Exactly, the Kydera is a true dual band. It can receive DMR or FM at the same time on each side and has independent digital volume control.
They even make an LTE/WiFi version of the same model.
But the DB-25G is not a true dual-band.
I would also like the return of real dual bands with 2 physical volume controls, each with its own Squelch.

My first dual band radio was the Standard C550 (Asian version of the C558A, which I also acquired lately as a spare as the old one was getting bad) and it has cross band repeat. I bought it in 1993. It was not that uncommon back then, as a matter of fact, almost all dual band HT models during that era all could do cross band repeat. My other models that I have owned and still owned today, have these: Alinco DJ-580T (owned 2 i diff time frames), Icom IC-24AT (had been having problems), Yaesu FT-51R. I have also owned Yaesu FT-470, iirc, also has that feature.
The Standard C558A was really a good radio for its time.
Cross-band repeat was also interesting in the 1990s. And you could often just plug in a simple 12v power cord to operate and charge the radio. No need for Battery Eliminator and another charger...
It would be interesting if the GD-77 could serve as an interface to connect to the Raspberry Pi for communicate digitally via the Internet on various networks. It couldn't do it in RF given the architecture but could do it otherwise.
A bit like the Node-Ventures and the interface they created that will connect to the Raspberry with a speaker and microphone that will allow you to talk on various digital modes via the internet. We replace the module and take the GD-77.
The tools are already there with among others MMDVM_Bridge and Analog_Bridge from DVswitch.
It would just be necessary for the GD-77 to be able to talk to the computer and the radio could surely do even more without having to make heavy physical modifications.
An idea like that in order to make it evolve even more since it is itself limited, it will then need external tools to do even more in a radical way.
