Re: TYT MD-9600 / Retevis RT-90 : Experimental version

OK Well, you guys seem to be the only people who have 'hot' mic's on DMR as far as I'm aware. The default mic gain on FM may be a little high, but its only noticable on repeaters that use CTCSS as it can cause clipping due to overdeviation of the FM TX signal messing with the repeater's demodulation...

Re: How does one start porting the fw to another platform?

You can connect a programmer to the CPU in the radio, but you will not be able to read the firmware because all radios enable the Read Protection in the CPU You can erase the CPU but then your radio would be useless. With the GD77 etc, the encryption was broken by DG4KLU, but he keeps his methods se...

Re: TYT MD-9600 / Retevis RT-90 : Experimental version

Its very strange all of your radios have a very loud mic, when had no one else every had this problem

Are you using the mic that came with each radio.

Why do you have so many md9600?

I was receiving the bad audio reports on an analog VHF repeater. Any hardware issue that only affects DMR would be a different problem I believe.
Please explain in more detail.

Overdeviation and clipping because of CTCSS common. Try speaking quieter or reduce to the mic gain

Re: 能否添加中文语言

OK.

Not sure about RTC chips.

Perhaps there is a I2c chip you could use

Re: Font

One other possible option may be to add image display support, and store an array of images, which are used for the menus.

Re: 能否添加中文语言

You have made amazing progress with this. The reason the bottom of the character may be missing could be the Y position of each line being written to the screen All the values for Y position of the lines of the menu are designed for the height of the English font But I think that font is 8 x 16 (16 ...

Re: GD-88, the new Radioddity DMR radio

You mean some sort of terminal mode. In which case yes, but because you need to connect USB via the external speaker mic connections, people would need to make a special splitter cable and use an external mic Hardly anyone would bother to make this device, so its adding this sort of functionality is...

Re: GD-88, the new Radioddity DMR radio

There are already systems which will transcod the internet data to various other formats But the radio can't transmit or receive anything other than DMR. Exactly! The gd77 will still be in dmr but it needs an external bridge to do the other modes. It may just need some firmware that could improve t...
