Using Inverted & squelch @ 1. Conventional systems avoided.
Night & day difference. Hearing sites that scanner should not hear. Not 100% decode.

Why was inverted option removed if it works??

Who has a copy of 1.07.02 with inverted?

Inverted was never removed. Original was removed.

Did some testing with the 3 settings Original, Normal and Invert using direct entry on frequencies and control channels for problem systems as well as good systems in my area. I am very happy with the SDS100 performance vs other radios.

A quick summary for those not wanting to read: It seems like it would be great to have some version of the 3 settings.

700-800mhz seemed to perform the best with Original
460mhz Normal
422mhz Original
152mhz Original/Invert about the same.

Great detailed post. At this point, judging from so many different results posted here, it looks like the best settings are definitely personal and on a case by case, location by location scenario as to which works best. I'm one of the lucky ones that the default/Normal setting worked amazingly to improve on everything I monitor. However, I DO support bringing back the Original/No Filter setting as an option.

Hearing a low level simulcast site - inside over 40 miles away using Invert setting. Several mountain ranges between me & the system.
PSR800 could never pickup that system.
Squelch set 0 or 1 =No scanning conventional with squelch that low. Trunked no issues with squelch set 0 or 1.

The 700/800 SDS100 sensitivity is very close to Motorola APX. No need for Unication with SDS this sensitive. Time for 2nd SDS actually.
Audio wise using x3 volume SDS sounds great!

Wonder if this new firmware update is going to be the same file for the SDS-200. One firmware file for both radios???

Have you tried going to the “sites” that are giving you trouble with the Global filter set at “Normal” and changing the “Site” filter to Original (or Inverted)? This should give you better overall performance; at least it seems to work for me.

Also, this can be used on conventional channels by going to the “Department” level and changing the Filter to Original (or Inverted) there only.

Thank you for the suggestion.

That’s exactly what I ended up doing prior to my previous post. Pinellas site 4 and Hillsborough P25 has their site filters changed to original and everything else is running on the global filter set to normal.

(1) After I emptied the TF card and recreated new user data, my SDS100 returned to normal, after a simple test, I still like the HPF “Global original” settings, the signal strength is the best; (2) In addition, I hope that the next version firmware, can increase the user's long time recording function (No Limit recording time, A new recording file is not created until the recording file is 2GB), sometimes a feature that is important for channels to listen to recordings.

I am hoping someone here on the forum can answer this question.

MENU --> SETTINGS --> GLOBAL AUTO FILTER

Normal (always use HPF)
Invert (always use inverted HPF)
Auto (try HPF then if no signal detected to open squelch, try inverted HPF)

Ok, I set it to invert thinking that all my favorites sites would be on invert, but looking at below you can change every site to invert. Doing a lot of testing invert was the best choice for me.

MENU --> MANAGE FAVORITES --> REVIEW/EDIT SYSTEM --> EDIT SITE --> SET FILTER (Setting menu for trunked systems)

Global (use the setting from GLOBAL AUTO FILTER)
Normal
Invert
Auto

Does global make it default for all my favorite trucked systems because I choose invert in the settings menu. I am thinking it does, but I just would like some clearifactin please.

So you set your global filter in settings to invert. Now you're going into individual trunked systems and setting the site filter to global. Each site on each individual system that you do that on will be then the same as you picked initially in settings as global filter choice, in your case is inverted. What you're assuming is correct.

In my case I have several systems and a good number of conventional repeater channels and even Simplex VHF channels. Some Requiring normal, inverted, or no filter at all. I found the default setting for Global on Normal to work for me with systems left on global with a few systems programmed to invert. There have been some individual channels I use no filter at all.

Hope this helps.

That's what I thought, but wanted to make sure I was correct. I am very happy with this new filter, because I can monitor sites with the invert setting that I never could before. Thank You

Just to further clarify. If you set your Global to invert the default for each system site filter is already global so you don't even have to go in and pick global it's already set at Global on each site. You would only have to change back to Global if you had changed it before so you are on the right track and your assumptions are correct.

This is an excellent update and has improved the radio tremendously for me as it was not working on my individual Hometown system before. Now I find that invert does the trick.

Absolutely, that was mentioned earlier in this thread. It's difficult relying on memory.

Could someone shed some light on what this "Original" setting is? As opposed to the other settings in Sentinel? :unsure:
Why is it not in Sentinel? :confused:
Does it mean the filter is not even utilized? And that prior to this FW it was not even used? But the filter was there??

Ugh, my head is spinning..

It is an SDS unit (Software Defined System) ... that means filters can be created via software code, which means once an enhancing filter is software created, tested, and found to be of good quality and performance that software code is then added to the firmware update code to be in the next firmware update as part of the SDS software code loaded into the EEPROM storing the firmware for the SDS unit. Thus, whenever you turn on the unit that code is loaded into the unit and is available for use. You can create all kinds of filters, modifications, and enhancements to the system as long as you dont exceed the hardware design capabilities of the processor and chips in the SDS Unit.

So the hardware is fixed and has limitations, however using SDS technology other features and enhancements are able to be designed by the manufacturer and provided as a firmware update to store in the Erasable EPROM to give users more features and performance up to the point where the hardware cannot do anymore, and that's when you have to buy a new unit for expansion and new systems technology.

To answer the question of what the original option is, in the first few hours of release it was an option that was available in addition to normal invert Auto. It basically was a choice that if normal and invert worsened or weakened a system or Channel you could pick original bypassing the new filters and reverting back to the original set up in the radio on that particular system or Channel.

It is a critical option that we hope will be restored. There are many factors affecting the radio including RF environment different systems and other things that could make normal and invert not help. I have the original version and option and do use it on several objects where normal and invert weaken or compromise performance.

That option of original was removed with another update a few hours after initial release and a large chorus of users have been asking to have it restored.

Hope this helps.

For me the local regional p25 system works best on original -45dbm, normal hovers around -80dbm and missing lots of traffic.

KCPL DmrT3 works really well with inverted.

Wow! I can understand why Uniden has been a little slow to turn over software tweaks to users.

Doing so gives many of us the ability to mess up our radio settings in an almost infinite number of ways--especially in light of the variables each of us have to deal with locally. One size definitely doesn't fit all.

My SDS100 is performing beautifully on the Harris P25 Phase 1/2 UHF simulcast system I listen to most, and I don't want to lose that. If I'm following this discussion reasonably well, I believe my best course of action will be to wait for Uniden to reissue the update with the "original" option restored.

I'd like the SDS100's analog performance to be on par with my trusty old BCD396XT, but I'm going to hold off on experimenting with rf filter settings until the firmware version comes back that lets me keep the SDS100's current ("original"?) settings for my simulcast system. As I understand it, the current firmware without the "original" option inserts a new, adjustable filter that may or may not improve/degrade your reception.

There's been a lot of valuable information shared in this thread, but if I'm misinterpreting any of this, please feel free to correct me.

Thanks!
