OpenMD9600 User Interface

OpenMD9600 Voice Packs

TYT MD9600 Firmware

RT90 Driver

Version 3.4B
Fixes an audio bug plus a few other minor bugs and needs the new voice prompt files.

Version 3.4A
Needs new CPS and voice pack
* 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 theTx 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 3.3M
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 3.3L
Added APRS Beaconing feature plus lots of bug fixes in the APRS code.
Install the new CPS first then the firmware and the new voice prompts.

Version 3.3K
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
* 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 3.3J
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 )
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 3.3H
This version fixed the 1750Hz 'tone burst' low deviation bug
It also improves APRS deviation
And also fixes Tx frequency offsets when transmitting 1750Hz tone or APRS
Additionally, the calibration screen user interface has been changed so that it is the same as the GD77.

Version 3.3G
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 3.3C
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 3.3B
Problem with the DCS Rx decoding fixed. Plus Settings storage is now in Flash memory rather than battery RAM, so battery problems don't cause loss of settings and manual backlight toggle as been assigned to button P2 on the front of the radio.

Version 3.3A
this version of the firmware will run on the older MD9600/RT90 with the original STM microprocessor and also on the new MD9600/RT90 using the Chinese Clone microrocessor. In the menu item Firmware Information there is an extra line CPU then either STM for original or TYT for Chinese Clone.

Version 3.2D
New CPS which allows the use of the new FO118 Satellite.

Version 3.2C
New GPS screen and minor changes to the TA function with text added to position information.

Version 3.2B
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 3.2A
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 3.1P
fixes a small but with using the D key on the microphone to create latch sk2.

Version 3.1O
DTMF ABCD keys mapped to same keys as GD77 and UV380 plus new CPS with minor modificaitons.

Version 3.1N
In the CPS arbitary frequencies can now be entered rather than just 25/12.5 or 6.25Khz steps.

Version 3.1M
new CPS program from 16/10/22 and in the firmware improved scanning speed and several small bugs fixed.

Version 3.1L
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 3.1K
small fix for the GPS.

Version 3.1J
Multiple bug fixes

Version 3.1I
New CPS which cures a bug which does not affect the MD9600/RT90 only the GD77.

Version 3.1H
New CPS with Ctrl+u and Ctrl+d to move items up and down in the Zones screen

Versuib 3,1G
Contains a number of bug fixes.

Version 3.1F
New firmware version so you can now start a scan by holding the up arrow while in Channel mode.

Version 3.1E
S meter corrected to give more accurate results over S9 with Version 5 radios.

Version 3.1D
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 3.1C
A new CPS which allows you to move channels up and down in the Channels List Window using Ctrl+u and Ctrl+d.

Version 3.1B
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 it only works in tree view at the moment so not really usable for the blind and there are also some small bug fixes in the firmware.

Version 3.1A
the standby current has been reduced from 100mA to around 19mA. Also with the radio switched off but power applied you can enter firmware upload mode by holding the orange button and P1 and then pressing and releasing the power button on the front panel.

Version 3.0J
New CPS programm which includes the firmware loader so no seperate loader program is needed.

Version 3.0H
Corrects a bug which after settings update caused the radio to come up in beep mode even when the voice pack was present and also the transmit mic gain in FM mode has been reduced by 3db. Holding the # key while switching on brings the radio up in Voice Level 3.

Version 3.0G
New CPS Program to correct a small bug in the use of the Radio ID field.

Version 3.0F
Automatic Power off feature added. Needs both firmware and Voice prompt update.
