It's being used by a lot of TIS stations these days. No licensed
full-power operation there.

Just the Canadians in Montreal and Toronto. (The "CFOS Collingwood"
that shows up on many 1610 lists was never built; it was applied for
as a repeater for CFOS 560 Owen Sound, but never made air and has
been deleted by the Canadians, though not from the FCC's list.)
The problem with using 1610 as a full-power frequency is that it has
to clear the adjacent-channel restrictions to existing stations on
1580, 1590 and 1600, and there are a LOT of those out there. The din
from all those 1610 TISes doesn't help matters, either.
Since the KALT license was returned, I get the impression the FCC
(which is in no hurry to authorize new X-banders of any sort, anyway)
has more or less given up on the idea of using 1610 as a full-power frequency.
