XPR 8400 CWID Problem
Posted: Mon Jan 21, 2019 12:19 pm
I manage an IP Site Connect system consisting of three (3) XPR 8400 repeaters on UHF and have recently noticed that they are failing to send CWID at the programmed interval. Model number is M27TRR9JA7BN running firmware version R02.09.00.03, codeplug version 19.00.03, and bootloader version R02.03.01.
This seems to have started since the last firmware update which I did in September. Prior to that firmware update, I had the CWID timer parameters set up as follows:
TX Interval (min) 15
Mix Mode Timer (min) 255
With that configuration running the previous version of the firmware (whatever the prior release was prior to R02.09.00.03) the repeaters would send ID every 15 minutes, usually at the end of an IP Site Connect beacon signal. Recently I was listening to my master repeater's output frequency in analog mode just to see how the co-channel interference situation was, and I noticed it was not identifying at all with the above configuration.
Thinking the failure to identify was possibly caused by the mix mode timer interval being set to 255 and thus disabled (which shouldn't matter for exclusively digital operation anyway) I changed the CWID timer parameters to the following:
TX Interval (min) 12
Mix Mode Timer (min) 14
I changed nothing else in the codeplug. After programming these parameters into each of the three repeaters, all of them restarted and began beaconing for 4320 ms every 60 seconds just like they always have. Then, when the CWID TX interval timer expired, they sent the CWID like they should have. But they only did it once and haven't done it since, despite several intermittent voice calls and beaconing every 60 seconds.
I would really like to rectify this situation ASAP. The two peer repeaters provide in-building coverage, but the master is at about 270 feet AGL and has a decent coverage footprint. Is this a problem with my programming or possibly a glitch in the R02.09.00.03 firmware?
Thank you for your responses!
