They're back on TDMA, it would appear.
There was a problem with some APX radios shutting down/rebooting, that happened around the same time NWCD went FDMA, perhaps it just took this long to get the radios fixed. Just speculation.
That would make sense. I moved last month, so I can't check Unitrunker to confirm. Had a feeling it wouldn't be permanent though. I also thought I saw a post somewhere that said Motorola sent out an update to subscriber units sometime last week. Probably unrelated, but it's possible that fixed it.
