So yesterday I upgraded my 436 in order to hear a Provoice EDACS system in my region. I am pretty happy with how it sounds. The audio quality is satisfactory and the reception is ok. My only issue is that like with Phase 2 P25, my 436 frequently fails to display unit IDs on the Provoice transmissions. Even if I have my 436 locked on the EDACS system this happens. It seems to do a little better if you hold on a channel, but even then, no guarantees. I have even turned the record feature off with no improvement. Any other ideas? And for the record, I do have the setting on to display radio IDs on all systems.

Hello,

Conventional Provoice uses a different sync value than trunked Provoice. Provoice decoding maybe limited to EDACS trunk systems.

Ok...but I have no problem decoding trunked or edacs channels in conventional provoice with my dsd + setup. I figured $50 would include provoice decoding in search mode/conventional like P25.

I'm taking a complete stab in the dark here, but in terms of P25 systems (and all trunk systems, AFAIK), there is a message called a "continuation" or "late entry" message which basically says "radio 123 is still talking on talkgroup 4567 on channel 789". This is for radios who, for whatever reason, didn't get the original channel grant message, because they either weren't listening to the control channel or talkgroup at the time, or were powered off when the grant first came up, or something like that. On some systems (IIRC, Motorola analog is the primary example), the radio ID isn't contained in the continuation message. It just says, "yup, conversation still going on on tg 4567 on channel 789", without telling the world which radio was the last to get a channel grant. In such a situation, radios receiving the continuation message wouldn't get the radio ID, they'd just get the TG ID. This is why if you're parked on a TG, you'd get the radio ID more often, because you'd see the initial channel grants more frequently since you're not off on another TG listening to something else.

Now maybe ProVoice voice frames don't include the radio ID, or maybe continuation messages in EDACS (or EDACS PV) don't have the radio ID. I don't know, as I'm not an EDACS expert. Or maybe Uniden's implementation of reading the continuation messages doesn't 'see' the radio ID.

Make sense. It acts almost identical to how it does on phase 2. Also in another thread (or maybe this one) someone asked why Provoice isn't decoded in frequency search mode. It should be noted that phase 2 also cannot be decoded in channel search. It is interesting that once when I pprogrammed all voice channels in a phase 2 system, morere radio IDs appeared than when just the control channel was programmed. I wonder if there's a correlation.

On the ProVoice < UnidenMan4 < TWiki is says Homepatrol

Does this mean the HP1 or HP2? On my Uniden website when i register my HP1 it gives me a 50$ Purchase Upgrade Key option. I have the advance software already in it so im just curious if this was for Provoice or not

It shows...

Uniden caps another first in scanner technology by being the first and only scanner manufacturer to add the ability to scan and monitor EDACS ProVoice trunked radio systems in their flagship BCD436HP and BCD536HP scanners.

...so I'm betting no...but I could be wrong.

You may be seeing the registration prompt for the Extreme Upgrade. I see that prompt too on one of my HomePatrols even though I have already registered the Extreme. The only radios announced for the ProVoice upgrade so far are the x36HP radios.

Ok it must be in the confusion wording then here


This $50 upgrade is available to all owners of Uniden's BCD436HP and BCD536HP HomePatrol Professional Series scanners by registering their product at myUniden - Customer Product Registration and Support Area. Uniden Scanners are available at Uniden.com and other resellers nationwide.

Can be confusing... The HP at the end the x36 series model stands for Home Patrol... So the way it's worded you would think the HomePatrol 1 and 2 is included too... Although the HP1 and 2 is not categorized as Professional Series...

Can someone tell me if ProVoice would do me any good here in Clinton, Iowa? I've been checking the database and it doesn't say if the Racom system uses it or not in my area.

Did you post in the Iowa forum... They can probably give you more info on that...

Any talkgroups with a D (digital) on this system are using ProVoice (except the few which say "Aegis" in their description). There seem to be a small handful of PRV talkgroups, but only you would know if they're geographically near you (i.e. Fayette County, Polk City PD, etc). Keep in mind it's also possible that there are talkgroups that aren't even in the DB because nobody has ever scanned them before - you might only discover them if you get the PRV feature and do ID Search on the system.

My question is this ; if you install the provoice upgrade and then
do a id search on a edacs system will it decode them and show id.

In the above no provoice channels are programed into system.

The system may have them but are not in the database.

Hello,

On my local system, that is all ProVoice, the scanner had no problems finding new talkgroups during an ID Search.
