Welcome to RR.com!
Thanks for your service as a volunteer FF.
We used to have a dedicated Raleigh/Wake Fire Audio Feed but
it was discontinued. I hope someone here in Wake County can pick
up the needed feed and offer it. Yes, the PD/FD/EMS feed is great but I
also agree that just a Raleigh/Wake FD Feed is needed again.
A list of all provided NC Audio feeds can be found at:
North Carolina Live Police, Fire, and EMS Scanners on RadioReference.com
Happy Monitoring and Happy Holidays!
