[arm-allstar] Duplex setting

[Steve Agee]

*Hi John,

The part most folks do not understand is what happens when you do NOT 
define it in your /etc/asterisk/rpt.conf file. So, when you do NOT 
define it by adding a line, then it defaults to a value of "duplex=2". 
This is a full duplex repeater situation. So, for your 1998 node, you 
must add the line to tell it this is a simplex node. Since it is an RF 
link to another repeater, you probably want to add "duplex=0" which will 
force it to a half-duplex mode with no courtesy beeps, hang time, and no 
cw or voice identifiers .... just like a true simplex conversation would 
be. For node 50191, you don't need to do anything, unless you want to 
somehow deviate from the normal full duplex repeater situation. As for 
node 1999 .... well is this a voting receiver or what? Never has made 
much sense to me to dedicate a node to RX only or TX only, but there 
must be something else going on here that you did not disclose earlier, 
perhaps a split site situation or something similar.
