DESIGNATOR DMR P25 FCC..

[phantomcrow]

Is there a way to pull up a frequency and look at the FCC records online to see if the entity is using digital, NEXDEN, P25 or only analog?

 

[RaleighGuy]

Most of the FCC searches allow you to do this, go to the frequency tab and click on the frequency number for more info.

do you know if it also says that they are using encryption?

Encryption and usage is not under FCC control as long as otherwise permitted, thus it is not listed in FCC records, same as the NAC/RAN/Color/PL codes.

So they can use encryption without authorization? I thought there was some kind of permission required

Certain radio services allow it, others don't, if authorized in the licensed service it is automatically allowed should an entity choose to use it.

Yes. On an FCC ULS database search, click the Emissons tab and you'll see emissions designations listed on the column furthest to the right. See Radioreference wiki link here for a summary of emissions designations. Keep in mind that just because the emissions are listed on the license does NOT guarantee that the modes are indeed in use



This info is also available via the Radioreference license search...

Can anyone explain this then?

 

[RaleighGuy]

that is a emission designation

 

[Markb]

In my experience, the FCC emission designation does not always guarantee that they are in fact using said emission.

Because that is an older technology that had a different emission designator for encrypted audio. In P25 and DMR, it's the same emission either in the clear or encrypted.

Exactly.

The emission designaters that you see in the license only indicates what they are authorized to use, not what they are currently utilizing. You will find the occasional license that includes analog, P25 digital, DMR, and NXDN as well.

Can anyone explain this then?

It is an old proprietary emission designator that only Motorola required to implement Securenet encryption on NPSPAC plan channels.

If only the FCC would tell us the color codes, CTCSS, LCNs, RANs, etc. Now that would be some kinna dream.

They can't because that information isn't collected. It isn't required on license applications.
