I have searched the forums and am well aware of the tunnels in the hampton roads area using 453.850 for their operations. I am interested in PL tones for them so that it will be much easier to sort out all the intertangled voices that one hears during rush hour daily. I also have pinned down the PL tones for all that I know of. Does anyone have any more PL tones or corrections to this list? Is there more than just tunnel activity for this frequency IN THIS AREA? (Peninsula, Southside, Etc.)
453.850 100.0 Hz = Monitor Merrimac MBT (Confirmed)
453.850 127.3 Hz = Hampton Roads BT (Confirmed)
453.850 156.7 Hz = Midtown Tunnel (Confirmed)
453.850 192.8 Hz = Downtown Tunnel (Confirmed)
The ones marked confirmed, I have heard the control room
Id itself. eg (Merrimac Control, Hampton Control, Downtown, Midtown)
From where I monitor from (Downtown Newport News) I pick up
MMMBT the strongest, HRBT almost as strong, and then the downtown & midtown about the same (weak, scratchy)
I have been told that the James river bridge is also on here, but I have not heard that myself during any of my monitoring of the 453.850 frequency. I do know that they maintain a guard on several marine frequencies and have heard them communicating with ships that they were about to lift the bridge for. Can anyone confirm or deny if they actually use 453.850 during the course of their operations?
Also, rumors that the Jamestown Ferry uses 453.850 to communicate with someone/something. I already know of them using marine channel 11 for water operations. Can anyone confirm or deny if they actually use 453.850 during the course of their operations? Thanks.
Also, if either the bridge or ferry use 453.85, what PL tones do they use?
