Any new callsign from DX Call window once associated with the hash in the decoded message will substitute previous callsign in the hash table if both have the same hash value.
        - hash table shall be stored into hashtable1.txt file(log directory) with every new callsign recognized from the special DXpedition message
        - JTDX shall read a data from hashtable1.txt file and put it into hash table upon first start of decoder
        - active Hound mode will be switched off if user changed band to the regular band
        - callsign shall be cleared from QSO history if user triggered QSO by double click on decoded message with SkipTx1 option enabled

        - Hound mode can be enabled in DXpedition tab of the main window UI
        - Hound button is added into main window UI to duplicate Hound mode action in DXpedition tab
        - AutoTx button will be switched on if Hound mode is activated

        - in case of DXpedition QSO failure after three transmissions of the 'R+REPORT' message, frequency control will set TX AF frequency back to the initial value
        - Hound TX frequency control is not allowed for usage in common FT8 bands (with exception to the 60m band) or if Split Fake It|Rig is switched off, warning message will be triggered in such scenarios. 3 KHz delta frequency is set as guard interval to common FT8 bands.


        - Hamlib is modified to let getting output power level from some ICOM transceivers via CAT, IC7000/7100/7300 models tested.

      • Changelog 27th July (

        - Ham Radio Deluxe CAT control is brought to the latest WSJT-X implementation
        - more criteria implemented to check for the false decodes: all messages with SNR -23dB or delta time less than -0.5 or greater than 2.0 sec shall be checked
        - filtering out false FT8AP(Hint) decodes where user's callsign is erroneously decoded as the compound callsign
        - more masks are added to filter falsely decoded free text messages
        - minor patch to FT8 decoder: logarithmic function shall not get zero argument
        - minor patch to pskreporter spotting functionality
        - added support to special DXpedition dual message decoding, a message transmitted under the 75-bit protocol.
        Decoded special message will only be displayed if callsign it is originated from is located in the DX Call window.
        Since callsign hash is being used for special message transmission there is no other way to recognize who transmitted the message but keeping the callsign in the DX Call window.
        Special message will not be displayed if DX Call window is empty or if there is other callsign in the window.
        Decoded special message will be displayed as two standard messages where there is no notification that callsign is matched to the received hash rather than decoded,
        that is different to WSJT-X approach:

