Version 7.3Q
* Minor bug fixes
Version 7.3N
- Add audio amp mute feature:
- When the audio mute is enabled, the radio mode (FM/DMR) font is stroked.
- Add "Mute: On/Off" in quick menus.
- Use longpress '0' key for audio mute toggling.
- Some internal cleanups.
Version 7.3M
- In DMR mode, clear the LC data after an APRS beaconing to avoid handling incomplete data (wrong IDs and so on).
- Fix APRS QSY: RX and TX freqs were swapped.
Version 73.L
mostly small bug fixes for the APRS
Version 7.3K
- Add GPS baud rate detection
- Show channel distance when scan is paused
- Fix bug in channel/VFO modes when scanning with VP
- Add last talker in screen option.
- In DIGITAL mode, when this option is enabled, the last caller callsign and channel contact are displayed each x seconds alternatively, in both Channel and VFO menus.
- Don't display CSS in header while DW scanning.
- Add APRS tx frequency support.
- When a TX Frequency is set in the APRS Config, the device is tuned to that frequency before transmitting the frame.
That permits setting an APRS Config to a DIGITAL channel (menuChannelDetails supports
that too).
- Also, a CODEPLUG_APRS_CONFIG_FLAG_TRANSMIT_QSY_INFO APRS Config flag is now supported,
which add QSY information to the beacon text (like frequency / tone / shift). Tested
on my TH-D74.
- NOTE: this is not enabled/supported while in Satellite mode.
- "APRS" word in the header had to be changed, since it could appear in DIGITAL mode too. It's now a "a", next to the mode.
- WARNING: The APRS Config version has been changed for this, so you need to read and write back your codeplug to update the APRS configurations, using the latest CPS (>= 2025 01 17).
- Fix DMR Rx AGC (wasn't disabled once enabled, until the transceiver got power cycled).
- Add special beeps when ReverseRepeater is enabled/disabled.
- Contact TS override has to be displayed, no matter the Display option "Info" is set.
- Many other small fixes/cleanups.
Version 7.3J
no function changes just some clean up of the code.
Version 7.3H
* On the Channel Details screen, the repeater Latitude and Longitude can be entered and also the "Use location" setting, can be set to Yes/No.
Note. the Use location is called "Location" because "Use location" won't fit on the screen
* Prevent Roaming channels re-sorting when a scan is ended.
* Updates to the Italian language translation
Version 7.3G
Increase number of nuisance entries during scan from 16 to 32
Change Auto Power Off step size and maximum time
Tx Inhibit
Handle if settings canβ™t be saved to Flash because of Write failure
Added automatic roaming function, based on position e.g. from GPS or manual entry.
Force re-sorting of channels in Roaming mode, my pressing Green button on the Roaming setting e.g Roaming:Manual
Show distance to a repeater / channel when button 8 is held down (long press)
Version 7.3F
Bug fixes for out of band transmit with VOX and possible transmit when in receive only mode.
Version 7.3E
This version fixes the bugs in the previous Beta release but it no
longer has the SMS passthrough functionality in Hotspot mode, becuase this was causing problems for normal operation
Version 7.3D
* Add Hotspot SMS passthrough function - Thanks for multiple authors including DL4LEX and Daniel for incorporating this change.
* Reinstate Private call alarm beep
* Add safe boot functionality (minimum functionality boot)
* Fix cursor Y position problem on RD-5R
* Fix Hotspot echo bug and change hotspot version number
* Fix DTMF tone cancellation problem
* Fix TimeSlot detection and synchronisation when TimeSlot filter is disabled

* Fixes volume control problems
* Adds Safe Boot mode (SK1 + 0) to be used when the radio will not bootup or bootloops.
* Fixes incorrect power level display on 10W radio versions
* Updates translations
* Fixes scan frequencies range boundary display problem
* Fixes voice prompt problem when replaying a prompt
* Fixes possible hanging problems associated with I2Cinternal bus contention
* Workaround for bugs in the C6000 DMR chip
Version 7.3B
Fixes an audio bug pluy a few other minor bugs. Needs the new voice prompt files.
Version 7.3A
Needs new CPS and voice packs
* Fixes a problem with reading and writing to the Flash memory which causes the radio to run slower than it should.
* Fixes problems of the VFO and Channel screen sometimes being blank
* Fixes problems with AT1846S TRx chip register cache system
* Fixes problem when attempting to transmit DTMF in satellite mode.
* Fixes QuickKey problems e.g. in VFO Dual Watch
* Updated multiple translations
* Romanian added. Note: The latest CPS is required to be able to select Romanian
* Adds Force DMO open to DMR channels.
This sets a channel to operate in simplex / DMO even when the Tx and Rx frequencies are different.
