The segment of the 20 meter band from 14.070 to 14.100 MHz is primarily designated for digital modes and data transmissions. This frequency range has gained popularity among amateur radio operators who use various digital communication protocols such as PSK31, FT8, and RTTY. This segment provides a suitable environment for these modes due to generally less interference and the ability to effectively transmit low bandwidth data.

Additionally, the choice of this frequency range aligns with the allocation rules set by the International Telecommunication Union (ITU) for amateur radio, which reserves certain segments for specific types of operation. While the other segments can be used for voice and other forms of communication, the 14.070 to 14.100 MHz range is specifically recognized and commonly utilized for data comms, thereby making it the preferred choice among operators engaged in those activities.
