as you can see in the SG-Lab data sheet, the vox already works with 1mW input, so it only needs a low level to switch PTT. Your CN0417 module with approx. 20dB ampli generates a maximum of 50mW from the approx. 2mW of Pluto, which has been attenuated by 6dB. This is perfectly sufficient to fully drive the PA. Depending on the transmitting antenna used, the level on the QO-100 is much too high and the Leila is activated. Here you should set the maximum levels for Gain, Drive, etc. accordingly in the settings "Transmit - Options - Audio-in - Gains".
I hope this is of some help, if Mr. Google translated everything correctly
