ATS-20 receiver updated with sketch V3.0.7g (ATS-20_bat_mod v2) by VE3XLT, CA2PEY and PU2CLR

I updated my ATS-20 receiver with sketch V3.0.7g (ATS-20_bat_mod v2) by VE3XLT, CA2PEY and PU2CLR. This sketch has the ability to indicate the remaining battery level in the lower right corner of the display, which is very useful. That function is enabled by adding a voltage divider circuit with two resistors to read the battery voltage, as shown in this video. The value is read from pin A2 of the Arduino nano in ATS-20 (Note: If this additional circuit is to be used permanently, access the back side of the board and place it downstream of the power switch as shown in the next video.    • ATS-20: Voltage divider circuit for b...  ).

I also removed bands that were unnecessary for me from the band list in the sketch.

If you would like to update sketch of your ATS-20 receiver yourself, I recommend learning about Arduino first. Then, I suggest you follow the instructions by Ricard Caratti linked below and use sketch in his Github pages. Once you get the hang of it, it would be easy to install sketches published on other sites also.
