Hi All; I have noticed the following since adding a remote base (TM-271) to my system (so the system comprises of a main repeater node (operating half-duplex into an analog controller) and a second fob connected to the TM-271).... Randomly, the audio from my main node (connected to the analog controller) disappears... i.e., app_rpt does not 'hear' the audio from the repeater, it *does* see the COS signal, so the result is an unmodulated carrier out to the connected links. Interestingly, the audio from the remote base works fine - i.e., if I hop over to the RB, I can carry on the conversation with folks connected to the main repeater node. An rpt reload does not fix this. When I restart the Asterisk service, then things are fine and again will run for a random period of time (could be one day, or sometimes 3 or 4 days) until the next hit. I've tried disconnecting the RB node, so that it is not connected to the main node at all, and this does not seem to make a difference. This morning, I have commented out the RB stanza in rpt.conf and its associated stanza in usbradio.conf - will be interesting to see if this re-occurs with just the one node connected. ... wonder if anyone else has seen this, and if so, what the fix was / is? Thanks, Ramesh.
