[App_rpt-users] Repeat on/off states

[Darrell Wick]

Goal: Establish local repeat on/off states

Definition:
In the repeat 'on' state, the local receiver repeats to the local 
transmitter as do any links. In the 'off' state, the local transmitter 
does not transmit. The intent is to switch to the off state after a 
period of local transmitter inactivity, terminating any active links at 
that time. Switching back to the on state would require either a local 
DTMF code or receipt of an incoming link connection.

Several approaches were tried to achieve this. At first it was hoped the 
controlstates rptena/rptdis would work, but examining app_rpt.c 
(V0.199), it appears rptdis is a synonym for the system disable cop 
command 3 (both set txdisable = 1)(while rptena appears to be slightly 
different than the system enable cop command 2). Further, txdisable = 1 
prevents incoming link connections, thus preventing new link connections 
changing the state from off to on.

There doesn’t appear to be an activity timer for the local transmitter, 
but the link activity timer does provide a usable timer function, so 
long as this node always establishes a link when switching to the on state.

Any suggestions or help much appreciated.
