→Asterisk CLI Commands
The chan/voter channel driver is the interface between Asterisk and the [[RTCM/VOTER Interfaces | RTCM/VOTER]] radio/repeater hardware interface. It allows receiver voting, simulcast transmitters, or just a plain repeater interface when used with the appropriate hardware.

=Basic Information On How chan_voter Works=
Each node has a number of potential "clients" associated with it. In the voter.conf file, each stanza (category) is named by the node number that the clients specified within the stanza are to be associated with. Each entry consists of an arbitrary (relatively meaningless, just included for easy identification purposes within this channel driver, and has nothing to do with its operation) identifier equated to a unique password. This password is programmed into the client. '''All clients must have unique passwords, as that is what is used by this channel driver to identify them.'''

=voter.conf Variables=
This is a dump of variables found in the source... they'll need to be fleshed out with some descriptions and applications:
<pre>
linger (uses default if not specified)
plfilter <--this doesn't seem to work?
hostdeemp
duplex (defaults to 1)
mixminus (defaults to 0)
streams
txctcss
txctcssfreq
txctcsslevel (defaults to 62)
txtoctype (defaults to none?, options phase and notone)
primary
isprimary
thresholds
gtxgain (defaults to default_gtxgain)
password
sanity
puckit
dyntime
buflen
utos
port
bindaddr
These are options allowed for each site:
transmit
master
adpcm
nulaw
dynamic
gpsid
buflen
nodeemp <-- this works, bypasses the deemp filter (sets the switch H)
hostdeemp
noplfilter <-- this works, toggles the pl filter in the rtcm (sets the switch L, default seems to be H so the filter is in)
prio
</pre>
Also, if non-GPS-based operation is all that is needed, just the use of redundancy within the clients is sufficient, and does not require any use of the server redundancy features.

=Voter Recording and Playback=
chan_voter has the ability to record VOTER streams by the channel driver live on the air (using the 'voter record' command in Asterisk). This also records time-stamped data and the voted receiver at that particular time along with RSSI readings. This can then be played back using the VoterPal GUI JAVA applet.
==How to setup playback==
# Download the [https://allstarlink.org/voterpal/VoterPal.jar VoterPal application].
# Download the [https://allstarlink.org/voterpal/lib/appframework-1.0.3.jar appframework-1.0.3.jar] and [https://allstarlink.org/voterpal/lib/swing-worker-1.1.jar swing-worker-1.1.jar] files. Place these in a folder called lib in the same directory as the VoterPal application
# Run VoterPal.jar. You may come across issues with running Java such as security permissions. Most of these can be allowed.
# Once running, you will see the applications GUI. File > Open to select your voter data files. A bunch of test files have been made already to test [https://allstarlink.org/voterpal/datafiles/ here]
[[File:Voterpal.png|left|thumb|549x549px]]
'''Reset'''
Resets the file back to start
'''Play'''
Plays the recorded file
'''Stop'''
Stops the current playing file in it's current position
'''CTCSS Filter Enable'''
Removes CTCSS hum from any recorded audio stream
'''File Play Position'''
Drag this slider to skip
'''Activity'''
This will show time-stamped information including RSSI of the selected VOTER client within the recorded data stream
'''Voter Clients'''
This will show the real time voted client. This is also dependent of the Mode setting
'''Mode'''
Various modes can be selected in VoterPal
0 - Normal Voting Mode
1 - Randomly pick which client of all that are receiving at the max RSSI value to use
> 1 - Cycle thru all the clients that are receiving at the max RSSI value with a cycle time of (test mode - 1) frames. In other words, if you set it to 2, it will change every single frame. If you set it to 11, it will change every 10 frames. This is a serious torture test.
< 0 - Any value less than zero will force select the Voter Client (i.e. -1 is the first client, -2 is the 2nd client)
==Node Configuration==
As mentioned above the Asterisk CLI is as follows -
* voter record instance_id [record filename] - Enables/Specifies (or disables) recording file for chan/voter
Where
- instance_id = voter number instance
- record filename is the filename of the recording to be stored
A script can be made and placed in cron.hourly which will run every hour. Every time the above command is run in Asterisk, it creates a new file. An example of such a script is below
#!/bin/sh asterisk -r -x "voter record instance_id /tmp/voter-record"`date +%F-%H-%M` >> /var/log/voterrecordlog
the /tmp/ directory can be substituted for mounted USB HDD.
