A new GD77/DM1801/RD5R radio Beta is available

There are significant changes in this release which effect all radios, not only the GD77/DM1801/RD5R and also effect the CPS

Because there was almost no ROM space remaining in the GD-77 and similar radios, including the DM-1801 and RD-5R, we had to change how non-English languages are supported.

The firmware now only includes English + one other 'additional' language. The 'additional' language is now merged into the firmware by the CPS, when it is uploaded into the radio

The data for each language is stored in separate files e.g. French.gla , and the language file version must match the language version in the firmware

So that the language and firmware files are kept together we are now using .zip files

Each zip file contains the firmware bin file and all supported language .gla files

The new CPS, released today downloads/CPS/Latest/OpenGD77CPSInstall ... .04.01.exe now supports .zip as well as .bin files

In the CPS firmware loader screen, there is a dropdown menu to select the additional language to me merged into the firmware

Linux users are supported by use of these Python based loaders

Thanks to Daniel F1RMB for all his work modifying the firmware, making new build tools, and also updating the CPS and Linux tools.

In addition to the this big change, 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


Voice prompts
• Czech language updates (OK2MOP, Pavel )


Edit. There was a Tx APRS lock bug when no location was set.

I'm going crazy, I downloaded the latest version of the CPS and the FW to install it on Tytera UV-MD380 with GPS, doing the usual "firmware loader" operation (done dozens of times) in the end the radio stays with the display off. If I load the previous version all ok! I haven't tried it on MD-9600 since what happened, am I the only one having this problem?

This topic relates to the GD77 but you are trying to load on to an MDUV380. Are you sure you have downloaded the correct version of the firmware?

This version has now been superseded with a bug fix version
