Answer Notes
According to the commonly accepted amateur radio band plans, the 20-meter band is heavily utilized for various data and digital modes. These operations are traditionally clustered just above the exclusive CW (Morse code) segment.
Specifically, the frequencies between 14.070 MHz and 14.100 MHz are the recognized sub-band for digital operations. This is where you will find the vast majority of FT8, PSK31, RTTY, and other digital mode traffic.
Contrasting this with the distractors: 14.230 MHz is known for Slow-Scan TV (SSTV) but is located within the phone (voice) segment. 14.100 MHz is the traditional International Beacon Project frequency, and CW operations dominate the space below 14.070 MHz.
