[arm-allstar] 1750Hz tone burst

[Patrick Perdue]

I don't live in an area where tone burst is used, but as I understand 
it, that should only be used to wake up the repeater after it has been 
idle for a while, not for every transmission.

So, maybe something with the rptinactimer in combination with the ptt 
event such that it only happens when the node has had no traffic for a 
while, and only once until the timer is tripped again. Set the timer for 
whatever value is used by the repeater before it goes to sleep after 
being activated by a tone burst.

Have the rptinactimer call a macro that runs a bash script which does 
something like:

#!/bin/bash
txtone=1
You can probably just do this directly from the cmd line on the macro 
and not bother with an external script, now that I think about it.

Then call a script on ptt that plays the 1750hz tone to the repeater (I 
assume this would be local only) and only if txtone=1, then immediately 
sets txtone to 0 so it doesn't trip again until the timer goes off. You 
may need to use holdofftelem=1 and a short value for telemwait in 
rpt.conf for best results there, with duplex set to something other than 0.

Or, you could, instead, do

touch /tmp/txtone

from the timer, and look for the presence of that file in the ptt event 
script, deleting it after playing the 1750hz tone.

Just a thought, no idea if it would actually work in practice.
