[Fixed] DMR Rx dropout
Re: ALPHA version - Known problems
Can anyone with the dropout problem, please try these versions
downloads/MDUV380/Firmware/speed_tests
They use different CPU clock speeds, and this seems to improve the dropout problem on my radio, even though the CPU clock speed in these tests is lower / slower than in the normal version

Re: ALPHA version - Known problems
I will start tests during this week and report my findings. Thanks for the developing the system to this radio.

Re: ALPHA version - Known problems
Hello. Please tell me what frequency is used in the factory firmware? Is it better to start testing with a high frequency?VK3KYY wrote: ↑Mon Sep 26, 2022 11:58 amCan anyone with the dropout problem, please try these versions

Re: ALPHA version - Known problems
We don't know for certain what speed the factory firmware uses because we don't have access to any of their source code.
The different CPU frequencies should not be noticeable, and for most people will not make any difference. For those who are experiencing the dropout issue it might help.
I would suggest trying them all and see if you can detect any difference.

Re: ALPHA version - Known problems
Vou testar e deixo o feedback obrigado.
Re: ALPHA version - Known problems
Thanks
Can you try the slower clock rates e.g. 96MHz as this will give bettery battery life, but perhaps has problems
Re: ALPHA version - Known problems
I haven't noticed any issues with the 144 or 120MHz versions. Loaded the 96MHz version to test this morning.
Update: I haven't had any break ups with the 96MHz version firmware.

Re: ALPHA version - Known problems
Thanks for the speed test versions!
Interesting to see others reporting on their good expericenes with the higher MHz versions...
I went from 144 MHz to 120 MHz and then tried the 96MHz. The 144&120 MHz versions still had dropouts on my RT3S (test setup as per earlier post). The 96MHz version appears to be stable with no dropouts since this early AM.
Just went back to 144 MHz for a quick cross-check and had another dropout after ~20 Min.

Re: ALPHA version - Known problems
There were failures at 144 MHz. Now I have been testing 120 MHz for 24 hours. There were no failures, most likely.
Re: ALPHA version - Known problems
OK
I am working on some more changes, but will probably use 96Mhz if possible, because it gives better battery life, because the CPU takes less current at lower clock frequencies.
