Hey,
I've had a feed up and running for a while now which covers my county's police, fire, EMS, and SO. It is P25, and I've run into an issue in trying to provide "complete" coverage. When EMS/FD are paged out, a pre-alert goes out over the Law Dispatch TG, then the dispatcher says something like "Dispatch to Fire/EMS Station #, medical emergency, 1234 Main St, standby for page". Then the call is actually paged out over the VHF system. When I used to live in another town that did it that way, it was no problem, because all I did was connect an analog scanner to the right channel and locked it to the pager frequency. However this city does things a little different and with that setup it's unintelligible during EMS pageouts.
For some reason the EMS pageouts (including tones) are simulcast over the P25 Fire/EMS Dispatch TG, while the FD pageouts are not. I actually didn't realize this for a while. I tried to set up the stereo feed again, but - due to processing or whatever - when EMS is paged, it is delayed on the P25 scanner about 3/4 of a second behind the VHF scanner. Since FD pages only come through VHF it fixes the problem of missing those, but EMS pages come through the stream as an "echo" and it's impossible to understand unless you shift the balance.. The delay seems to be pretty consistent, so is there a way to delay one channel in order to sync them up? I'm using RadioFeed.
