VX-P829 P25

[K0WOI]

Attempting to program VHF P25 non-encrypted non-simulcast non-trunked channel into my VX-P829 using Talon software. Under the P25 RX settings the mode is set to "D", NAC is set properly; SQL set to "N", MONI set to "Disable". In the P25 Function, set for a TGID of "1". Radio will not pass audio, though I can see that a signal is being received on the screen and because the green light flashes. And I can receive the traffic just fine on my Unication G5. What am I not setting correctly? Is it perhaps the P25 RX "MONI" mode needs set to either "Code SQL" or "Noise SQL" instead of being disabled?

Also, can you use the NAC wildcard (3966) and TGID (65535) in these radios if you don't know the correct NAC/TGID? I my case, I do have the correct NAC and TGID's for the channel I'm trying to monitor, however.

Thank you.

So, I've not dealt with Talon. I don't remember TG3966, but yes TG65535 will pass all TGs just like NAC F7E will for just P25.
I'd try 65535 first and then F7E if that doesn't work, just to confirm it can RX with how you're setup.

Correction - I was thinking in Motorola hex. Yes, NAC 3966 is the Vertex decimal of F7E.

I'm having this same problem the RX light comes on but no audio heard. Did you find a fix for this?

Yes - I messed up and had the "ID Display Format" set to DEC instead of HEX in the Talon software. Once I changed that and re-entered the NAC and TGID's all was good.

I'm trying to put in this One freq P25 Adams CO IL EMS. I had the ID Display format set to HEX and The correct freq, Mode D, NAC 294, TGID 0001 I can hear the dispatch at times can't hear the EMS Ambulance but I know they are talking the light is flashing and I can hear they good on my scanner that is how I got the NAC and TGID. Anything else i should do before I give up on this?

My personal experience using these, within coverage of whatever system you’re listening to the radio will sing great. Start getting to the fringe of coverage BER goes crazy with these. I have a P824-G7-5 and once a transmission drops it’s very in and out and will miss portions of transmissions

what is weird dispatch works ok but mobiles don't and I know they are talking the green light flickers and I hear them on a scanner but can't hear the mobiles at all on this VX-P829. Don't know if I have something set wrong or what

 

[carlos7801]

Is what your monitoring maybe partial E? Or Simulcast? Because that’s the only two factors that would lead to the radio not unmuting upon given NAC. With AES it’ll garble with the squelch open, and ADP isn’t recognized by the radio so it’ll light up but remain silent until a fully clear transmission comes over.

It does look like its Simulcast to Starcom. Is that why I'm not receiving the mobile units? Because I know it works fine on my Uniden BCD996P2 scanner

Correct. The VX-p family doesn’t decode simulcast systems well or at all due to the Receiver not being able to properly time multiple incoming sources on the frequency if I’m not mistaken. Single site, and I mean literally one standalone repeater it works very well. Since my radio isn’t flashed for AES, it just sits collecting dust.

Yeah i was trying to listen to the local EMS which is on a single freq but also on Starcom which they were linked when they was just digital. I could hear the dispatch good most of the time but not the Ambulances. The Quincy PD, Fire and Adams Co sheriff is suppose to do P25 also but the are not linked to Starcom for now. If they do I guess I got a analog /P25 2 meter hand held.
