Georgy,
Is this Mod also compatible with the latest Xiego Base Firmware, 1.1.8? If not, what has changed from 1.1.6 to 1.1.8? So what do we lose by using 1.1.6 with your Mod instead of the latest Xiegu software with Base 1.1.8?
I noticed that in your Github 1.1.6 repository, the README.md file does not specify that this Mod applies only to the 1.1.6 Firmware version, (if this is so, see above). You might want to add this to the README.md file. Assuming you need to apply the Mod to the 1.1.6 Firmware only, you might also want to add a paragraph to the beginning to indicate this, and maybe indicate that you need to "upgrade" to the Xiegu version that also includes the latest 1.1.6 Base Firmware, from the Radioddity.com site.

Hi.
I do some more changes on 1.1.6 BASE firmware - fix AM transmit, add a soft
limiter, output power control.
I decide to track changes within github repo:
Current version is rev1 (r1) - this suffix will be shown in the system info
instead of the build time for BASE version.
Some details:
* FM - depth of modulation increased 10 times. Output level configured to not
"disturb" ALC (reduced for ~ 13 times). Output power remains the same.
* AM - in theory carrier power should be 25% of the max output power with
modulation depth equals to 1. I made it about 50% of configured output power.
Guess, that positive peaks will be correct handled by ALC.
* Soft limiter for AM - I added it to prevent overmodulation. It adds some
distortion for a loud signal, but I guess it's a less evil than distortions
due to overmodulation.
* Output power is now affects a level of the generated IQ signals. Previously
- changing output power only changes ALC level, without actual changing signal
level.
Perhaps, I'll try to add FM squelch in a future version.
Also - I checked controlling compressor (on/off) from the alternative firmware
- it's working. I guess, ratio control will be configurable too.
