We know some of you (the Radioddity DB25-D customers) had been waiting already quite long to get a fresh firmware update for your radio. Whereas the latest Radioddity GD-88 customers already got some minor updates within their radios perhaps even not knowing about. But now we got it all together and ready for your weekend to be checked out.

The feature we are most proud of is the long-awaited support of Talker Alias. The firmware files for both radios (DB25-D and GD-88) have the initial Talker Alias implementation available for you to check out. The implementation has not yet reached the level we want it to be (e.g., support for international characters not yet supported) but we did not want to keep you waiting any longer for that often-requested feature. That´s why we decided to already release it at this early stage. You are welcome to give us feedback on the current implementation of Talker Alias.

Now it is also possible to stay in the radio menu even on an incoming call.

Besides that, additional Pilot Tones are now supported as P-Keys for operating repeaters that do not require the standard 1750 Hz one.

The updated CPS no longer crashes if you are using a screen resolution of more than 1080x1920 and of course it does support the additional pilot tones.

And of course, our extended manual for the Radioddity DB25-D and GD-88 has also been updated with full details on all those new features plus a lot more.

Furthermore, we have updated our default codeplugs. You find those together with our CPS as .F136 files to be used with the Radioddity CPS and as JSON-files to be used with the CPEditor of David MM7DBT as his newest version already does support the new features as soon as you have updated your radio's firmware.
