Is there any P25 Phase II scanner in the works anytime soon (a successor to the 396 series)? Harris County's TxWARN P25 sites have had a few Phase II TGs pop up lately; and the City of Houston is close to finishing their Phase II ASTRO system.
Nope...You're going to have to buy a new scanner if you want to listen to these new systems. Upman already stated in another thread somewhere that it would be a hardware upgrade and that's not going to happen. Apparent at Uniden they do not think in terms of upgrading current equipment, they just want to sell you new equipment. Makes sense from their point of view but not from ours. So we have to wait on Uniden and the others to see what they will do about TDMA X2 and hope the new scanners aren't $600.00 plus dollars. Merry Christmas.I have no knowledge of this, but I would think maybe a firmware update to the HP-1 could accomplish this?
It was to areas that are changeable with firmware. There are basic subsystem functions in any hardware design that are beyond mere firmware modifications. While the licensed DVSI chip/software for both IMBE (FDMA modulation) and AMBE (TDMA modulation) do contain parameters that are addressed with firmware, the basic encoding/decoding processes are different and are beyond firmware. This is actually where the people posting about the problems with 396/996XT have a legitimate question, as it would seem that some of the things they would like changed (other than TDMA) are in firmware...I seem to recall a recent upgrade to current equipment (HomePatrol-1).
The change that I keep whining about is actually a function that is on the396T. My 396T is much more pleasant to listen to than the 396XT due to the ability to set the P25 threshold level manually on a per system basis.The 396T has single digit P25 error levels and good audio while the396XT error levels are up around 50 and sounding like garbage.This is actually where the people posting about the problems with 396/996XT have a legitimate question, as it would seem that some of the things they would like changed (other than TDMA) are in firmware...
I felt the same about the PSR-800 but bought one anyway because everything where I work was not working on my other scanners. Now that I've had it a while, I love it.I hope something comes along sooner than later, because as soon as the mentioned systems start using Phase II, he's gonna have a lot of people wanting answers*. And no, I am not going to get a PSR800. I would prefer a scanner where you don't need a computer just to change a frequency.
*Mainly wrecker drivers. In the Greater Houston area, law enforcement requests wreckers over the radio.
You obviously understand it, but others seem to expect Uniden to do exactly that. What I haven't figured out is why GRE (and as a result RS) aren't held to the same "standard". Last I knew, GRE still hadn't pronounced the 800 as fully compliant with P25 Phase II - where's the hew and cry for either a firmware upgrade or a statement of compliance? Where's the demands for GRE to upgrade all of their other scanners to TDMA? (Unreasonable? I agree, but what's good for the goose....). The repeated poor mouthing of Uniden for the engineering / business decisions that all three companies are making sure gets tiresome.OldCJDCOps: I knew all that. Sky was saying Uniden never makes updates, and that was wrong, they do. Of course, they can't magically make new hardware appear in products that have been out for a couple of years.
You're missing the point, which is that the PSR-800 already contains the hardware to decode TDMA. That has been proven on live X2-TDMA systems. Uniden, by contrast, has not yet released a model that decodes any flavor of TDMA.What I haven't figured out is why GRE (and as a result RS) aren't held to the same "standard".

Just like the current Uniden models, they cannot be "upgraded" because they don't contain the proper hardware.Where's the demands for GRE to upgrade all of their other scanners to TDMA?
I never said there are no Phase II systems currently online. What I said was that when GRE addressed the issue (a few months ago), there were none online as of that point.But, as far as Uniden not covering any type of TDMA, the low number of X2's sure wouldn't justify it and as you've pointed out, there are still no Phase II production systems in the US to test against, so what's the issue to get everyone's shorts in a bunch over, aside from just railing at Uniden?
