The 10-meter band was allocated on a worldwide basis by the International Radiotelegraph Conference in Washington, DC, on 4 October 1927. [2] Its frequency allocation was then 28-30 MHz. A 300 kHz segment, from 29.700–30.000 MHz, was removed from the amateur radio allocation in 1947 by the International Radio Conference of Atlantic City.
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.

GB3RAL, which is located at the Rutherford Appleton Laboratory, transmits continuously on a number of low-band and mid-band VHF frequencies – 40050, 50050, 60050 and 70050 kHz – as well as 28215 kHz in the 10-meter amateur band. [15]
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.
Amateur radio, also known as ham radio, is the use of the radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communications. [1]
