Updated Radio 1x1 monitor.

Optimized the code, adjusted the colors of the incoming radio signal level bars. Changed the color of the radio channel selection buttons to gray. When pressed, the color of these buttons is light blue. The inscription "CH" is now light yellow. Also, the color of the "Transm" label was made darker (during transmission).

When you click on the inscription "Transm", the voice transmission mode is activated in the form of a radio signal!
