What is FT8?

FT8 is a digital communication mode that falls under the umbrella of Amateur Radio, commonly known as Ham Radio. Developed by Joe Taylor (K1JT) and Steve Franke (K9AN), FT8 is designed for reliable communication in weak signal conditions.

FT8 utilizes a highly efficient modulation scheme known as 8-Frequency Shift Keying (8-FSK) to transmit and receive data. This mode operates on 8 different frequencies, each representing a specific symbol, which allows for robust error correction and decoding of weak signals.

The primary purpose of FT8 is to make contacts, or QSOs, with other Ham Radio operators in various locations around the world. It enables efficient long-distance communication, even under poor propagation conditions. By using FT8, Ham Radio enthusiasts can reach out to other operators using very low power and basic antenna setups, opening up new possibilities for communication.

One of the distinguishing features of FT8 is its automated exchange of information. The mode uses predefined message formats to transmit information like callsign, signal strength, and location. This automation reduces the need for manual input, allowing quick and reliable contacts to be made.

With its short transmission cycle of 15 seconds and quick decoding time of just a few seconds, FT8 enables operators to make a large number of contacts in a relatively short period of time. The efficiency and reliability of FT8, coupled with its ability to operate under challenging conditions, have made it a popular choice among Ham Radio operators around the world.

FT8 has also gained recognition among researchers and enthusiasts in other fields, such as astronomy and meteorology, due to its ability to detect and decode weak signals from space-based or terrestrial sources.
