JT6M.org - The purpose of this web site is to promote JT6M as a mode of communication on both 6M and 4M band and guide users through setting up and using JT6M effectively. Optimised for 6 metre band Meteor Scatter, JT6M allows you to make meteor scatter contacts easily. JT6M is part of the WSJT suite of digital weak signal software applications developed by Joe Taylor, K1JT
