Yeah, bud I have been looking into and playing with the sound_volume function of the sbitx_sound.c file.?

it looks like this is where the two come together, I'm not that good, but it looks like it comes down to this simple mapping but Idk it's anything?but linear in practice on my set.?

are you seeing the same??

? ? snd_mixer_selem_get_playback_volume_range(elem, &min, &max);
? ? snd_mixer_selem_set_playback_volume_all(elem, volume * max / 100);

JJ quick question for you man. ( And anyone else that can check for me..)

Can you check your volume scaling for me??

I wonder if I'm the only one with the issue where the Audio% in sBitx is skewed?from the value presented from the Volume control?

I ask because I noticed this behavior today?so I chased after it.?

?

Undid everything I had done in the past few days. The only thing that remains unchecked is the ATTiny85 I don't?know what is saved in EEPROM on that. it looks to be hitting the pi over I2C but I haven't?looked at the code?yet to identify its utility purpose.

If anyone reading this post has an idea please feel free to chime in. I have emailed Ashhar and briefly mentioned it but this seems out of my reach to diagnose beyond what I have mentioned,

Thanks for your consideration.

Hi Jon

I turned off and excluded I2C from the beta build because I was seeing errors in the logs.. I don't know if this is more left over code from previous board revisions or not.. My build seems to function without it for SWR measurement. I know Rafael's build includes it and there are errors..?

The code for the SWR bridge is in swr_bridge.ino to my understanding. I am by means no expert here, but I think the sketch is only used to program the ATTINY85 bootloader from the factory? It looks like you may have figured that out already and have a better grasp on it than I do. I am still figuring out a lot of things with this radio :)


Again - thank you for taking time to help and test! My future versions will include a special thank you message to all of those who helped.
