SDS100 Prerelease Discussion

[marksmith]

Since any speculation about the release date is nothing but a wild *** guess, especially since FCC approval has not happened yet, are completely not credible, maybe everyone can save us from reading these garbage guesses by not posting them.

Except Upman.

Doubtful the SD card will get "hosed up" from turning on/off ingnition of a vehicle as it has an internal battery.

My HP2 is "wired" to my Jeep's electrical system. However, I never keep batteries in it. On-off cycles don't seem to corrupt the mSD card.

Turning off the replay feature will help. Otherwise the radio is constantly writing to the card. Without batteries I don't think replay or record will function.

Turning this feature off means the card is read on startup, and after that only if you are changing settings or using GPS and changing areas. Both of these two things probably are not happening if you are killing the ignition.

Looks like it’s time to start a new topic since this one has strayed as they always do.

There is a users manual available for light reading.

Wow. They put the entire users manual in their magazine? That is a blatantly useless murder of innocent trees, as the users manual has been posted here (at least a couple of times).

I’m sure I will be upgrading my 436 and probably my TRX-2 when the mobile version comes out due to heavy use of simulcast in my area. I was hoping, however, that Uniden would change their DMA style with a new release so that when you scan selected favorites lists that reuse systems, the scanner would determine this reuse and build a quick list of systems internally. My desire would be to see a programming architecture in these new models where systems are entered only once in the software/scanner and then channels can be reused across favorites lists without maintaining multiple copies of systems lists to maintain with every update. This would also avoid the common issues where the scan cycle could hit a system several times, each occurrence looking for only subsets of talkgroups and missing intended ones. With all the changes going into new hardware, I would have hoped that this would have been considered. I am seriously excited about the new model though.

Is there any videos of it scanning a lsm system for longer than 1 minute?

Great suggestion!

Not that I am doubting it's capabilities. I would just like to see it track the same LSM system (maybe held on the same talkgroup) for a few minutes.

That is not going to happen. Programming a system multiple times with different sets of talkgroups enabled in each instance is a grossly suboptimal way to program a trunked system, and you should never do that. Talkgroups in a trunked system are never scanned, what is actually scanned are the frequencies on each site. If you program a system 3 times, once for fire, once for EMS, and once for police talkgroups, you have about a 67% probability of missing any given transmission. When scanning sites of the police instance, all fire and EMS traffic is ignored. When scanning the sites of the EMS instance, all fire and police traffic is ignored, etc. The more instances of the system you program, the greater the odds of not hearing traffic. So just don't.

The correct approach is to program the system only once, and use Service Types, Location Control + GPS, and/or Department Quick Keys to filter traffic as desired. It uses less memory, scans faster, and unless there are multiple transmissions of interest happening simultaneously, missed traffic will be minimal.

I agree. I'd also like to see it in action while mobile and also monitoring multiple systems.

 

[UPMan]

No that's not the answer, that won't stop custom search hanging forever on a beaconing DMR frequency.

Also there are many channels that share analogue and DMR and without this option no way to stop a conventional channel from hanging indefinitely on a beaconing DMR system.

Many more users requested that custom search mode display SYS ID, Site ID, etc. If the channel is skipped, that cannot happen. So, either AVOID, scroll, or use negative delay.

I don’t think all the frequencies listed are scanned in a trunked system. I have read that only the control channel frequency is scanned in a trunked system and that the control channel gives the information needed to the radio to jump to the proper frequency or is that what you meant? I realize that sometimes LCNs are needed to be listed as they are part of the needed information to allow proper calculation of the next needed "jump to frequency" to follow the conversation or have I missed something?

If this can done for the DMR during custom search, can we get this feature added to the SDS100 /X36 series so we can scan for trunk system like the old CC Only? Many users have also requested this in the forums.

The listed frequencies for each site are scanned until a control channel is found. What happens after that depends on what is received from the control channel.

But under no circumstances are talkgroups scanned.

 

[RF23]

That certainly seems to make sense but that is what I thought in the past and I would numerically order my frequencies both in conventional scan mode (where it will speed up the scan rate) and with my trunked frequency listings. However, a number of people told me that the order & number of the frequencies in a trunked system would make no difference in the scan rate (perhaps they meant because it is such a small list of frequencies) and I missed understood.

I have tried putting the control channel first and the alternate channel next and then compare that to putting them last on the list of frequencies and I cannot seem to see a difference in speed. Of course with bigger trunked systems and perhaps better technique in measuring speed I would see a difference.

I have even removed all the frequencies except the control channel frequency in some large state wide trunked systems and it made no difference in scan rate.

I certainly agree with what you have said and I guess I will study on this particular topic some more.

Can you add an option to the custom search to skip if no audio, it could be on/off or even better a number of seconds.

From a road safety point of view while driving, trying to look at a scanner screen to see if its hung and faffing around trying to hit a small avoid key is no better than texting at the wheel.

Also if you want to discrete monitor with a bluetooth tx/earpiece and have the radio in a backpack it just doesn't work.

On the flip side of your point about what most users request, this wouldn't mean not displaying information, surely if you wanted to view that info you would just hit hold and view it. The TRX-1 and 2 work like this, you hit the pause key to view the info or it continues searching.

I just cannot see the logic in having the scanner hang forever, having no timeout at all makes no sense, I own a lot if digital radio equipment and nothing except Uniden has the hang forever quirk.

The Uniden logic is the reverse of all other manufacturers, with Uniden search you have to make an input to continue, with everything else its make an input to hold, can you at least give an option to reverse this logic.

This is probably the most on-point post i've seen in this thread...hit us with a several minute clip on a busy talkgroup...how about some extended Phase II audio...this is where it's going sooner for some than later. If it sounds like garbage with inconsistent volume or sounds muddy then it's a pass here.
