correct decoding down to S/N = 22 dB and 50% at 24 dB. JT9 is about
2 dB better, achieving 50% decoding at about 26 dB. Both modes
produce extremely low false-decode rates.
JT65 signal reports are constrained to the range 1 to 30 dB. This
range is more than adequate for EME purposes, but not enough for
optimum use at HF and below. S/N values displayed by the JT65 decoder
are clamped at an upper limit 1 dB. Moreover, the S/N scale in
present JT65 decoders is nonlinear above 10 dB.
By comparison, JT9 allows for signal reports in the range 50 to +49
dB. It manages this by taking over a small portion of ``message
space'' that would otherwise be used for grid locators within 1 degree
of the south pole. The S/N scale of the present JT9 decoder is
reasonably linear (although its not intended to be a precision
measurement tool). With clean signals and a clean nose background,
JT65 achieves nearly 100% probability of correct decoding down to
S/N = 22 dB and about 50% at 24 dB. JT9 is about 2 dB better,

.JT9 Protocol and Implementation
JT9 is a mode designed for making minimal QSOs at LF, MF, and HF. It
uses 72-bit structured messages that are nearly identical (at the user
level) to those in JT65. Error control coding (ECC) uses a strong
uses 72-bit structured messages nearly identical (at the user level)
to those in JT65. Error control coding (ECC) uses a strong
convolutional code with constraint length K=32, rate r=1/2, and a zero
tail, leading to an encoded message length of (72+31) × 2 = 206
information-carrying bits. Modulation is 9-FSK: eight tones are used
for data, one for synchronization. Sixteen symbol intervals are
devoted to synchronization, so a transmission requires a total of 206
/ 3 + 16 = 85 (rounded up) channel symbols. The sync symbols are
those numbered 1, 2, 5, 10, 16, 23, 33, 35, 51, 52, 55, 60, 66, 73,
83, and 85 in the transmitted sequence.
for data, one for synchronization. Thus, three data bits or one
synchronization bit are conveyed by each transmitted symbol. Sixteen
symbol intervals are devoted to synchronization, so a transmission
requires a total of 206 / 3 + 16 = 85 (rounded up) channel
symbols. The sync symbols are those numbered 1, 2, 5, 10, 16, 23, 33,
35, 51, 52, 55, 60, 66, 73, 83, and 85 in the transmitted sequence.
Each symbol lasts for 6912 sample intervals at 12000 samples per
second, or about 0.576 s. Tone spacing of the 9-FSK modulation is
12000/6912 = 1.736 Hz, the inverse of the symbol duration. The total
occupied bandwidth is therefore 9 × 1.736 = 15.6 Hz. The generated
JT9 signal has continuous phase and constant amplitude. There are no
key clicks, and the transmitter's power amplifier need not be highly
linear.

minimal QSOs using short, formatted messages. The process works best

.Bandwidth and Frequency Setting
Taking full advantage of the wide-band, dual-mode capability of
{wsjtx} requires a receiver bandwidth of at least 4 kHz. For example,
on a Kenwood TS-2000 I set *Low Cut* to 200 and *High Cut* to 5000
Hz. Note that most SSB transceivers have a fixed Tx filter that will
not pass audio frequencies higher than about 2700 Hz. {wsjtx} takes
care of this by using Split mode, receiving with *VFO A* and
transmitting with *VFO B*. The Tx dial frequency (*VFO B*) is offset
in 500 Hz steps, and the generated audio frequency is adjusted so that
_WSJT-X_ requires a receiver bandwidth of at least 4 kHz. Many SSB
transceivers have a fixed-width Tx filter that will not pass audio
frequencies higher than about 2700 Hz. _WSJT-X_ takes care of this by
using Split mode, receiving with *VFO A* and transmitting with *VFO
B*. Under CAT control _WSJT-X_ offsets the Tx dial frequency (*VFO
B*) in 500 Hz steps, adjusting the generated audio frequency so that
it always falls in the range 1500 2000 Hz. With *CAT* and *Split Tx*
enabled on the configuration screen and your transceiver set to
*Tx Split* mode, frequency control will be handled automatically.
enabled on the configuration screen and your transceiver set to *Tx
