Updated the corresponding mouse shortcuts help text. Allow for times with seconds when parsing fast mode and FT8 decodes. Exclude the RR73 grid square from and grid validation or matching, it is not a grid square any more as far as WSJT-X is concerned, it is an RRR substitute. Add a simple state machine for QSO progress such that replies and auto-sequencing can be better controlled. Get compound callsign edge cases working again and allow QSOs from and to compound callsign holders working in as many situations as possible including auto-sequencing and FT8 auto-reply mode. This does mean that a "DE W6/K1ABC DM93" type message close to a callers Tx or Rx frequency will be taken as a reply to a CQ call despite it not being explicitly addressed back to the CQ caller. Compound callsigns should work in MSK144 contest mode also as well as in short code modes with some minor restrictions (short codes will not be used where configuration demands that a message be used to send a full compound callsign). Auto sequencing has been made generic such that it can be used for more than one mode if desired. Allow the use of free text messages to sign off in auto sequenced QSOs without the message being overwritten by the sequencer. Double click actions have been added to the Tx5 radio and push buttons to revert back to the default standard 73 message. Make DisplayText class interface more idiomatic C++ and simplify a bit. Fixed some displayed widget arrangements for different modes and sub-modes so that they are consistent when starting up and when switching mode or sub-mode. This is a big change which has been extensively tested but no doubt there will also be some new defects introduced. ------------------------------------------------------------------------ r7940 | bsomervi | 2017-07-25 17:51:19 +0100 (Tue, 25 Jul 2017) | 1 line Fix issue with Tx5 not being generated with a new DX Call ------------------------------------------------------------------------ r7941 | bsomervi | 2017-07-25 17:51:27 +0100 (Tue, 25 Jul 2017) | 1 line Fix country name display that broke in r7939 ------------------------------------------------------------------------ r7942 | bsomervi | 2017-07-25 17:51:34 +0100 (Tue, 25 Jul 2017) | 1 line Ensure JT9 lowest decode frequency spin box is disabled when not available ------------------------------------------------------------------------ r7943 | bsomervi | 2017-07-25 17:51:42 +0100 (Tue, 25 Jul 2017) | 4 lines Pick up tail-enders when completing a call 1st QSO after re-enabling auto Tx Allow any message to start a QSO so long as we are not in an auto-reply QSO. ------------------------------------------------------------------------ r7944 | bsomervi | 2017-07-25 17:51:49 +0100 (Tue, 25 Jul 2017) | 1 line Exclude all decode quality markers from internal decode parsing and matching ------------------------------------------------------------------------ r7945 | k9an | 2017-07-25 20:06:05 +0100 (Tue, 25 Jul 2017) | 1 line Move '?' quality warning to message(22:22). ------------------------------------------------------------------------ r7946 | k9an | 2017-07-25 21:55:13 +0100 (Tue, 25 Jul 2017) | 1 line Reject candiates with fewer than 7 correct hard-decoded sync symbols. ------------------------------------------------------------------------ r7947 | bsomervi | 2017-07-26 02:38:37 +0100 (Wed, 26 Jul 2017) | 1 line Force Settings tab to Radio tab when navigating there from a rig error message ------------------------------------------------------------------------ r7948 | bsomervi | 2017-07-26 02:38:44 +0100 (Wed, 26 Jul 2017) | 1 line Correct the highlighting of the Call 1st check box label ------------------------------------------------------------------------ r7949 | bsomervi | 2017-07-26 02:38:57 +0100 (Wed, 26 Jul 2017) | 5 lines Option to skip using grid reply message Enable and disable by double-clicking the Tx1 button or the adjacent radio button.

