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. [3]

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]
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]

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.
