Ham Amateur Radio Technician Practice Exam

Which of the following is a common location for FT8?

1. Approximately 14.040 MHz to 14.050 MHz

2. Approximately 14.074 MHz to 14.077 MHz

3. Approximately 14.100 MHz to 14.120 MHz

4. Approximately 14.060 MHz to 14.070 MHz

The correct answer is: Approximately 14.074 MHz to 14.077 MHz

FT8 is a digital communication mode popular among amateur radio operators, particularly for weak signal communications and during times of low band activity. The frequency range of approximately 14.074 MHz to 14.077 MHz is specifically designated for FT8 operations on the 20-meter band. This range is often used for calling and making contacts in FT8 mode, as it's one of the frequency allocations recognized and utilized by operators for this type of digital communication. This allocation helps facilitate organized and effective use of the band for FT8, allowing operators to quickly find and make contacts while minimizing interference with other modes of communication. The specific frequencies within this bandwidth are chosen due to their efficacy for FT8 signal transmissions, which are characterized by their narrow bandwidth and the ability to decode signals that are very weak or heavily distorted by noise.
