Re: ALPHA TYT MD-UV380 / RT-3S Installation information

Be careful, maybe MD-390 and MD-UV390 are not identical. For example, the MD-390 has a Double Conversion Superheterodyne receiver whereas the UV390 has the Direct Conversion receiver.

Does anyone know what hardware the GD-88 is based on?

What CPU(s) / DMR / VFO / etc. and if it single or dual rx / tx hardware?

Here you can look inside this radio:

Re: GD-88, the new Radioddity DMR radio

Probably never. As you can see here, the device is only specified up to 480 MHz:

Re: GD-77 Firmware update path?

Thanks for Your answer!
As I've read in any instruction guides, first step is, to bring the device up to date with the original firmware.
Is it possible to startup from 2.06.03 to the latest OpenGD77 release?
Cause it's an older one, I don't want risk to brick it.

GD-77 Firmware update path?

Good evening from germany.

Please share your experiences with a absolute beginner.
Just got an older GD-77 with V 2.06.03 and DSP HRC6000 V 1.2.6
Which update path is useful and possible, straight to 3.2.2 (4.2.8/4.3.3/4.3.6?) or are intermediate steps required?
