Re: S Meter max with Nextion and CEC V 1.2

 

Just a thought. The audio level is tapped off from the output of the agc board. Meaning that the agc will be attuniating a signal over S9 therefore it tops off at S9. If you want to read the real signal strength then you should tap the signal off at the input to the agc board. I have not yet experiment with this idee yet.

Justin,

If you have a Nextion display, have you tried monitoring the ADC as Ian (KD8CEC) does in this blog:


It might give you some more information to figure out if it is a sensor or software issue.

I did the LM358 sensor modification for a friend on a v6 ?BITX.? Since all of the audio signals and controls are on the mainboard, the audio header is open.? I used that to mount a small board with the LM358 opamp as in this picture:


Just a suggestion and some more information.