=== Standard Exchange
|
||
By longstanding tradition, a minimally valid QSO requires the exchange
|
||
of callsigns, a signal report or some other information, and
|
||
acknowledgments. _WSJT-X_ is designed to facilitate making such
|
||
minimal QSOs using short, structured messages. The process works best
|
||
if you use these formats and follow standard operating practices. The
|
||
recommended basic QSO goes something like this:
|
||
|
||
CQ K1ABC FN42 #K1ABC calls CQ
|
||
K1ABC G0XYZ IO91 #G0XYZ answers
|
||
G0XYZ K1ABC –19 #K1ABC sends report
|
||
K1ABC G0XYZ R-22 #G0XYZ sends R+report
|
||
G0XYZ K1ABC RRR #K1ABC sends RRR
|
||
K1ABC G0XYZ 73 #G0XYZ sends 73
|
||
|
||
*Standard messages* consist of two callsigns (or CQ, QRZ, or DE and
|
||
one callsign) followed by the transmitting station’s grid locator, a
|
||
signal report, R plus a signal report, or the final acknowledgements
|
||
RRR or 73. These messages are compressed and encoded in a highly
|
||
efficient and reliable way. In uncompressed form (as displayed
|
||
on-screen) they may contain as many as 22 characters.
|
||
|
||
*Signal reports* are specified as signal-to-noise ratio (S/N) in dB,
|
||
using a standard reference noise bandwidth of 2500 Hz. Thus, in the
|
||
example message above, K1ABC is telling G0XYZ that his
|
||
signal is 19 dB below the noise power in bandwidth 2500 Hz. In the
|
||
message at 0004, G0XYZ acknowledges receipt of that report and
|
||
responds with a –22 dB signal report. JT65 reports are constrained to
|
||
lie in the range –30 to –1 dB, and values are significantly compressed
|
||
above about -10 dB. JT9 supports the extended range –50 to +49 dB and
|
||
assigns more reliable numbers to relatively strong signals.
|
||
|
||
NOTE: Signals become visible on the waterfall around S/N = –26 dB
|
||
and audible (to someone with very good hearing) around –15
|
||
dB. Thresholds for decodability are around -23 dB for JT4, –24 dB for
|
||
JT65, –26 dB for JT9.
|
||
|
||
=== Free-Text Messages
|
||
|
||
Users often add some friendly chit-chat at the end of a QSO.
|
||
Free-format messages such as "`TNX ROBERT 73`" or "`5W VERT 73 GL`"
|
||
are supported, up to a maximum of 13 characters, including spaces. In
|
||
general you should avoid the character / in free-text messages, as the
|
||
program may then try to interpret your construction as part of a
|
||
compound callsign. It should be obvious that the JT4, JT9, and JT65
|
||
protocols are not designed or well suited for extensive conversations
|
||
or rag-chewing.
|
||
|
||
=== Auto-Sequencing
|
||
|
||
The slow modes JT4, JT9, JT65, and QRA64 allow nearly 10 seconds at
|
||
the end of each one-minute receiving sequence in which you can inspect
|
||
decoded messages and decide how to reply. With its 15-second T/R
|
||
cycles, FT8 allows only about two seconds for this task. For this
|
||
reason a basic auto-sequencing feature is offered. Check *Auto Seq*
|
||
on the main window to enable this feature:
|
||
|
||
image::auto-seq.png[align="center",alt="AutoSeq"]
|
||
|
||
When calling CQ you may also choose to check the box *Call 1st*.
|
||
_WSJT-X_ will then respond automatically to the first decoded
|
||
responder to your CQ.
|
||
|
||
TIP: When *Auto-Seq* is enabled the program will de-activate *Enable
|
||
Tx* at the end of each QSO. We do not want _WSJT-X_ to make fully
|
||
automated QSOs.
|
||
|
||
|
||
[[COMP-CALL]]
|
||
=== Compound Callsigns
|
||
|
||
Compound callsigns such as xx/K1ABC or K1ABC/x are handled in
|
||
one of two possible ways:
|
||
|
||
.Messages containing Type 1 compound callsigns
|
||
|
||
A list of about 350 of the most common prefixes and suffixes can be
|
||
displayed from the *Help* menu. A single compound callsign involving
|
||
one item from this list can be used in place of the standard third
|
||
word of a message (normally a locator, signal report, RRR, or 73).
