Re: TYT MD-UV380 DMR Rx Missing

You seem to be right, I just checked, the relay indeed is a MMDVM.
But the manual states:
In DMR mode the signal meter will only be active when the DMR hardware detects a DMR signal.
So I guess that either the manual or the code should be adapted.

Re: TYT MD-UV380 DMR Rx Missing

I've seen something similar on my MD-UV390. RSSI bar comes to life, green LED lights up but no voice is received. Not in monitor mode, not with all set to filters off manually. But there is something audible on FM that sounds like faint DMR. Hypothetically, if someone used encryption on a ham relay,...

MD-UV380 Source

Hi all, sorry to be the guy that aks THAT question again but.. Is there any chance to get the source code for the latest MDUV380 release anytime soon? I successfully compiled the available source (R20230311) and uploaded it to my MD-UV390G but unfortunately noticed, that a lot of things are out of d...

Re: TYT MD-UV390 Installation Hint

Oh. I only now realized that there are 3 buttons on the left side ;)
Maybe it was a coincidence that I pressed PTT+upper button when USB was disconnected.
Sorry for the confusion.

[Incorect information] TYT MD-UV390 Installation Hint

Hi, I just installed OpenGD77 (R 2023-11-19) on a TYT MD-UV390 with GPS, but I had to do something that was not explicitly mentioned in the user guide: Power on the radio while holding down both buttons on the left side WITHOUT USB CONNECTED ! Then the screen will stay black and the LED starts blink...

Re: SCT3258 Baseband IC

Do we by any chance know the hardware differences between the different versions of the AnyTone 878 like UV, UV+, UVII+ ?

Re: Auto-channel tuning by GPS location

I like the general idea! Although I think the „shadow zones“ as you proposed them are hard, if not impossible to implement. I would instead attempt to combine distance to relay station with RSSI or BER. Just save a list of relais with their GPS coordinates. Try closest relay first (theoretically hig...

Re: DMR Data Mode

Just out of curiosity; since short messages are supported by the original firmware of the GD77, did anyone ever attempt to sniff and reverse engineer the communication between the MCU and the Baseband IC with a logic analyzer while sending a SMS?

SCT3258 Baseband IC

Hi all, I just want to drop something here, the files below contain what seems like fairly comprehensive documentation for the CT3258/SCT3258 DMR Baseband IC: cdn.hackaday.io/files/1642237026116832/SCT3258_datasheet_v2_0.pdf cdn.hackaday.io/files/1642237026116832/CT3258_datasheet.pdf cdn.hackaday.io...
