Tytera MD-UV380: backlight on AFTER squelch close

[Remon]

I have a TYT MD-UV380 with the following issue:

Screen backlight is set at 15 seconds. While tuned on an analog channel with the backlight in off state, it doesn't lit up when receiving a signal. It lights up AFTER the transmission when the squelch closes.

I'm not sure if this is the default behavior, a bug in the firmware or an overlooked setting in the CPS?

No tone squelch is used. On digital DMR mode channels the screen light up immediately.

I did some additional tests:

Programmed CTCSS decoder on a channel and transmitted with another radio on that channel. In this scenario the screen lit up immediately.

On channels with all CTCSS or DCS setting to none the display only lit up AFTER the transmission when the squelch closes.

It lights up AFTER the transmission when the squelch closes.

Have you tried another firmware, like some of the experimental ones? You can never brick the radio by doing something wrong as you can always load the original firmware back into it.

I can see the same phenomen in a SDS100 scanner, that in some mode the backlight turns on after the call.

The experimental ones are for the single band MD380's? I tried re-flashing to radio with both the most recent (V018.011) CSV and REC firmware. I also tried it with older versions from 2019. No luck with that unfortunately.

No, there are versions that support both MD and UV models and the versions with and without GPS.

My MD-UV380s in analog mode: (1) screen lights up when pressing tx key and stays lit for a few seconds; (2) screen lights up when receiving a signal, e.g., a repeater ID or someone on the air, and stays lit for a few seconds.

FWIW I have never found a reason to update firmware. One radio about 2.5 years old, the second about 1 year old.

HTH.

Thanks for testing. Do you have a GPS or non-GPS version?

I bought a Retevis RT3S and didn't touched the firmware neither I connected it to my computer: same problem. A Retevis RT3S GPS is on it's way because it has a different firmware with a higher version number. If that doesn't work also an Ailunce HD1 GPS is on it's way..

I also finally got a response from TYT (after I ordered all the radio's..) and they can reproduce the problem I had. They expect a new firmware ready for testing in a week.

Soon I have some radio's for sale..

The GPS version came in the mail today: same bug.

Sorry, didn't see your question until now. My 2 MD-UV380 units are non-GPS. I have no interest or need for GPS.

I consider the MD-UV380 to be a bulletproof radio (as is the M380). I hear the locals complain about the endless updates to the various Anytone radios.
