Roberts Oxygen has been mentioned more than once on KYW 1060.
Fire 1 and 2 are in use for ops, as well as FG 11 and maybe other figregrounds. Fire 4 is being used by the RIT assignment. Delco Command channel is being used to coordinate police resources for evac and traffic and whatever else they're doing. Related comms also heard on Sector 4 and 5.
Also, Delco's digital repeater on 501.225/NAC 293 is in use carrying fire traffic from Fire 1 and 2. Often has a constant carrier even when there are no transmissions on the fire channels. Not sure of the purpose for this. There's a PSP helo up for recon assistance...don't know if the patch is for the benefit of the helo. Anyone know?
Montco's fire task force is working on Montco Event 10 talkgroup and requested a SECOM patch be established to Delco Fire 8, the channel they were assigned for use to cover runs in Delco.
