TX adjustment could be clearer

[chichimus]

Maybe I was having an off day but the directions on adjusting the TX could be clarified. I picked up a board and was trying it out with another ham. I took the "While pressing the PTT, have a look at the symbols graph of the m17_decoder module and adjust the baseband TX level until the blue dots line-up with the gray lines in the background" to mean all the blue dots in a single blue line mid screen and lined up with the grey lines. This was fairly quickly achieved with the direction I first turned the pot and thought I was good to go. Was getting nowhere until my friend sent me a screenshot of his and now I have it adjusted properly.
