Ever since getting into radio, I have been curious about what systems FCPS uses. Specifically, I always hear radio chatter on my school bus, and have been interested on what they are saying. I had touched on this a tiny bit last year, but now I'm set on actually getting it to work. Please keep in mind that I am VERY new to this. I have never worked with digital radio. Anyways, after doing some research, I decided that I would be able to use my raspberry pi 4 and an RTL-SDR Blog V4 in order to listen in, beacuse it had everything I needed. When I got it, I made the mistake of asking ChatGPT for instructions on what program to use, and then asking for instillation instructions. Eight hours later, over two days, I looked for a YouTube video and did the instillation start to finish in five minutes.
The actual reason I'm creating this is to ask if anyone can give me some clarification. Because I don't have any experience with digital radio, I don't know what I'm looking at. Now that I have My Pi-4 working with SDRTrunk (and I have confirmed that I can receive NOAA weather, though I cant hear it even though I typed in the frequency, I can see it coming through on the graphs), I've been going through radio reference, trying to find info from actual people. The problem is that because FCPS is so broad and information ranges from now the early 2000's, I'm not sure exactly what is right. I found these links:

Fairfax County, Virginia (VA) Scanner Frequencies and Radio Frequency Reference (It says school buses in general in the last entry of the first block)
The only other information I have personally is that I think I remember hearing "Area 1" on the radio, and by looking at it while getting in, it LOOKS like a Mototrbo XPR 5000e Series. (I just looked at the radio and then compared it to images I saw when searching "Motorola bus radio" on Google)
Can anyone give me clarification on what I need to do to listen to the bus frequencies?
