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.
