This is very strange, as if someone program to disrupt a talk group.

·         Tonight: Had good communication on SMP ARC SoCal, then the DMR repeater it didn’t respond anymore (No Repeater found),

·         Tried PAL ARC SoCal it worked for a few times and quit. 

·         Tried SDL ARC SoCal and that worked for a few QSO with Bill K6HMS and that quit after a few transmission. 

So I got on to ZumSpot and that continues to work and had QSO with KM6ZPO he was using BlueDV.

Interesting points:

·         At 9:37 pm a few minutes ago I tried SDL ARC SoCal and it works again.

·         Tried SMP RC-SDG PRI at 9:41 pm and it works.

·         Tried PAL ARC SoCal and it now works after 5 consecutive key ups.

Had a really strange situation about some time ago (and a few FW revisions back), on the AT 578 where I got on the DMR through a repeater and the Radio just turned off by itself.  I believe there maybe a remote control function via RF (similar to a repeater) that can manipulate the radio from remote… Will have to investigate.  But the problem went away with the following newer FW installed.
