DoE Hanford Update

I was able to spend a couple of days monitoring the goings on at the Hanford Site in Richland, Washington recently. I was primarily trying get an update on the status of a P-25 VHF trunked system that had shown signs of coming on the air the last two or three times I was in the area.

But this trip, I found no sign of any P-25 control channels! I don't know what happened to the system, but in past visits I have monitored a P-25 trunking control channel (System ID = def) on 164.3500 MHz and 164.4125 MHz, but nothing on any VHF frequency was found. I did hear the same, rapid Morse ID that appears on all the Hanford VHF frequencies on 164.4125, but no other activity.The other analog VHF radio nets for Hanford (Patrol, Fire, etc.) continue to operate as normal.

Another interesting thing is the UHF EDACS trunked system located at the Hanford Site is still up and running, but over two days I never heard a peep out of it. In the past this system has been fairly active during certain shifts with a lot of construction and maintenance operations. I've always thought it was mostly for contractors operations:

And new system that I saw on Radio Reference claims to belong to Bechtel, a major nuclear energy contractor. However, this system does not appear to be on the air at this time:
