When comparing my TRX-2 and BCD536 the TRX decodes DMR with much better performance. Uniden have some problems to decode DMR without issues but Whistler have managed to get their DMR decoder bullet proof. But if you have a big DMR system using many channels and many users then the Uniden might anyhow be prefered due to its control channel trunk tracking.
By purchasing fw unsupported and unfinished SDS series scanners, we will continue to support Uniden with our money. 
Unfortunately, for those of us in simulcast areas, we have only a few options. For me, the SDS series are the only devices that meet my requirements.
I would expect from the new product manager some result of his work in the form of a new fw for SDS scanners.
I do not expect his active communication here on RR.
So far, it has completely failed for me.
Uniden has abandoned Siren, and pretty much all of the x36 line. It is designed on old technology that has been replaced with SDR technology. When they realized how widespread the LSM issues were, they pretty much gave up. They used it as the test bed for provoice, DMR and NXDN upgrades, but once the realization that SDR was the only way to fix the big problem, they abandoned it like a prom night dumster baby.
If Uniden had truly abandoned its scanner lineup, it wouldn't still be making them, or updating Sentinel weekly.
Then please tell me where are the automatically downloaded updates? Where are the full Siren capabilities they promised? They have to update Sentinel for the HP1 & 2 and the SDS radios-it is purely coincidental that the software has the capability to update the x36. If something changed tomorrow that required a re-write of the software to write either the other HPs or the SDS I highly doubt they would include the x36 in the re-write if it was going to cost them another penny.
That makes no sense. It's been a lot longer since either of the HomePatrol models were updated than the x36 models.
Your post doesn't make much sense. There are two versions of Sentinel software: the original HomePatrol version (orange shield) for the HP-1 and HP-2, and the second BCDx36HP version (green shield) written for the x36 series, which was later adapted for the SDS series. Both versions receive weekly database updates from an RRDB pull, which happens late Sunday and is normally ready for updating on Monday morning.
And you are being purposefully obteuse. When was it last updated before the introduction of the SDS? The only reason it is updated is because of the SDS. If there was an issue with the SDS, that required a rewrite that made Sentinel incompatible with the x36 line, you would see the last compatible version available for the x36 and a new version for the SDS available. They will not put another penny into the development of anything x36 related. The updated Sentinel being x36 compatible is convenience and coincidence, not planning.

The fact is that this radio was never developed to it's fullest potential, and Uniden didn't admit that until they had strung many purchasers along to the point that they were out of their return window. I personally believe it was intentional on Uniden's part and that they knew they had a lemon but didn't want to have to absorb the refunds if they had let it out of the bag before hand. Even Paul started to ignore the hard questions about when promised features that Uniden kept kicking the can down the road on would be provided.
