Any info about the US Army Europe P25 network?

[dk5ras]

Hi,

during the last years it appears that the US Army has established a P25 trunking network throughout some European countries. In Germany there showed up transmitters in the 141/142 MHz band, uplink frequencies however unknown. Some use quite high sites with good coverage, others are close to US Army installations and replace the conventional 80MHz FM and 140 MHz P25 systems that were in use during the last 15-20 years.

Moving from different local solutions of limited interoperability to a common system appears to be not the worst move

Maybe someone can tell a bit more about this?

With best regards

Ralph.

Any system ID's found yet ?

Probably very similar to the existing systems implemented here in the US (two examples below)

United States Department of Defense (14C) Trunking System, Nationwide, Multi-State

United States Air Force (157) Trunking System, Various, Multi-State

uplink may vary by country (host) but maybe
141/142 using 137-139 (uplink - also known as input) or 148-150.8 (well known Conus MilOps band)

It is on this system. System ID 169. The database entry is missing a couple P25 sites for Ramstein AB, Aviano AB in Itlay, Moron AB in Spain, etc.

Seems that Ralph hasn't logged in since his question in January.

The system that is linked on radioreference is missing more than 'a couple' of sites - most of the UK sites not just the European ones. Looks to be old data.

Back in 2020 I heard a P25 signal from presumably the UK during atmospheric conditions (I'm from the Netherlands). From my logs:

414.0750 MHz
Site:BEE00.169-2.3 NAC:163 NL:2.4

Edit:

I also found logs from 2019, also presumably from the UK:

406.4250 NAC 165
407.4750 NAC 165
