[App_rpt-users] Fwd: COR signal getting confused

[REDBUTTON_CTRL]

Ok In a bid to understand what it is you think is wrong let me clarify 
from what you are saying below.
Your node is set up for duplex=1 (half duplex with courtesy beep and 
tail) right?
And the problem you are seeing is the node will not receive a signal 
when it is transmitting the courtesy beep or tail - right?

If the above is correct, then this configuration cannot receive a signal 
while it is transmitting. This is normal for this configuration.
If your radio is portable or mobile radio, then your radio can only 
receive  or transmit but not both simultaneously.  So in duplex =1 mode 
the URI assumes your receiver is active if the node isnt transmitting. 
So the node ignores all receiver activity while its transmitting. Once 
the tail is gone then it will listen to thereceiver cor line.

For some reason from you explanation below you are expecting the node to 
receive in full duplex. Unless the radio you have connected is capable 
of full duplex, this wont work. If the radio connected to the URI is a 
pair of radios or a duplexed base station and if you set the duplex 
setting to duplex=2  in rpt conf and duplex =1 in usbradio then it will 
receive while its transmitting.

Hope I  understand this right and this helps.
