If it's C&W or Glentel it will probably not be on their public systems, more likely a dedicated
one like the old Moto system.
Ironically, my first trunked scanner BC235 was purchsed at a fleamarket in Kingston. It
has been useful for trunking until very recently, as most 800MHz Moto systems have gone
off the air, or will shortly...
Try scanning 422-425, 451-455 and 460-465 for DMR (TRBO) sounds. If you can decode it,
so much the better.
TAFL shows UHF DMR channels for C&W. Glentel has a bunch of licenses, not sure they
do Kingston; not enough time to sort through all of them, though somebody might want to.
In my experience, CloseCall doesn't work for DMR at least on simplex/inputs.
