Franke-Taylor design, 8FSK modulation

The new mode is named after its developers, Steven Franke, K9AN, and Joe Taylor, K1JT. The numeral designates the mode’s 8-frequency shift keying format. Tones are spaced at 6.25 Hz, and an FT8 signal occupies just 50 Hz. Unlike JT65 or JT9, transmit and receive cycles in FT8 each last about 15 seconds. Like JT65, FT8 requires accurate time synchronization. An auto-sequencing feature offers the option to respond automatically to the first decoded reply to your CQ.(ARRL)

Software installation

To install the WSJT-X Software on Windows, Linux (also on RasPi) and Mac-OS follow these instructions.
On Ubuntu 14.04 LTS the version 1.9 seems not to be able to be installed because of unsolvable dependencies.
Install v1.8 as follows:

Add PPA .......: sudo add-apt-repository -y ppa:ki7mt/wsjtx-next
Update ........: sudo apt-get update
                 (ignore the errors because of missing release notes)
Install .......: sudo apt-get install wsjtx

Time synchronization

Synchronization of computer clock with Internet time servers by NTP service is very important for using digital operation modes.
Installation of NTP on Windows Platform
Installation of NTP on Ubuntu
Installation of NTP on Raspberry Pi
Use as time server in Austria:
Prepare /etc/ntp.conf as follows:
# Use servers from the NTP Pool Project. Approved by Ubuntu Technical Board
# on 2011-02-08 (LP: #104525). See http://www.pool.ntp.org/join.html for
# more information.
server 0.at.pool.ntp.org iburst
server 1.at.pool.ntp.org iburst
server 2.at.pool.ntp.org iburst
server 3.at.pool.ntp.org iburst

if ntpq produces time out errors:
$ ntpq -pn timed out, nothing received
***Request timed out

please see note under https://www.eecis.udel.edu/~mills/ntp/html/accopt.html
parameter "noquery" and delete it from /etc/ntp.conf
