I was not aware of any online streams from Delcom, I will have to check into it with the two dispatchers there from my fire station. You might want to wander on over to
www.firerescuenews.com and inquire there (its Delco based).
As far as the new PC it may be awhile, I'm working 12hrs/7days right now until 8/20 then off till after Labor Day for vacation (I'll really need vaca by then...). Till then I'm relying on the wife's lappy and my work comp. If I get something going before then (or before someone else here posts a file) I would be happy to post my file, heck I'll even throw one together just for Philly Fire and Police.
The Philly Police bank that I have now contains every TG from the Database here (programmed by hand in about an hour one quiet night here at work) and when I select that bank you can forget about hearing anything but the Police. The transmissions are constant, it's unlike anything else I've monitored.
