Unidentified P25 Encrypted transmissions

[iDrBacon]

Was using DSD+ and SDR#, found a P25 signal. DSD+ reports that it's encrypted. Would look at the FCC Database but I have no idea how to use it.

Frequency: 409.537
I'm also noticing other P25 signals but they appear to have unidentifiable NACs. Will post more if I find more out.

That frequency is in a range normally used by Federal agencies, and as such, it would not be listed in the FCC database.

Several of the military bases' trunked systems in the S.A. area have frequencies in that frequency range.
