What does a person do when they want to learn how to identify trunked systems? Right now I just want to get a little taste of it. I am not quite ready to rip apart my only receiver and install a discriminator tap, but I understand you can do a little of this with just the straight audio out.
So, I downloaded Universal Trunker. Set up my radio. And now I'm seeing systems pop up as I tune in various control channels. (It appears to be working as expected). I've synced all systems with the RR DB using the built in sync button. RRDB knew something about 5 of the systems. However, I found 7 systems for which it appears there are no RRDB entries for. They are probably business systems. Two of the seven are MPT1327 (I'm guessing those are UTA sites?). So, I probably can't listen to those (I am guessing there is some way to do it, since this software can decode it). That leaves 5 left, all of which appear to be Motorola systems.
On some systems I'm getting a 50% decode rate. On many, I'm getting 99%. I would guess that isn't too bad using just the audio out. Now that I have a list of unknown systems, what resources should I start to check out next?
I used the FCC ULS tools to identify who might own the control frequency of a system identified as 4936. The strongest signal I'm getting is for this licensed system: http://wireless2.fcc.gov/UlsApp/UlsSearch/license.jsp?licKey=209246
Where do I go next to identify all the frequencies & sites that might be involved? What format should I follow when submitting these trunked systems to the RR DB?
