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.
