It is possible to run two instances of WSJT-X simultaneously. See "Section 16.2
Frequently asked Questions" in the User Guide. If you wish to run more than two instances
simultaneously, the sysctl.conf file needs to be modified. Please email me with your
requirements and I will provide a replacement sysctl.conf to suit.
simultaneously, the shmall parameter in the sysctl.conf file needs to be modified as follows.
The shmall parameter determines the amount of shared memory which is allocated in 4096 byte pages
with 50MB (52428800) required for each instance. The shmall parameter is calculated as:
(n * 52428800)/4096 where 'n' is the number of instances required to run simultaneously. If
you are using an Intel Mac, modify the shmall parameter in the sysctl.conf file using a Mac editor
and then install in the /etc directory using the installation procedure described above for an
Intel Mac. Remember to reboot your Mac afterwards.
If you are using an M1 Mac, then simply issue the sudo sysctl -w kern.sysv.shmall=xxx command where
xxx is the new value of shmall that is required.
Note that the shmmax parameter remains unchanged. This is the maximum amount of shared memory that
any one instance is allowed to request from the total shared memory allocation and should not
be changed.
If two instances of WSJT-X are running, it is likely that you might need additional
audio devices, from two rigs for example. Visit Audio MIDI Setup and create an Aggregate Device
which will allow you to specific more than one interface. I recommend you consult Apple's guide
which will allow you to specify more than one interface. I recommend you consult Apple's guide
on combining multiple audio interfaces which is at https://support.apple.com/en-us/HT202000.

Release: WSJT-X 2.4.0-rc2
Mar 6, 2021
-------------------------
WSJT-X 2.4.0 Release Candidate 2 adds new Q65 mode functionality and
decoder optimizations; repairs defects and regressions discovered in
the RC1 release.
- Q65 sample .WAV files added.
- Repair a defect that caused WSJT-X to crash when launched from an
icon on macOS.
- Repair a crash when using the JT4 mode.
- Sequencing improvements to hold transmitted signal report fixed
during a QSO.
- UI translation updates tnx to Sze-to, VR2UPU, and Michael, 5P1KZX.
- Enable the "Call 1st" option for Q65.
- Improved Q65 message averaging that linearly averages the first 4
sequences and averages exponentially thereafter using a
time-constant of 4 sequences.
- Improved macOS post-install instructions, tnx to John, G4KLA.
- Enhanced Q65 simulator that generates file names compatible with
message averaging, tnx Charlie, G3WDG.
- Q65 simulator option to generate single tone waveforms, tnx to
Charlie, G3WDG.
- Better suppression of birdies in the Q65 decoder.
- Blank Q65 decode messages removed.
- Automatic low Tx audio offset for the widest Q65 modes to keep Tx
signal in transmitter passband, tnx to Charlie, G3WDG.
- Improved SNR estimates for Q65 mode.
- Decode depths Fast/Normal/Deep are now identical in Q65 mode.
- "Save decoded" is now enabled for Q65 mode.
- The obsolete ISCAT mode has been removed.
Release: WSJT-X 2.3.1
Mar 8, 2021
---------------------
WSJT-X 2.3.1 General Availability release updates the User Guide to
cover the new modes FST4 and FST4W along with sample .WAV files and
decoding tutorials. This release also repairs a number of defects and
regressions discovered since the v2.3.0 release, including those
below.
- When sending traffic to a multicast UDP server ensure that the
local loop-back interface is used if no others are selected.
- Repair a defect in instance lock file handling that causes an
infinite loop on start up.
- Invert the PTT serial port sharing default behaviour, and enable
sharing when non-Hamlib CAT control is combined with direct serial
port PTT control.
- Allow the FST4 and FST4W decoders to continue after the first
successful decode when using negative NB values to try multiple NB
values.
- Repair defects in auto-sequencing, particularly with responding to
a repeated final message. In general a double-click of the repeated
message now does the right thing.
- Repair a regression that had inadvertently disabled EU VHF Contest
mode when using the MSK144 mode.
- Repair a defect that could caused incorrect log entry fields when
using FT4 mode and a priori (AP) decoding.

