Unknown P25 BEE00.8A4 system. Indiana, Ohio, Maine?

The SL licenses do not cover the entire 700 MHz narrowband spectrum, that's why SY licenses are still required for the frequencies that are not part of the state allocation.

Do SL licenses cover every entity in the state, or just the state govt, itself? This system was bought by the Branch county government, yet there isn't a license listed for it.

SL licenses are issued to the State itself, and cover a subset of the 769-775 frequencies. If the State wants to allow county/local systems to use some of those frequencies, that's their prerogative.

Neither of those two frequencies are part of the state allocation covered under SL licenses, so it's not even a relevant discussion. AM909's post was incorrect when he stated that all 769-775 narrowband frequencies are covered under the SL licenses.

To cover the whole 700 MHz set, usually, as has been said you get both SL, and SY licenses. When the LWIN was first rolling out, it was a pita to find things as they used the SL/SY, but now there are local site licenses, and the ones for individual parishes/cities that rolled over into the LWIN etc...

What do you mean (e.g. WPTZ773 says 769–775 and 799–805)?

What do you mean (e.g. WPTZ773 says 769–775 and 799–805)?

Yes, I'm well aware of the frequency range shown on all SL licenses, however those licenses do not actually cover every frequency within the 769-775 spectrum. Many years ago the 700 MHz narrowband segment was cut up into various segments such as General Use, Interoperability, Low Power, Air-Ground, and State License allocations.

Only the frequencies which are specifically allocated to the states are covered under the SL licenses. Any other usage such as General or Air-Ground has to be licensed under SY or SG, depending on the implementation of the frequencies.

[AM909]

Thanks for that. Seems to be specified at 47 CFR Part 90 Subpart R (90.521–90.559).

 

[GTR8000]

90.529 and 90.531(b)(5) specifically.

The lesson here is that FCC licenses don't always paint the full picture, whether that be for which specific frequencies SL licenses cover, or the repeater outputs/inputs that are licensed on a conventional license. There is quite a bit of ambiguity out there. I think you know the point I'm trying to make here.
