The core design data of this tune comes from the automatic tune open source project of its original author N7DDC.




The finished kit is purely hand-soldered, provides 3.2 program support with SSD1306 controller, a resolution of 128x32 pixels, and a 0.91-inch diagonal monochrome OLED display. This circuit contains a set of 7 inductors and 7 capacitors, which allows it to work in a wider frequency range, effectively covering the amateur radio range from 1.8MHz to 50MHz.
