New APCO-25 Federal Freq in OKC

[Gilligan]

I've been listening to 163.650 for federal activity. What I was getting was primarily data bursts every two minutes. Then I got confirmed APCO-25 digital. My 246T is showing a hint of a 251 DPL tone, but I'm attributing that to the digital and thinking there really is no DPL. Can someone w/ a digital scanner listen to this freq and try to identify. It's a common freq for Border Patrol, INS, or Immigration, but it could be something else. Thanks.

PS. It's active w/ digital comms right now.

It does seem to be P25, but I'm not hearing any audio now. It's like someone is just kerchunking the repeater.

That's an old border control frequency which should be used by the new DHS agency they call ICE.

The US BP is very active where I live on both the MPSCS system and on their conv freqs - their conv freqs tend to be p25. It leaves me to believe they think p25 is encrypted.

I'm getting a few digital signals coming every 10-15 minutes with data bursts every 2 minutes exactly. It's not real active, but there is some digital there.

I still haven't heard any voice on there - just data bursts.

The few times I think I have heard border patrol, they have been encrypted P25 (with some awesome repeaters somewhere - they had like 75+ mile range (listening on 796 going down interstate)!)

I have the 396 locked on that freq - I'll let you know if I hear anything in P25.

Data can be transfered in P25 also. I don't know how long those data bursts are. I know a "page" over P25 is VERY short - on a repeater, you would probably only hear the "tail" after your scanner unsquelched. In direct, my scanner doesn't even really pick it up (because it's such a short burst).