first seven are designed for making reliable QSOs under 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 some advantages over
JT65, including better performance for EME on the higher microwave
bands. JT9 was originally designed for the HF and lower bands. Its
submode JT9A is 1 dB more sensitive than JT65 while using less than
10% of the bandwidth. JT4 offers a wide variety of tone spacings and
has proven highly effective for EME on microwave bands up to 24 GHz.
These four "`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. FT8 is operationally similar
but four times faster (15-second T/R sequences) and less sensitive by
a few dB. FT4 is faster still (7.5 s T/R sequences) and especially
well-suited for radio contesting. FST4 was added to _WSJT-X_ in
version 2.3.0. It is intended especially for use on the LF and MF
bands, and already during its first few months of testing

[[NEW_FEATURES]]
=== New in Version {VERSION}
_WSJT-X 2.3.0_ introduces *FST4* and *FST4W*, new digital protocols
designed particularly for the LF and MF bands. Decoders for these
modes can take advantage of the very small Doppler spreads present at
these frequencies, even over intercontinental distances. As a
consequence, fundamental sensitivities of FST4 and FST4W are better
than other _WSJT-X_ modes with the same sequence lengths, approaching
the theoretical limits for their rates of information throughput. The
FST4 protocol is optimized for two-way QSOs, while FST4W is for
quasi-beacon transmissions of WSPR-style messages. FST4 and FST4W do
not require the strict, independent phase locking and time
synchronization of modes like EbNaut.
_WSJT-X 2.4.0_ introduces *Q65*, a new digital protocol designed for
minimal two-way QSOs over especially difficult propagation paths. On
paths with Doppler spread more than a few Hz, the weak-signal
performance of Q65 is the best among all WSJT-X modes.
The new modes use 4-GFSK modulation and share common software for
encoding and decoding messages. FST4 offers T/R sequence lengths of
15, 30, 60, 120, 300, 900, and 1800 seconds, while FST4W omits the
lengths shorter than 120 s. Submodes are given names like FST4-60,
FST4W-300, etc., the appended numbers indicating sequence length in
seconds. Message payloads contain either 77 bits, as in FT4, FT8, and
MSK144, or 50 bits for the WSPR-like messages of FST4W. Message
formats displayed to the user are like those in the other 77-bit and
50-bit modes in _WSJT-X_. Forward error correction uses a low density
parity check (LDPC) code with 240 information and parity bits.
Transmissions consist of 160 symbols: 120 information-carrying symbols
of two bits each, interspersed with five groups of eight predefined
synchronization symbols.
*We recommend that on the 2200 and 630 m bands FST4 should replace JT9
for making 2-way QSOs, and FST4W should replace WSPR for propagation
tests*. Operating conventions on these LF and MF bands will
eventually determine the most useful T/R sequence lengths for each
type of operation.
Q65 uses message formats and sequencing identical to those used in
FST4, FT4, FT8, and MSK144. Submodes are provided with a wide variety
of tone spacings and T/R sequence lengths 15, 30, 60, 120, and 300 s.
A new, highly reliable list-decoding technique is used for messages
that contain previously copied message fragments. Message averaging
is provided for situations where single transmissions are too weak or
signal enhancements too sparse for a signal to be decoded.

