New Dulles system?

[mejnetguru]

I see a new 700Mhz system added for Dulles Airport in the DB. Anyone know what this system is for? MWAA already had an 800Mhz system running for a long time but I monitor it from time to time and never observe any activity (tracks with lack of detail in the DB). I thought MWAA was moving (years ago) from their old P16 system to the P25 one but never moved for some reason, and I still hear them on the P16 all the time. Now another system???

Anyone have any insight? 800 for PS and 700 for non-PS maybe? And why haven't they moved in all this time?

To correct myself; new 800 system; 700 system was there before.

TG142 is 2272 on the old system. Divide by 16
This channel heard on both systems. Some comms are first heard on the new system a second prior to the new system, while other comms are only heard on the old.

The new 700 system i thought was for public safety due to its larger footprint. I havent heard anything on the new 700 system yet.

I have loaded IAD PD on 800 mhz system in to my Unication g5 pager. Works great! Are there any other id's that are working? I have put OPS and FD in with no rx. Suggestions?

I'm seeing a few more channels showing up like Reagan PD and baggage handlers. I'm watching on Pro96Com. A few channels of the old system are being rebroadcast om the new. No radios are affiliating on the new system.

I have only been able to receive the Toll road site so far from my location. The site always alerts my G5 with "Entering Site Trunking". I haven't received any talkgroups yet.

Myself and 2 others have not received anything on Dulles/Mwaa 800mhz system using G5 pager in past week or so. Wonder if they were just testing that system for awhile?
