[App_rpt-users] Echolink connection announcement Volume

[Jon Rorke]

So what you are looking for is the announcement level to duck to 50 % 
when somebody is talking at the same time? But normally full level when 
nobody is talking? Is that what you mean when you say the repeater is in 
use?

If so, right now DIAL and ACID distros dont do that.

What I have done is set telemdefault to2 and holdofftelem=1.

Setting Telemdefault to 2 makes the telemetry announce if a command is 
initially sent from the node as per normal, then after a time of 
inactivity the telemetry goes quiet so you wont hear any connections if 
somebody connects.

This is good for ongoing nets so that incoming stations joining don't 
distract conversations.

The holdofftelem=1 just holds off any pending announcements its going to 
make until the transmitting station unkeys.

If you are looking for the announcements ducking lower when somebody 
keys, only the XIPPAR distro suports that.

Our issue boils down to the fact all the volumes are the same, announcements and user voice, and we'd like to have the announcements about half the volume when the repeater is in use. I'm looking at holdofftelem=1 as well as http://docs.allstarlink.org/drupal/node/126 to see if we can achieve a workable compromise.
