Does your DR3000 have 8Mb or 32Mb memory? The only (correct) way to tell, is to look at the back of the repeater.
One of the labels (see above) has the repeaters' TANAPA number on it .
If this TANAPA number is one of the following, then the repeater has 32Mb memory:
PMUE3084BAEAA [DR 3000 UHF2 (1-40W)]
PMUE2390CAEAA [DR 3000 UHF1 (25-40W)]
PMUD2091CAEAA [DR 3000 VHF (25-45W)]
PMUD2092CAEAA [DR 3000 VHF (1-25W)]
PMUE3017CAEAA [DR 3000 UHF1 (1-25W)]
MTR3000 repeaters only have 32Mb memory.
The TANAPA number shown in the CPS is truncated (last 3 digits missing) and is not a clear indicator of memory size.
