when COS drops indicating an RF station stopped transmitting there is a delay (settable) and then the node TX keys and the courtesy tone is sent. For full duplex at the end of an RF transmission when COS drops the repeater stays keyed for the delay period and then the courtesy tone is sent.

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.

The issue I was having was no one was using/ logged into or using the node. The conversation was between 2 parties, radio to radio (rf only) and the system was keying over the start of their conversation.I changed the setting and it seems to be gone.Thanks!Ryan

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

nounkeyct=1

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.

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.
