SDS100/SDS200: How can I go back to the previous firmware

[Ubbe]

You are assuming that the RSSI indicator / measurement is working correctly.

Yes, the RSSI value comes directly from the receiver chip before any signal processing have been done. If it doesn't show correct values then the receiver are getting compromised from other RF sources that mess up the receiver. If the attenuator reduce the signal 20dB then the receiver are working within its limitations. If the signal drops more than 20dB then the receiver was overloaded. It indicates that the gain probably have been set higher in the latest firmware and it more often than before will go into overload mode that results in both distorted reception and squelch issues. As soon as the squelch close all reception and digital decode handling stops.

If the firmware is working correctly.

Here's the Sub Firmware for 1.21.00 on the SDS100.

Weird. I downloaded your posted .zip file, extracted it, and all that is in it is a very short .mp4 video file of the scanner. No firmware files.

Not sure what you did, but you can't "open it", but have to Copy into the scanners firmware folder either when the scanner is plugged in, or use another SD card and do it directly from the computer. I wouldn't do that unless you have 1.21.00 loaded though and if the current firmware isn't working properly.

Is the scanner's Firmware folder stored on the pc?

No..it's in the scanners SD card.

I see thanks, just trying to learn all I can might come in handy.

Is the scanner's Firmware folder stored on the pc?

Yes, it is backed up in C:/ ProgramData/Uniden/ BCDx36HP_Sentinel/Updater
.bin file
.firm file
Once the firmware update is completed, the firmware files are erased from your SD card, so you won't find it on there. At least that is what occurred on mine.

 

[crippledchicken]

Thanks I'll check that out!

Can you send me previous firmware files and how to do it ? not good with computers , too old I guess, my E_Mail is brandy9@comcast.net Thank You

What a disaster. I blame all these beta testers. I had the same issues with Unication firmware releases. The day they were released I installed them only to find numerous obvious bugs that should have been easily caught.

I'm rolling my 200 back tomorrow. RSSI jumping all over, on and off CC. I ran it through all different settings. Firmware issues.

how you do it ?

Which FW are you on 1.23.01 or the latest 1.23.03 Which causes the RSSI and CC issues ? I understood that only the non P25 systems were the recipient of these issues .

1.23.03

The 1.23.01 seem better than the 1.23.03 . On the 1.23.03 most of the time the scanner just keeps scanning. 4 to 5 antenna bars but nothing heard most of the time.

My SDS100,200 is having a hard time with Delaware smart zone system now with the new update. I’m getting a lot more digital gargle now.

Im getting plenty of Smart zone garble in Milton and I haven't even upgraded the firmware. Still running 123.01
Any luck switching back?

Many of those issues were addressed in updated firmware versions. The current version is 1.23.05/1.03.05 via Sentinel.

The latest release version corrected the SmartZone issues that started with 1.23.01. I drive through Southern Delaware / Sussex County several times a week and SDS100 has returned to normal after applying FW 1.23.05 / 1.03.05 sub.
