This may happen to the SDS200 also as well as others models, but I've confirmed it on my SDS100.
Randomly I turn my SDS100 on and it will show it's sitting on a frequency and will show "DATA", but the system ID, site number and RFSS are blank and it won't receive any calls. Today I confirmed it finds an active IV&D (data) channel being used before it finds a CC and stays on that. A power cycle usually clears this, assuming it finds a CC before a data channel. I don't recall my x36HP series ever doing this. I've seen others report this symptom as well.
I guess a fix is to delete all but the known CC's as those shouldn't be in the IV&D rotation I believe (but I'm not positive about, I'll have to check).
Maybe this can be added to the "list".