|
||
The following examples are all acceptable messages containing *Type 1*
|
||
compound callsigns:
|
||
|
||
CQ ZA/K1ABC
|
||
CQ K1ABC/4
|
||
ZA/K1ABC G0XYZ
|
||
G0XYZ K1ABC/4
|
||
|
||
The following messages are _not_ valid, because a third word is not
|
||
permitted in any message containing a *Type 1* compound callsign:
|
||
|
||
ZA/K1ABC G0XYZ -22 #These messages are invalid; each would
|
||
G0XYZ K1ABC/4 73 # be sent without its third "word"
|
||
|
||
A QSO between two stations using *Type 1* compound-callsign messages
|
||
might look like this:
|
||
|
||
CQ ZA/K1ABC
|
||
ZA/K1ABC G0XYZ
|
||
G0XYZ K1ABC –19
|
||
K1ABC G0XYZ R–22
|
||
G0XYZ K1ABC RRR
|
||
K1ABC G0XYZ 73
|
||
|
||
Notice that the full compound callsign is sent and received in the
|
||
first two transmissions. After that, the operators omit the add-on
|
||
prefix or suffix and use the standard structured messages.
|
||
|
||
.Type 2 Compound-Callsign Messages
|
||
|
||
Prefixes and suffixes _not_ found in the displayable short list are
|
||
handled by using *Type 2* compound callsigns. In this case the
|
||
compound callsign must be the second word in a two- or three-word
|
||
message, and the first word must be CQ, DE, or QRZ. Prefixes can be 1
|
||
to 4 characters, suffixes 1 to 3 characters. A third word conveying a
|
||
locator, report, RRR, or 73 is permitted. The following are valid
|
||
messages containing *Type 2* compound callsigns:
|
||
|
||
CQ W4/G0XYZ FM07
|
||
QRZ K1ABC/VE6 DO33
|
||
DE W4/G0XYZ FM18
|
||
DE W4/G0XYZ -22
|
||
DE W4/G0XYZ R-22
|
||
DE W4/G0XYZ RRR
|
||
DE W4/G0XYZ 73
|
||
|
||
In each case, the compound callsign is treated as *Type 2* because the
|
||
add-on prefix or suffix is _not_ one of those in the fixed list. Note
|
||
that a second callsign is never permissible in these messages.
|
||
|
||
TIP: During a transmission your outgoing message is displayed in the
|
||
first label on the *Status Bar* and shown exactly as another station
|
||
will receive it. You can check to see that you are actually
|
||
transmitting the message you wish to send.
|
||
|
||
QSOs involving *Type 2* compound callsigns might look like either
|
||
of the following sequences:
|
||
|
||
CQ K1ABC/VE1 FN75
|
||
K1ABC G0XYZ IO91
|
||
G0XYZ K1ABC –19
|
||
K1ABC G0XYZ R–22
|
||
G0XYZ K1ABC RRR
|
||
K1ABC/VE1 73
|
||
|
||
|
||
CQ K1ABC FN42
|
||
DE G0XYZ/W4 FM18
|
||
G0XYZ K1ABC –19
|
||
K1ABC G0XYZ R–22
|
||
G0XYZ K1ABC RRR
|
||
DE G0XYZ/W4 73
|
||
|
||
Operators with a compound callsign use its full form when calling CQ
|
||
and possibly also in a 73 transmission, as may be required by
|
||
licensing authorities. Other transmissions during a QSO may use the
|
||
standard structured messages without callsign prefix or suffix.
|
||
|
||
TIP: If you are using a compound callsign, you may want to
|
||
experiment with the option *Message generation for type 2 compound
|
||
callsign holders* on the *Settings | General* tab, so that messages
|
||
will be generated that best suit your needs.

=== Pre-QSO Checklist
|
||
|
||
Before attempting your first QSO with one of the WSJT modes, be sure
|
||
to go through the <<TUTORIAL,Basic Operating Tutorial>> above as well
|
||
as the following checklist:
|
||
|
||
- Your callsign and grid locator set to correct values
|
||
|
||
- PTT and CAT control (if used) properly configured and tested
|
||
|
||
- Computer clock properly synchronized to UTC within ±1 s
|
||
|
||
- Radio set to *USB* (upper sideband) mode
|
||
|
||
- Radio filters centered and set to widest available passband (up to 5 kHz).
|
||
|
||
TIP: Remember that in many circumstances FT8, JT4, JT9, JT65, and WSPR
|
||
do not require high power. Under most HF propagation conditions, QRP
|
||
is usually the norm.
