Hello,
I have been testing the new firmware and just wanted to create a list of bugs/anomalies that have been reported, not just by me, but by others, including forum members, Roger, Koshak, and all of the devs. I just figured it would be good to create a "master list". Many of these bugs are already known and the causes are being investigated.
Updated 7/15/26
General Radio FunctionsUnable to save settings updated by the user directly in the radio menus
Includes:
Transmit Power
GPS settings
Sounds
Per-Channel Squelch settings
Programmable Button functions (SK1/SK2 and P1/P2, but this may not be possible and is not currently supported by OpenGD77)
Basically if you change it in the radio's menus, it does not remember after navigating away from the menu.
UPDATE - User error. You must press the OK/menu button after updating settings instead of the Home/Back button. This saves themGPS functions are not yet implemented or not working
Note - Even if they were, the settings set by the user do not save, so even if GPS is enabled, the radio won't remember.
UPDATE - Was able to get working after figuring out the menu settings issue.APRS functions not yet implemented and/or working
UPDATE - Seems to be working after figuring out menu issue.- Inconsistent calibration data across different handsets causes different transmit power settings.
Note - This may be due to an inaccuracy of the calibration data in the BaoFeng firmware compared to the inconsistent performance of the hardware itself. But this can be a big issue as the average radio user will not be checking with a meter
- Potential issues with radio not detecting the movements of the channel switch knob properly when changing channels in a zone causing the channels to go backward at times
Note - In the original firmware the channel change function was slow/delayed. This could be by design due to the cheap/inaccurate physical dial on the device.
- Custom loading screen reverts to OpenDM32 screen.
When you customize the loading screen in the CPS it eventually reverts to a blue screen saying OpenDM32. Despite no programming updates.
General TX/RX Issues- Squelch issues with DMR and Analog
Includes a rhythmic "rapid pulse" or clicking sound, but doesn't appear on every channel
- Radio receives a signal from a repeater or channel, the meter at the top of the display indicates there is a transmission being received, but no audio is heard.
Note - I experienced this issue. You can fix by changing away from the channel and then changing back. But it is still an issue.
UPDATE - Improved in version OpenGD77_DM32_20260711
- Audio amplifier is active even when no transmission is received
Detail - You can hear a buzzing if you turn up the volume all the way, even when no signal is being received.
- Green receive LED flickers but no sound is heard/received. Intermittent issue.
UPDATE - Improved in version OpenGD77_DM32_20260711
[/list]
Aviation FrequenciesAviation bands 118 - 133mhz always squelched/minimal ability to hearZones containing aviation frequencies do not allow frequency scanning
UPDATE - Both seem to be fixed in version OpenGD77_DM32_20260711
[/list]
DMR-Specific Issues
- Display page refresh method causes drop-out in DMR functions/CPU cycles/transmit power
- Unusual transmit lock indication and/or transmit lock not taking place as expected after PTT is held
- Drop-off due to an issue with the 11th data frame, possibly due to a memory issue and/or an undiscovered variable
- DMR does not work as well/corrupts on low-power settings.
UPDATE - Some of these issues have been improved in version OpenGD77_DM32_20260711, but are still present to an extent
CPS/Programming/Interface Issues- Cannot read/write certain theme data to/from the radio with the CPS
Roger was able to reproduce this. Certain fonts and colors cause a COM failure.
[/list][/list]
UPDATE - Improved in CPS version E2026.07.13.01 Firmware versopm OpenGD77_DM32_20260711, but I have not tested if this specific issue is resolved
