[arm-allstar] Multiple repeaters one node number

[Doug Crompton]

Chris,

 There are a number of ways this could happen. One is that someone was
connected in monitor mode. An example would be you are connected to someone
in monitor mode and then they connect to you. The monitored station then
bleeds through to them and they have no idea you have that node connected
in monitor mode. They then try to call the station you have connected in
monitor mode and their audio does not get to them, monitor means no TX.
Couple this to a larger connected network and it can be bonkers! So you
have to be aware of this. Also occasionally nodes get into one way audio
situations similar to monitor mode. This is a problem we have been looking
at. The answer in this case is to disconnect and reconnect the offending
node. So not sure what happened in your case but it is something to be
aware of.
