SDS100 Prerelease Discussion

[CanesFan95]

Its a quirk with all Uniden DMR scanners, Upman has confirmed they won't change it and won't even add resume as an option, their heads are buried deep in the sand.

It makes autonomous operation near impossible it will hang on custom search, scan with search or if you get a DMR signal on a conventional channel.

If, like me, you want this feature you'll have to stick with Whistler or AOR.

It seems awkward to have to program conventional DMR frequencies as a trunking system to really make it work. Tier II isn't considered trunked, is it? I would rather it know to just keep scanning if it's not a voice call and let me program in the slot and TG ID with conventional DMR frequencies. Conventional DMR doesn't have system IDs, does it? To see the slot, color code, & TG ID, you could just hold on the frequency and look on the display. But if you already know the slot, color code, & TG ID, then it would be nice to be able to program that in and not have it hang for non-voice data.

That's less than the nominal power draw on the 436--500mA.

That "awkwardness" gives you capabilities you cannot have when programming the frequency as conventional. You can't apply different service types to each talkgroup when multiple talkgroups are used on a single frequency, apply separate service areas per talkgroup, nor can you have separate labels for each talkgroup, if you program the frequency conventional.

Tier II isn't considered trunked, is it?

If it's continuously beaconing control channel data, then yes, it's trunked. If not, then programming the frequency as conventional isn't going to indefinitely hang the scanner.

What? There is a resume "option" - twist the knob, one click in either direction.

Best we could do while mobile. This is not my home system and all channels were default to 2 second delay and site was holding on Columbus City while driving through the Short North clear past OSU and the Old North almost into Worthington area.

Good decode right in the center of town, and horizontal as well.

Be careful though. At 14:50 you were pressing buttons and ran a red light.

We all appreciate what you are doing but don't get yourself killed while doing it

Im not sure I understand how the dmr is supposed to work ,.. being familiar with my 396T,..I would hope ,..or expect that , it would be much the same as any other trunked system , with the ability to select or deselect different talkgroups via hotkeys & or ,.be used in ID search mode ,where new Id's can be found while still ignoring locked out id's ,..If you cannot properly track certain talkgroups & lockout others & search for new ones ,..especially on a busy system ,..then I kind of dont see the point

 

[UPMan]

DMR works as you describe (assuming you've programmed it properly).

 

[jonwienke]

How exactly will that happen if the scanner automatically skips over the frequency the way woodpecker wants? You won't know what frequency or channel to hold on, because the scanner would always skip past it without stopping as if there was no traffic.

If you program the DMR frequencies as One Frequency Trunked or MotoTRBO Trunked, you have pretty much the exact same functionality with a DMR system as you do with a P25 system as far as tracking conversations on a talkgroup even if the frequency changes, and filtering traffic by talkgroup using service types, location control, avoids/lockouts, and quick keys. The only way you lose that capability is if you program DMR frequencies that carry multiple talkgroups as conventional instead of trunked. Which is why woodpecker's complaints are nonsensical.

My main purpose of going Live was to get as many eyes & ears as I could for feedback.

I was able to report 3 additional bugs to UJE and will be waiting for updated firmware. I may then, go Live again with some suggestions and comparisons from that feedback.

Keep your eyes peeled here or on my YouTube Channel at: https://www.youtube.com/user/jasonhouk

Thank you for all the videos. Really enjoy!

Or even several clicks - the scanner isn't picky.

There's been some posts deleted about this, so we don't have all the info here.

Ok so then it would sound like its implemented in a way that works like one would expect ,..I dont fully understand How dmr works ,with the time slots complicating things , but if it essentially is programmed the same way p25 trunk system & works the same , I have one of those tyt MD380s Its ok for a small dmr system with little traffic ,..but we have some bigger systems here as as well that are busy & tough to follow your target with the md380 method Oh on an unrelated note ,.. What do people recommend to clean & prolong the life of radios that have a plastic case ? I have been using pure silicone oil for a long time ,..I believe it restores the oils into the plastic & assists in keeping it from becoming brittle , I could be wrong though ..

DMR is based on a/D and D/A conversion. Since this takes some time to convert in each side, the audio is packed into a stream and transmitted at twice the speed of the original speech. Due to this, the data can be split between two transmitters in the time domain as follows:

|USER1 data|-||USER2 data|-|USER1 data|-||USER2 data|-|USER1 data|-||USER2 data|-|USER1 data|-||USER2 data|-|USER1 data|-||USER2 data|

User 1 in the above graphic is using Slot 1 and user 2 is using slot 2. Each one gets the airtime to send their voice data to the receiver. The receiver monitoring slot 1 ignores the slot 2 data and vice versa.

That's somewhat of a simplification, but did it explain any part of it?

Indoors 20+ miles away from the nearest tower one county away with stock antenna. The SDS is still decoding the COIRS system.

I'm ready to lay down my $700 for the SDS100! I can't wait for its release!

 

[Johnegunz]

$699 for a handheld that requires a paid upgrade for several types such as NXDN. Too pricey for me.

Wow. That is pricey.

 

[racin06]

Uniden will sell a boat load of SD100's at $700. The SDS100 is a huge performance boost over the BCD436 and that is what commands the $700 price tag. It's the free market working as it should.

Amazon will have a much better sale price then most other places. And less then $200 for the 3 add ons is well worth it.

Just a reminder (this has been covered over and over in this thread), the actual price will almost certainly be a good bit below MSRP, as it has been for past models.

You're assuming Amazon will sell it... see the "536 Safety Issue" thread.

(I'm only being half-facetious. Amazon's sales policies are getting sketchy these days with a number of companies.)
