DoITT UHF P25

[GTR8000]

So I was not familiar with the SDR dongle but have been doing a little research. Would there be special software to download to be able to listen to a trunked P25 system? I watched some videos on YouTube. One guy said you need 2 dongles and download 4 different software programs. Do you have any more info that would make it easier? Also all I have to use is Chromebook.

So I'm planning on purchasing a SDR dongle. I could get two but in what situation would I need two instead of one?

If the only thing you have is the Chromebook, you're probably out of luck when it comes to decoding a P25 trunked system. I'm not aware of any P25 trunking software that will run on Chrome OS natively. The Chromebook is a pretty weak device compared to a modern PC or laptop, and so even if you could run a Windows or Linux emulator, you're probably not going to have much horsepower left to run the decoding software.

You're probably better off looking for a decent used laptop with enough horsepower to use with SDRTrunk or DSD+ Fast Lane, both of which can decode P25 TDMA. OP25 requires Linux, not sure you really want to go down that rabbit hole.

I work for an agency that utilizes this system and we all agree on our job it's horrendous. Maybe not from a monitoring standpoint(not that i have been home much in the last year to monitor stuff) but actually using the Motorola APX 4000's to transmit and receive I have heard a conversation on three different radios - a base, the reply on one handheld and the reply to that on another handheld in another room.
There were no problems when we were on the stand-alone DOITT UHF system. We also all sounded like human beings.

can DoITT UHF P25 system be programmed into the APX ?? what is needed to be programmed into it ?

A system key from the system admin perhaps.

that's not a problem !!!! is the configuration !!!! some of the stuff I got right , but UHF Phase 2 is a dead end for me , can't hear anything on NYCICN UHF !!!

You clearly don't know what you're doing, so stop now before you cause harmful interference with the system.

 

[ASTRORADIOS168]

because this system doesn't exist anymore LOL

there's a way to program it non- affiliate

Yes, I'm fully aware of that, having programmed countless APX subscribers over the years. The point is that you obviously don't know what you're doing, otherwise you wouldn't be asking how to do it. Stop now before you wind up with a very expensive paperweight.

paperweight, i have ways to prevent that even if it gets stunned

 

[GTR8000]

Cool. Good luck figuring it out.

i'm not just any civilian LOL

 

[GTR8000]

Yeah, okay Allen, whatever you say. Time to move on.

please I could confirm this is not a 800mhz , cos I got the 800mhz phase system correctly

 

[APX8000]

What Unit ID do you use ? Asking for a friend....

57005.

Some people probably won't get this, sorry.
