SDS200 Firmware Update Change Log
All firmware updates are done using Sentinel. Select Update --> Update Firmware
Before applying updates, you should back up your programming. Always use the latest version of Sentinel to update.
1.03.06 Sub (7/11/2024)
Increased audio level in Waterfall AM mode. Nothing else has been changed.
- Fixed an issue where the P25 Phase 2 NAC was not displayed correctly on voice channels.
1.23.05 Main (2/2/2024)
This firmware applies the following bug fix:
- Fixed a bug in Waterfall mode where the IF polarity was switched at a specific frequency and the carrier was displayed on the opposite side.
1.03.05 Sub (1/19/2024)
This firmware applies fixes for the following issues:
- Fixed the reception issue on Motorola Type II sites.
- Fixed an issue where there were spots where no received audio was heard when moving the marker in waterfall mode.
1.23.03 Main (12/28/23)
This firmware applies the following enhancements and bug fixes:
- Fixed that disabled RECORDING when entering waterfall mode.
- Fixed an issue where the Signal Bar and RSSI would not be displayed when a weak signal was received.
1.03.02 Sub / 1.23.01 Main(12/21/23)
This firmware applies the following enhancements and bug fixes:
- Support Waterfall
- (Latest version of Sentinel (2.05.03) required to use these features).
- Improved digital reception performance. The improvement effect varies depending on the receiving area.
- Fixed the problem of P25 Phase2 Unit ID not being detected.
- Improved P25 Phase2 signal detection rate.
- Improved P25, DMR, NXDN OFT signal detection rate.
- Updated Filter for P25 Phase1, DMR, and NXDN.
- Increased the speed of digital scanning.
- Improved accuracy of the reading for RSSI and the number of signal bars. The current readings are more accurate than previously were across all bands. The firmware update that implements the Waterfall Feature did not affect the sensitivity of the radio. In some cases, the new RSSI and signal bar readings may be very different than they used to be, creating the erroneous impression that the scanner is not performing as well as it did previously.

1.21.00 Main (6/29/2022)
This firmware applies the following enhancements and bug fixes:
- Added 2.5 kHz and 3.125 kHz steps to the Custom Search and Discovery mode.
- Housekeeping update to accommodate revised hardware.
- (latest version of Sentinel (2.03) required to use these features)
1.10.00 Main (4/15/2019)
This firmware applies the following enhancements and bug fixes:
- Fixed the issue of false TGID displaying during site hold.
- Modified the valid condition of EDACS system ID.
- Improved DMR OFT reception.
- Improved NXDN48 (OFT) reception.
- Slightly improved the clarity of analog and digital voice
1.09.02 Main (4/5/2019)
This firmware applies the following enhancements and bug fixes:
- Fixed the issue of stopping scan during priority scan.
- Fixed the issue the open squelch backlight does not turn off till hold time expires
- Changed housekeeping off while scanning one site and detecting its control channel (drop in reception every 2 seconds).
1.02.01 Sub / 1.08.05 Main (3/7/2019)
Be sure to also update Sentinel when applying this update.
This firmware update applies the following new settings and bug fixes:
- Added an "AMP OFF Timer" setting that determines how long the amplifier stays on after a transmission ends. If you hear hum between transmissions, change this from Infinite to one of the available settings.
- Added "Wide Normal", "Wide Invert" and "Wide Auto" filter options for FM performance improvement. When you pick this setting, the filter becomes weaker for interference on a nearby frequency. However, the linearity of the IF can be maintained even when there is strong interference within the band, and the reception may be improved in some cases.
- Added an option to display the filter setting when customizing the display.
- Improved a reception dropout issue where dropouts are often accompanied by "LINK" icon appearing at start of dropout.
- Improved crackling noise on analog.
- Improved the reports that some REC files created have no audio captured at replay.
- Added a prompt to exit certain modes.
1.02.00 Sub / 1.07.04 Main
First release firmware adds additional countermeasures to help in strong signal areas (especially for VHF/UHF). It also adds a user option to set the default RF High Pass Filter (HPF) used.
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)
Note: If
Auto is selected, conventional scan and search speed will be greatly slowed, as every frequency on which a signal is not detected on first pass will be rescanned using the inverted HPF setting.
