in MD380 firmware stops updating display for as long as its receiving. and you can even hear it if you put another radio nearby with open squelch.
That's not exactly ideal for a radio.

It would mean we can't show the signal level bar graph during reception as it could cause interference to the reception :-(

yeah, and also neither Ty, nor the Z-fork author-borrower did a "stop display when backlight off" patch, so i cant keep 380 close to anything analog if i need to listen to multiple signals at once. gotta try shielding everything with metallic tape once i get a replacement lcd for it (mine suddenly went south when radio was sitting on the desk scanning)

wonder if DM1702 suffers from it as they use soldered display instead of socketed in 380/390/HD1

I have an MD-390 on which the screen went blank one day.
I repaired it with a hot air iron and a small metal stick, to "resolder" the flat-flex back on the glass. Since then, it works.


Cheers.

I can see why people are attracted to the RT-3S, because of the low price and the fancy colour screen, however I personally using coloured screens outdoors is a big problem with the very strong sunlight we have here in Australia, hence why I like the GD-77 and other radios with a black and white display.
I definitely agree that a black and white screen is better than color for a radio. Color means you have more choices for how you display things, but having more choices really just means you need more skill in UI design to make an interface that doesn't confuse everyone or isn't readable by people with color vision deficiencies. The icons on the MD-380 and friends make little sense to me most of the time.

Just my 2 cents: I vote for high contrast UI, with a possibility of reverse mode.
I hate these fancy/unreadable multi-colored UIs, like the one in the MD-3{8,9}0, you can't read anything under sunny conditions.
The one from the TH-D74 is really nice, but it's a transflective screen, not the same ballpark...

I have experimented with ePaper displays, but they are a bit too slow for this application.

Guys.

FYI.

I just ordered a RT-3S from AliExpress, but it will take between 3 and 6 weeks to arrive.

Ty Weaver has now cracked the encryption on the MD-9600 which he tells me uses the same encryption as the MD2017 and the UV-380 , and the UV-380 and RT-3S are the same radio.

So I am hoping that with this information I can upload firmware into the RT-3S
I am happy that the encryption on the MD-UV380 got broken, me and IU2KWO have a pretty much complete support of the MCU by now,
including display drivers. So porting to the MD-UV380/RT3S and MD-9600 is now definitely possible, because they even have the known HR_C6000 baseband.
However, I must correct you Roger, the MD-9600 has not the same encryption of the MD2017 and UV-380.
MD2017 and UV-380 have the same, MD-9600 encryption is different, as proves this pull request.
Nonetheless we still have the keys, so hopefully we'll start porting soon!

One question, is the Baofeng DM-X the same radio?

has not a 16 position button... maybe is the 1702??
