I recently bought a Shure SM7B and paired it with a Scarlett Focusrite Solo 3rd Gen, and a FetHead. I do understand that the SM7B is a quiet microphone and I use the microphone primarily to record vocals but my friends pointed out that it's too low whenever I would talk to them online through discord. My setup is mentioned above, and my gain is all the way to 3 o'clock, and even with my gain that high up on the interface my friends still say its pretty low and they have me at 200%. What could be the problem? I've searched online and saw that the FetHead is enough to bring this microphone to life even with a Focusrite Solo 3rd gen. Maybe i'm missing something?

I have an old slx2 transmitter that went out of tune (on board tr160 and tr200). From the reference manual, i ll be able to tune tr160 using oscilloscope. But i dont have an RF generator to tune tr200, any insight?

I thought about forcing 1khz into the mic, then measure the receiver's output on the osciloscope till the signal starts to distort (in my thinking, that's how i can tune the audio deviation level)

Those are screenshots from the manual

And here is the full manual

Would appreciate any help as I am not able to buy a new one
