Audio problem
Re: Audio problem
been doing some messing.
it would appear that the buzzing appears if the screen brightness is anything other that 100%, however, when the screen is at 100% the buzzing is replaced with a high pitched tone.
With the screen at less than 100% the buzzing is there until the screen goes off. When at 100% the high pitched tone is there and reduces when the screen goes off, but is still audible.

Re: Audio problem
I don't think anyone else has this problem, hence it may be specific to you own radio
How old is the radio?

Re: Audio problem
Not sure on the age, I will try on a different radio and see if it is still present. definitely when the backlight is on, but wasn't there in the original firmware.
i will get it back to stock and see if its still present

Re: Audio problem
The official firmware does not support dimming of the display. What you are hearing is probably an artifact of the PWM used for the dimming
But AFIK no one else's radio has this artifact

I encounter exactly the same behavior on my TYT MD2017.m0xrs wrote: ↑Tue Apr 16, 2024 7:22 pmbeen doing some messing.

It's a early model, bought it in summer 2017.
I was told, this buzzing sound is even in the transmissions. Until the backlight switches off.