The CPS has also been updated to support this option.
All users should update because of the bug in the Flash memory access.
Version 7.2L
This version changes the operation of the Last Heard screen
Pressing the Green button changes the TG to the TG of the currently selected line
Pressing SK2 + Green changes the radio to make a private call to the station
Version 7.2K
Added APRS Beaconing feature plus lots of bug fixes in the APRS code.
Install the new CPS ( with password) and then the new firmware and new voice prompt files.
Version 7.2J
Changes in this version
* Channel order in zones can now be sorted by distance, using the Latitude and Longitude data entered into the CPS.
This works for all real zones, but Not the All Channels zone becuase this is not a real zone
Distance sorting is enabled via the "Dist sort" option in the Quick Menu
In this mode the distance is displayed in place of the channel number
* Distance can also be displayed at all times by using the "Show dist" option in the Display Options.
* GPS functionality has been added to the GD-77, DM-1801 and DM-1801 firmwares
None of these types of radios was originally available with GPS, so operators will need to fit a GPS module inside their radio,
and connect the data and power control connections directly to the CPU chip
GPS data needs to be connected to pin 99 and power control to pin 97. Becasue pins 98 and 100 are not used, it is safe, to bridge
between 97 and 98 for power control and between 99 and 100 for data, and bridging pins makes it far easier to solder to the CPU
I will make a separate post about retro fitting a GPS to the DM-1801 and GD-77
* Fixes and improvements to GPS course and accuracy display (Thanks to Daniel F1RMB)
* Czech language update
* Various other internal code changes and optimisations (Thanks to Daniel F1RMB)
Version 7.2H
There have been many other changes to the firmware and CPS
Remove APRS Destination from CPS and now use APOG77 built into the firmware
Add APRS ambiguity support in CPS and firmware
Add APRS support for 'Fixed position' location Lat/Lon in CPS and the firmware
Add APRS support for 300 Baud transmission.
Add Location Lat/Lon support to Channel data in the CPS and support in the firmware
MDUV380 shows distance in km from radio location to Channel Lat/Lon on the Channel screen.
GD77 and MD9600 the distance in km is shown if button SK1 (P2 on MD9600) is held in.
Note. The distance does not currently update if the radio changes position until the channel screen is reloaded. This function
will be improved in the future to automatically recalculate and redisplay the distance if it changes by more than 0.1km
MD9600 now supports short APRS comments.
Firmware character font Add missing N/n with Caron (F1RMB)
Fix frequency calibration bug on all radio types
Change APRS Tx method. SK1 is no longer required to transmit APRS.
Channels with and APRS config set, will now only transmit APRS, not voice and transmission of APRS is triggered simply by pressing the PTT.
APRS Tx ends immediately after the end of the data even if the PTT is held in.
Improve 'UI Notification' popup (F1RMB)
MDUV380 only Add volume control visual display, See Options->Display options-> Volume : Off/On (F1RMB)
Stop GPS NMEA output when CPS uploads/downloads the codeplug or other data (F1RMB)
Satellite mode APRS frequency will now only transmit APRS
It is no longer possible to send APRS on the 'Voice' frequency of satellites
Czech language updates (OK2MOP, Pavel )
CPS
Changes to APRS screen to remove Destination and add Ambiguity and Fixed position and 300 baud Tx
CPS has been updated to remove non functioning Tevel 1 and Tevel 8 satellites
Maximum number of satellites has been increased from 15 to 25
Channels can now have Latitude and Longitude values
Version 7.2G
Changes in this version are as follows
Bug fix APRS
Bug fix boot screen problem
Bug fix MD9600 1750Hz Tx problem
Bug fix DMR TA decoding
Add APRS setting to Channel Details screen
Added +/- 4.6Mhz repeater frequency shift
Improve MD9600 and UV380 1750Hz and DTMF tone indication through speaker
Improve satellite screen.
Maximum number of satellites has been increased from 18 to 25.
More satellites have been added to the CPS, e.g. TEVEL2,3,4,5 etc. Some nonfunctioning satellites have been removed.
Each satellite now has 3 possibly frequencies: Voice, APRS and Beacon, by pressing keys 1,2 or 3
APRS configuration is now defined for each satellite via the satellites.txt file in the CPS
To customise an APRS
configuation for a specific satellite e.g. "ISS" create an APRS configuration with the same name as the satellite, and this will be used instead of the APRS configuation for that satellite from
satellites.txt in the CPS
APRS Tx is possible on any satellite frequency where the Tx frequency has been enabled, but transmitting on the "Voice" frequency of a satellite e.g. ISS wil not result in your
position being sent to APRS.fi and will annoy anyone trying to use the Voice frequency of the satellite.
