Description:
C: >-
<p>WSJT-X implements amateur radio communication protocols or "modes" called FT4, FT8, JT4, JT9, JT65, QRA64,
ISCAT, MSK144, and WSPR, as well as one called Echo for detecting and measuring your own radio signals reflected from
the Moon. These modes were all designed for making reliable, confirmed QSOs under extreme weak-signal conditions.</p>
<p>JT4, JT9, JT65, and QRA64 use nearly identical message structure and source encoding (the efficient compression of
standard messages used for minimal QSOs). They use timed 60-second T/R sequences synchronized with UTC. JT65 and QRA64
were designed for EME ("moonbounce") on the VHF/UHF bands; JT65 has also proved popular and effective for worldwide
QRP communication at HF. JT9 is optimized for the LF, MF, and HF bands. It is about 2 dB more sensitive than JT65 while
using less than 10% of the bandwidth. With either JT9 or JT65, world-wide QSOs are possible with power levels of a few
watts and compromise antennas. JT4 and QRA64 are optimized for EME on the VHF and higher bands, and especially the microwave
bands from 2.3 to 24 GHz.</p>
<p>FT4 and FT8 are operationally similar but use T/R cycles only 7.5 and 15 s long, respectively. MSK144 is designed for
Meteor Scatter on the VHF bands. These modes offer enhanced message formats with support for nonstandard callsigns and
some popular contests.</p>
<p>WSPR mode implements a protocol designed for probing potential propagation paths with low-power transmissions. WSPR
is fully implemented within WSJT-X, including programmable "band-hopping".</p>
