an extended and experimental branch of the program
_WSJT_.
_WSJT-X_ Version 1.7 offers eight protocols or modes: *JT4*,
*JT9*, *JT65*, *QRA64*, *WSPR*, *ISCAT*, *MSK144*, and *Echo*. The
first four are designed for making reliable QSOs under extreme
weak-signal conditions. They use nearly identical message structure
and source encoding. JT65 and QRA64 were designed for EME
("`moonbounce`") on the VHF/UHF bands and have also proven very
effective for worldwide QRP communication on the HF bands. QRA64 has
a number of advantages over JT65, including better performance on the
very weakest signals. We imagine that over time it may replace JT65
for EME use. JT9 was originally designed for the LF, MF, and lower HF
bands. Its submode JT9A is 2 dB more sensitive than JT65 while using
less than 10% of the bandwidth. JT4 offers a wide variety of tone
spacings and has proved very effective for EME on microwave bands up
to 24 GHz. All of these "`slow`" modes use one-minute timed sequences
of alternating transmission and reception, so a minimal QSO takes four
to six minutes — two or three transmissions by each station, one
sending in odd UTC minutes and the other even. On the HF bands,
world-wide QSOs are possible using power levels of a few watts (or
even milliwatts) and compromise antennas. On VHF bands and higher,
QSOs are possible (by EME and other propagation types) at signal
levels 10 to 15 dB below those required for CW.