Turkish language updates
Czech language update
Various other small bug fixes.
Very Important
To use APRS and Satellite mode in this version, you MUST update to the latest CPS.
downloads/CPS/Latest/OpenGD77CPSInstall ... .18.01.exe
In this CPS you will need to re-create any APRS configurations and link them to the appropriate channels, then upload the new codeplug into the radio
In the CPS you MUST upload new satellite Keps
APRS Tx will NOT work unless a channel or VFO has an APRS configuation.
There is no longer a default APRS configration in the firmware.
Remember also. For APRS you must enter your callsign into the CPS. If there is no callsign then the APRS transmission will not be valid.

Version 7.2C
This version must be installed using the latest CPS from my package.
This version includes the Calibration option to accurately calibrate you frequency and power. Due to the small
screen the calibration in on more than one screen and you can move between them with SK2 plus up and down.
This version also includes the Talk around feature in the Quick menu so that when on a repeater channel
you can put the transmit frequency on the receive frequency.
Version 7.2B
The DM1701 version has some changes to the keypad operation and calibration option but has been moved to the OpenUV380 folder as the 1701 is more closely related to the UV380 than the
GD77.
Version 7.2A
There is now a version of the firmware for the DM1701 in the Other Radios folder and a new CPS which will work with the DM1701.
Version 7.1E
Minor changes and small bug fixes.
Version 7.1D
New CPS which allows the use of the new satellite FO118.
Version 7.1C
Minor changes to the TA function adding text to the position information.
Version 7.1B
this
version contains a new CPS which allows you to select various TA option in the channel informtion on a channel by channel basis. The default is master which uses whatever is selected in options menu of the radio.
Version 7.1A
if you
turn on Talker Alias in the options then the radio will transmit your location as well as your call-sign which allows the networkk to plot your position on an APRS map. This works on the DMR+ network and in Brandmeister if you go to self care and set your radio type to Hytera and GPS in Call to on.
Version 7.0S
In the CPS arbitary frequencies can now be entered rather than just 25/12.5 or 6.25Khz steps.
Version 7.0R
Firmware problem of not creating a new channel from the VFO correctly has been fixed.
Version 7.0Q
This fixed 2 bugs on the VFO screen
1. The Tx frequency was set to the Rx frequency when saving or writing to the radio, if the Tx frequency was different to the Rx frequency
2.
After fixing bug #1 above, I found that cross-band was still not possible, so that bug has also been fixed
Version 7.0P
New CPS to cure bug in selecting the Radioddity GD77donar file.
Version 7.0N
Quick keys have been added to the Quick Menu screen and a small bug fix.
Version 7.0M
New CPS with Ctr+u and Ctrl+d added to move items up and down in the zones screen.
Version 7.0L
It seems a few small bugs crept into the last version and have been fixed in this version.
Version 7.0K
some small bug fixes and you can now access the Quick menu using SK1 plus Green as well as the Orange button.
Version 7.0J
New CPS which allows you to use control u and control d to move items up or down when the zone list is on sthe screen.
Version 7.0H
A new CPS which allows you to move channels up and down in the Channels list window using Ctrl+u and Ctrl+d.
Version 7.0G
A new CPS which allows you to move channels up or down with ctrl+u or ctrl+d when the channels list is on the screen but only works in tree view and so is not really usable for the
blind at the moment and there are also some small bug fixes in the firmware.
Version 7.0F
New CPS program bnut the only changes affect the MD9600/RT90 and not the GD77.
Versuib 7.0E
A new CPS program to correct a small bug in the use of the Radio ID field.
Version 7.0D
Automatic power off feature added. Needs both firmware and voice prompt update. Holding the # key while switching on brings the radio up in voicing level 3.
Version 7.0C
When carrying the GD77 in a backpack for example the volume knob can accidentally be rotated and turn on the GD77 so a new option is in the General options called Safe power on. If
this is switched on then if you turn on with the volume control knob the radio just goes into suspend mode. To turn on the radio normally in this mode you need to hold SK1 while turning the radio on.
Version 7.0B
New CPS, Firmware and Voice packs. So you need to install all three. The CPS and GD77 Channel dedtails now allow you to turn on or off beeps and eco mode for each channel independently.
Version 7.0A

Version 6.0H
hopefully final fix for the rebboting problem.
Version 6.0G
New beta as a few people have reported rebooting and this version will hopefully fix the problem. However this only seems to affect a few radios.
Version 6.0F
Blind users should be aware there is a bug on the CPS channel screen when Radio ID is selected screen readers say Timeslot and when Timeslot is then tabbed too
only the contents (usually 2 is announced) not the label. This problem will be fixed soon.