[[QRA64_PROTOCOL]]
==== QRA64
[[Q65_PROTOCOL]]
==== Q65
QRA64 is intended for EME and other extreme weak-signal applications.
Its internal code was designed by IV3NWV. The protocol uses a (63,12)
**Q**-ary **R**epeat **A**ccumulate code that is inherently better
than the Reed Solomon (63,12) code used in JT65, yielding a 1.3 dB
advantage. A new synchronizing scheme is based on three 7 x 7 Costas
arrays. This change yields another 1.9 dB advantage.
Q65 is intended for scatter, EME, and other extreme weak-signal
applications. Forward error correction (FEC) uses a specially
designed (65,15) block code with six-bit symbols. Two symbols are
“punctured” from the code, yielding an effective (63,13) code with a
payload of k = 13 information symbols conveyed by n = 63 channel
symbols. The punctured symbols consist of a 12-bit CRC computed from
the 13 information symbols. The CRC is used to reduce the
false-decode rate to a very low value. A 22-symbol pseudo-random
sequence spread throughout a transmission is sent as “tone 0” and used
for synchronization. The total number of channel symbols in a Q65
transmission is thus 63 + 22 = 85.
In most respects the current implementation of QRA64 is operationally
similar to JT65. QRA64 does not use two-tone shorthand messages, and
it makes no use of a callsign database. Rather, additional
sensitivity is gained by making use of already known information as a
QSO progresses -- for example, when reports are being exchanged and
you have already decoded both callsigns in a previous transmission.
QRA64 presently offers no message averaging capability, though that
feature may be added. In early tests, many EME QSOs were made using
submodes QRA64A-E on bands from 144 MHz to 24 GHz.
For each T/R sequence length, submodes A - E have tone spacings and
occupied bandwidths 1, 2, 4, 8, and 16 times those specified in the
above table. Full submode designations include a number for sequence
length and a letter for tone spacing, as in Q65-15A, Q65-120C, etc.

==== ISCAT
ISCAT messages are free-form, up to 28 characters in length.
Modulation is 42-tone frequency-shift keying at 11025 / 512 = 21.533
baud (ISCAT-A), or 11025 / 256 = 43.066 baud (ISCAT-B). Tone
frequencies are spaced by an amount in Hz equal to the baud rate. The
available character set is:
----
0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ /.?@-
----
Transmissions consist of sequences of 24 symbols: a synchronizing
pattern of four symbols at tone numbers 0, 1, 3, and 2, followed by
two symbols with tone number corresponding to (message length) and
(message length + 5), and, finally, 18 symbols conveying the user's
message, sent repeatedly character by character. The message always
starts with `@`, the beginning-of-message symbol, which is not
displayed to the user. The sync pattern and message-length indicator
have a fixed repetition period, recurring every 24 symbols. Message
information occurs periodically within the 18 symbol positions set
aside for its use, repeating at its own natural length.
For example, consider the user message `CQ WA9XYZ`. Including the
beginning-of-message symbol `@`, the message is 10 characters long.
Using the character sequence displayed above to indicate tone numbers,
the transmitted message will therefore start out as shown in the first
line below:
----

Note that the first six symbols (four for sync, two for message
length) repeat every 24 symbols. Within the 18 information-carrying
symbols in each 24, the user message `@CQ WA9XYZ` repeats at its own
natural length, 10 characters. The resulting sequence is extended as

FST4 is designed primarily for making weak-signal 2-way QSOs on the
LF and MF bands. T/R periods from 15 s up to 1800 s are
available. Longer T/R periods provide better sensitivity only if
Tx and Rx frequency instability and channel Doppler spread
are small enough so that received signals
remain phase coherent over periods spanning several transmitted symbols.

to the symbol keying rate shown for each T/R duration in Table 7 within section

A noise blanker can be enabled by setting the *NB* percentage to a non-zero value.
This setting determines how many of the largest-amplitude samples will be
blanked (zeroed) before the data is submitted to the decoder. Most users find
that settings between 0% (no blanking) and 10% work best. If the noise
blanker percentage is set to -1%, then the decoder will try 0, 5, 10, 15, and 20 %
in succession. Similarly, a setting of -2% causes the decoder to loop over
blanking percentages 0, 2, 4, ... 20 %. To save time, the multiple blanking
percentages triggered by negative *NB* settings are tried only for signal
candidates located near (within +/- 20 Hz) of the *Rx* frequency setting.

