A waterfall display showing FT8 in use on the 40-meter band. FT8 (short for Franke-Taylor design, 8-FSK modulation) is a frequency shift keying digital mode of radio communication used by amateur radio operators worldwide.
A Yaesu FT-891 Radio Tuned to the 10 Meter Band. The Yaesu FT-891 is a HF and 6 meters all mode mobile amateur radio transceiver. The FT-891 was first announced to the public by Yaesu at the 2016 Dayton Hamvention. [1] The radio has 100 watts output on CW, SSB, and FM modulations and 25 watts of output in AM. [2]
A waterfall plot for FT8 signals (bandwidth 50 Hz) in the 40-meter band and for JT65 on the right (bandwidth 180 Hz) Joe Taylor, K1JT, announced on June 29, 2017, the availability of a new mode in the WSJT-X software, FT8. [11] FT8 stands for "Franke-Taylor design, 8-FSK modulation" and was created by Joe Taylor, K1JT and Steve Franke, K9AN.

The 8–meter band (40 MHz) is at present the lowest portion of the very high frequency (VHF) radio spectrum available for national amateur radio use. The term refers to the average signal wavelength of 8 meters. The 8–meter band shares many characteristics with the neighboring 6–meter and 10–meter bands.
The 10-meter band is a portion of the shortwave radio spectrum internationally allocated to amateur radio and amateur satellite use on a primary basis. The band consists of frequencies stretching from 28.000 to 29.700 MHz.
The list of frequency ranges is called a band allocation, ... 80 metres or 80 / 75 meters – 3 500–4 000 kHz – 85.65–74.95 m actual; Best at night, with ...
As a matter of convention, the ITU divides the radio spectrum into 12 bands, each beginning at a wavelength which is a power of ten (10 n) metres, with corresponding frequency of 3×10 8−n hertz, and each covering a decade of frequency or wavelength. Each of these bands has a traditional name.
