Right, Tom. The database is maintained by UTC but contributed to by NTIA and FCC. It was called for at a time when there were numerous Federal assignments in the band. Footnote 8 of our filing addresses it. Chris On Thu, Mar 10, 2016 at 1:49 PM, Tom Frenaye <frenaye@pcnet.com> wrote:

 UTC is clearly not going to want to disclose to us or anyone else the database of PLCs. They use PLCs for switching in the power grid and, as stupid as that is, using non-interference-protected technology for that sensitive purpose does worry FCC a good deal. Dave Sumner and I are of the view that UTC's database is probably not complete and if that is true they are not at all going to want to share it and reveal its inadequacies in any case.

Chris -

But UTC is required to share the database with the FCC (or is it with NTIA), isn't it? I still think we should request a copy of the database under FOI rules. Not that's we'd be successful...