=== QRA64
=== Q65
QRA64 is designed for EME on VHF and higher bands; its
operation is generally similar to JT4 and JT65. The following screen
shot shows an example of a QRA64C transmission from DL7YC recorded at
G3WDG over the EME path at 24 GHz. Doppler spread on the path was 78
Hz, so although the signal is reasonably strong its tones are
broadened enough to make them hard to see on the waterfall. The
triangular red marker below the frequency scale shows that the decoder
has achieved synchronization with a signal at approximately 967 Hz.
Q65 is designed for propagation paths that produce fast fading
signals: tropospheric scatter, rain scatter, ionospheric scatter,
trans-equatorial propagation (TEP), EME, and the like. The following
screen shot shows an example with submode Q65-30A on a 6-meter
ionospheric scatter path of about 1100 km.

The Q65 decoder makes no use of a callsign database. Instead, it
takes advantage of _a priori_ (AP) information such as one's own
callsign and the encoded form of message word `CQ`. In normal usage,
as a QSO progresses the available AP information increases to include
the callsign of the station being worked and perhaps also his/her
4-digit grid locator. The decoder always begins by attempting to
decode the full message using no AP information. If this attempt
fails, additional attempts are made using available AP information to
provide initial hypotheses about the message content. At the end of
each iteration the decoder computes the extrinsic probability of the
most likely value for each of the message's 12 six-bit information
symbols. A decode is declared only when the total probability for all
12 symbols has converged to an unambiguous value very close to 1.

progresses the available AP information increases to include the
callsign of the station being worked and perhaps also his/her 4-digit
grid locator. The decoder takes advantage of whatever AP information
is available.
For EME QSOs some operators use short-form QRA64 messages consisting
of a single tone. To activate automatic generation of these messages,
check the box labeled *Sh*. This also enables the generation of a
single tone at 1000Hz by selecting Tx6, to assist in finding signals
initially, as the QRA64 tones are often not visible on the waterfall.
The box labeled *Tx6* switches the Tx6 message from 1000Hz to 1250Hz
to indicate to the other station that you are ready to receive messages.

TIP: QRA64 attempts to find and decode only a single signal in the
receiver passband. If many signals are present, you may be able to
decode them by double-clicking on the lowest tone of each one in the
waterfall.
TIP: G3WDG has prepared a more detailed tutorial on using {QRA64_EME}.
=== ISCAT
ISCAT is a useful mode for signals that are weak but more or less
steady in amplitude over several seconds or longer. Aircraft scatter
at 10 GHz is a good example. ISCAT messages are free-format and may
have any length from 1 to 28 characters. This protocol includes no
error-correction facility.

Until the advent of Q65, digital EME has mostly been done using JT65A
on the 50 MHz band, JT65B on 144 and 432 MHz, and JT65C on 1296 MHz.
On higher microwave bands typical choices have been JT65C or one of
the wider QRA64 or JT4 submodes, depending on the expected amount of
Doppler spread. JT4 and JT65 offer message *Averaging* -- the
summation of subsequent transmissions that convey the same message --
to enable decodes at signal-to-noise ratios several dB below the
threshold for single transmissions. These modes also allow *Deep
Search* decoding, in which the decoder hypothesizes messages
containing known or previously decoded callsigns and tests them for
reliability using a correlation algorithm. Finally, JT65 and QRA64
offer _a priori_ (AP) decoding, which takes advantage of naturally
accumulating information during a QSO. The following tutorial aims to
familiarize you with these program features, all of which are of
special interest for EME and other extreme weak-signal conditions.

The code used by the QRA64 mode is the code: QRA13_64_64_IRR_E: K=13
N=64 Q=64 irregular QRA code (defined in qra13_64_64_irr_e.{h,c}).
This code has been designed to include a CRC as the 13th information
symbol and improve the code UER (Undetected Error Rate). The CRC
symbol is not sent along the channel (the codes are punctured) and the
resulting code is still a (12,63) code with an effective code rate of
R = 12/63.

