Could someone tell me what system St Loius City fire operates on. The P25 or conventional analog? trying to help someone monitor that area. Thanks in advance.

I hate to throw a wrench into that, but just about every radio since about 1983, trunked or conventional, VHF or 800, and even Low Band has a computer that controls it. If it isn't crystalled or doesn't have channel elements, it's computer driven.Hope it works for them with all of the reception problems that digital radios can cause as it is still a computer that controls the system.
Rumor has it they will be switching over to the P25 system next month. They have indeed been testing their radios and checking buildings were repeaters have been installed. I also understand that their fire stations dispatch audible is not ready for digital signals so i assume they will still transmit on both analog and digital for a while. Remenber the county is still on analog and will not be on P25 for over a year and a half at earliest. I understand that county fire trucks that do mutual aide will have a digital radio in their truck to communicate with the city. Hope it works for them with all of the reception problems that digital radios can cause as it is still a computer that controls the system.
I'm the guy running the St. Louis Police and Fire scanner feed and it appears the fire department feed has moved away from the conventional 154.1300 frequency. I was getting it up until the weekend, but it was very distorted, primarily because of my scanner location and RF interference. I have been hearing radio tests on the the P25 system (SL Fire 1, 10205, IIRC), but no dispatches as of yet. They must be transmitting somewhere, but I can't find it. Does's anyone know what frequency or ID they are using now?
I have several fire department IDs programmed in but none of them have gone live.
I was still hearing them fine on 154.130 and the 460.175 simulcast through last evening (Sunday) around 9 PM.
I'm off work today so I'll monitor the old vhf stuff again today as well as the old analog 800 and P25 systems. I keep expecting the old 800 analog system to go dead but there is still traffic on it although fire was never on the analog 800 system to my knowledge.
I will say I've not heard a peep yet today though.
I take that back, they just dispatched on 154.130 and it sounded normal with normal signal levels out here in Chesterfield.
edit: Perhaps the RF Interference you mention is wiping out your reception of city fire VHF. What kind of radio are you using?
You may be experiencing desense from other local high power transmitters.
I just heard them again and the signal sounds very normal here.
What Mod/Squelch mode are you using (if any) for 154.1300 or the simulcast frequency - 460.175?
