Radio gets noise on RX when on Battery Alternative Firmware v0.28.0

 

I have a strong noise on all bands when using Battery with Alternative Firmware v0.028.0
-Problem is shown on RX.
-I don't see that on TX but I hear my own voice on the speaker if I call SSB. Monitoring level is at 0.
-Shows up at beginning of the band and at the end.
-With or without antenna.
-Noise goes to minimal, but still there, when the screen dims out after a few seconds not touching the VFO or any button in the radio.
-Goes up again, as soon as I wake up the radio by touching the VFO or any other button.
-Goes off as soon as I plug in the external power.
?
In brief: The problem is not there or does not show up if using external power.
With Battery the radio shows 7.8V on the screen.
With external power shows 13.6V on the screen
Happens in all bands.
Not happening with standard Xiegu Firmware
App V1.1.9 Sept 14 2024 12:11:57,
Base V1.1.8 Sept 15 2024, 15:22:37

I made a video that shows the problem live for you to see.
?
Suggestions what could be happening are welcome.?

Just looked at your youtube video. At 21.074 I get birdies at exactly the same place as your noises. However, Not as strong.
Both 0.28 and original Xiegu firmware have those birdies at the same signal strength on mine.

The problem is that I have that strong noise you saw on the video in all bands and, when moving the VFO, both signals, the one at the beginning of the band width shown in the screen and the one at the end, both follows the movement up or down. Those two are always present on the screen, no matter which band you are on. Again, this only happens when on battery and only when the alternative firmware is in use.

I have seen this problem on my x6100 from day one with all of the software versions I have used?

This is a hardware design issue. I just live with it?