Here we simulate the following (dummy) QSO:
1) CQ IV3NWV
2) IV3NWV K1JT
3) K1JT IV3NWV 73
4) IV3NWV K1JT 73
No message repetition is attempted
The QSO is counted as successfull if IV3NWV received the last message
When mode=QRA_AUTOAP each decoder attempts to decode the message sent
by the other station using the a-priori information derived by what
has been already decoded in a previous phase of the QSO if decoding
with no a-priori information has not been successful.
Step 1) K1JT's decoder first attempts to decode msgs of type [? ? ?]
and if this attempt fails, it attempts to decode [CQ/QRZ ? ?] or
[CQ/QRZ ?] msgs
Step 2) if IV3NWV's decoder is unable to decode K1JT's without AP it
attempts to decode messages of the type [IV3NWV ? ?] and [IV3NWV ?].
Step 3) K1JT's decoder attempts to decode [? ? ?] and [K1JT IV3NWV ?]
(this last decode type has been enabled by K1JT's encoder at step 2)
Step 4) IV3NWV's decoder attempts to decode [? ? ?] and [IV3NWV K1JT
?] (this last decode type has been enabled by IV3NWV's encoder at step
3)
At each step the simulation reports if a decode was successful. In
this case it also reports the type of decode (see table decode_type
above)
When mode=QRA_NOAP, only [? ? ?] decodes are attempted and no a-priori
information is used by the decoder
The function returns 0 if all of the four messages have been decoded
by their recipients (with no retries) and -1 if any of them could not
be decoded

Here we simulate the decoder of K1JT after K1JT has sent a msg [IV3NWV K1JT]

If mode=QRA_NOAP, K1JT decoder attempts to decode only msgs of type [? ? ?].
If mode=QRA_AUTOP, K1JT decoder will attempt to decode also the msgs
[K1JT IV3NWV] and [K1JT IV3NWV ?].
In the case a decode is successful the return code of the qra64_decode function
indicates the amount of a-priori information required to decode the received
message according to this table:
rc=0 [? ? ?] AP0
rc=1 [CQ ? ?] AP27
rc=2 [CQ ? ] AP42
rc=3 [CALL ? ?] AP29

rc=7 [? CALL ] AP44
rc=8 [CALL CALL GRID] AP72
rc=9 [CQ CALL ?] AP55
rc=10 [CQ CALL ] AP70
rc=11 [CQ CALL GRID] AP70
The return code is <0 when decoding is unsuccessful
This test simulates the situation ntx times and reports how many times
a particular type decode among the above 6 cases succeded.

QRA64 Mode Tests
2016, Nico Palermo - IV3NWV
---------------------------
Syntax: qra64 [-s<snrdb>] [-c<channel>] [-a<ap-type>] [-t<testtype>] [-h]
Options:
-s<snrdb> : set simulation SNR in 2500 Hz BW (default:-27.5 dB)
-c<channel> : set channel type 0=AWGN (default) 1=Rayleigh
-a<ap-type> : set decode type 0=NOAP 1=AUTOAP (default) 2=USERAP
-t<testtype>: 0=simulate seq of msgs between IV3NWV and K1JT (default)
1=simulate K1JT receiving K1JT IV3NWV JN66
2=simulate fast-fading routines (option -c ignored)
Options used only for fast-fading simulations:
-b : 90% fading bandwidth in Hz [1..230 Hz] (default = 2.5 Hz)
-m : fading model. 0=Gauss, 1=Lorentz (default = Lorentz)
-q : qra64 submode. 0=QRA64A,... 4=QRA64E (default = QRA64A)
-h: this help
#############################################################################
Usage example:
qra64 -c2 -t2 -a2 -b50 -m1 -q2 -s-26.0 -n50000
Simulate a fast-fading channel (-c2)
Evaluate decoder performance (-t2) with
USER_AP (-a2)
B90 = 50 Hz (-b50)
Lorentz model (-m1)
submode QRA64C (-q2)
Input SNR = -26.0 dB (-s-26.0)
Simulate 50000 transmissions (-n50000)
(type qra64 -h for command syntax)
Command Output:
Input SNR = -26.0dB ap-mode=USER AP
Simulating the fast-fading channel
B90=50.00 Hz - Fading Model=Lorentz - Submode=QRA64C
