On a Shari PiHatU, I’m trying to get rid of the dual-freq audio tone that is transmitted over RF by the Shari and received on my handheld radio when a user on a remote node unkeys. I can’t tell if this “touch tone” sound that I hear over and over when people on the remote node end their transmissions are transmitted by my Shari, or received over the network from the remote node I’m connected to. Is this possible? It’s getting on my nerves when monitoring a busy node.
I’ve looked up the courtesy tone how to on hamvoip.org and set nounkeyct=1 in rpt.conf, which just eliminates the “tail” I hear after I transmit. I’ve also tried changing some settings in the [telemetry] section, such as remotetx=… which didn’t change the tone-pair I hear when somebody remote unkeys. So I’m barking up the wrong tree here!
The [telemetry] stanza is the correct place to change the tones and remotetx= is the correct setting. Remember to restart asterisk after changing the values.
I don’t like that tone either and I change it to:
;remotetx = |t(1633,0,50,3000)(0,0,80,0)(1209,0,50,3000) ; local courtesy tone when linked Trancieve mode
remotetx = |t(1046,0,100,1024)
Changing remotetx had no effect (tried it again with reboot). But your post helped, I found that changing ct8 would change the tone. In my stock conf.rpt file, I found the following that led me to try this:
linkunkeyct=ct8
; sent when a network user unkeys. This
; method uses the mapped tone for all nodes.
I changed the definition to;
ct8=|t(700,0,75,512)
I cannot find the article now, but I was able to create a CT9 that had no tone designation and if that was selected there was no courtesy tone, but I found another one that I kind of liked and changed it to that.