        AA1AAA RR73; BB1BBB -05

        AA1AAA CC1CCC RR73
        BB1BBB CC1CCC -05

        - patches to allow AutoSeq handle multiple WSJT-X Fox DXpedition and MSHV 'Multianswering Auto Seq protocol FT8' messages
        - patch to the QSO start date/time format in wsjtx.log file
        - patch to the Halt Tx AutoSeq functionality at end of QSO
        - transmitted message counters are implemented with option to either call CQ or Halt Tx, counters can be activated and configured in the 'Sequencing' tab of the settings
        - improved wanted callsign functionality. Upon decoding a message with the wanted call there will be done report extraction, generation of standard messages, selection of the proper TX period. Wanted call window will be cleaned up if wanted callsign is logged.
        - wanted callsign list is implemented instead of the single callsign, where callsigns shall be separated by the comma. For compound callsigns the base callsign shall be used in the list. If DX Call window is empty and user is not transmitting then upon first wanted decoding in the period audio alert will be generated, decoded callsign will be copied in DX Call window and standard messages will be generated. Some messages contain only base part of the compound callsign, hence base callsign will be copied from such decoded message to DX Call window: when logging such QSO user will have to change correspondent's base callsign to compound one if needed.
        - serialized callback(decoded messages to stdout) in FT8 decoder
        - changed names of the rigctl rigctld utilities
        - cursor position shall be stored in the wanted callsign, hide country, hide callsign, content filter, DX Call, DX Grid, CQ Direction line edit windows, main window and Configuration UI
        - defect fixed where manual clicking on Decode button could brake AutoSeq operation(wrong message transmission) and trigger Halt Tx: AutoSeq and Halt Tx shall not be processed if user clicked on the Decode button or twice clicked on the waterfall.
        - tooltip to DisTx73 button shall clearly say that state of this button is ignored under AutoSeq operation
        - message radio button if selected by user under AutoSeq can brake AutoSeq operation, all radio buttons in Tab1 shall be disabled if AutoSeq button is switched on. Changed appearance of disabled selected TX radio button in tab1.
        - Halt Tx reason is added for recording to ALL.TXT file for diagnostic purpose
        - all message fields in Tab1 will be cleaned up if Tx6 (CQ message) button is clicked by user
        - patch to let AutoSeq handle DE message from compound callsigns
        - default 60m FT8 frequency for 60m band is changed to 5357kHz, RESET button in the Frequencies tab of the settings shall once be used to update this frequency
        - changed MAC OSX bundle GUI ID to org.jtdx
        - 'CQ DE CALL' 'QRZ DE CALL' messages shall not be treated as directional CQ
        - 'DE' is not allowed as CQ direction in the direction line edit widgets
        - AutoSeq button shall get the pink color if it is switched off in FT8 mode
        - AutoSeq shall process transmitted free text message if it is equal in any of four possible parts to any of this words: 73, TNX, TKS, TU.
        - AutoSeq button now shall be switched off automatically at beginning of the free text message transmission if this message does not comply with AutoSeq. Both Tab1 and Tab2 free text message evaluation is supported. AutoSeq will not process other transmitted free text messages and AutoSeq button will be switched off upon attempt of such transmission. AutoSeq button will be automatically switched back on upon generation of the standard messages in Tab1 and Tab2 or if Tx6 (CQ) button is clicked in Tab1(in Tab2 any message button generates standard message).
        - patch to SkipGRID/Skip Tx1 functionality
        - patch to AutoSeq sequence: 'received RR73-> sent 73 -> received RR73 ->QSO finished' shall be processed as 'received RR73 -> sent 73 -> received RR73 -> sent 73'
        - cty.dat file is updated to the version CTY-2809
        - updated ALLCALL.TXT file, now containing 67332 callsigns

        Known unresolved issues:
        - PTT over CAT delay at start of JTDX or after the band/frequency change if HRD or DXLab Commander CAT is being used.
        Possible workaround: PTT over DTR/RTS signal of the serial port instead of PTT command via CAT.
        - some DXpedition Fox messages are being not decoded correctly.

        JTDX.INI file structure is changed, deleted setting "WantedCall","SeqBackToCqMsg","SeqRetransmitMsg","SeqHaltTxSameMsgRprt","SeqHaltTxSameMsg73",

        added new settings: "WantedCallCommaList","SeqAnswerCQCount","SeqAnswerInCallCount","SeqSentRReportCount","SeqSentRR7373Count",

New option 'Hide FT8 dupe messages' is implemented and can be controlled via Misc tab of mainwindow UI. It is better to hide dupe messages at on air operation as AutoSeq picking up last decoded message and if SNR has less value than for previous message then AutoSeq will get wrong QSO AF RX frequency. Such dupe messages are usually caused by dirty signals and reflection from aircraft. By default 'Hide FT8 dupe messages' option is enabled.
        - hide continent filter shall work now with AutoSeq
        - hide country filter is implemented, can be activated and set in Filter tab of the settings as a list of prefixes in comma separated format. Tooltip will show list of the prefixes. Messages containing user's callsign bypass this filter. Gaps are not allowed in the list. This filter is working with AutoSeq.
        - hide callsign filter is implemented, can be activated and set in Filter tab of the settings as a list of callsigns in comma separated format.
        Base callsign shall be used in the list for compound callsigns, gaps are not allowed in the list. User can add callsign into the 'Hide messages from callsigns' filter list by right mouse's button click on the DX Call button. This filter is working with AutoSeq. Messages containing user's callsign bypass this filter.
        - ALL.TXT file is being named now per month basis with 'yyyyMM_ALL.TXT' format. 'Erase ALL.TXT' action in the 'File' tab will delete last created ALL.TXT file.

      • Changelog 15th April (
        - added one more setting to FT8 decoder sensitivity action group: 'minimum', it will let user to switch off either 'use low thresholds' or 'use subpass' functionality

      • Changelog 14th April (
        - decoding subpass is introduced, raising up FT8 decoder sensitivity. It can be controlled via mainwindow UI 'Decode' tab -> FT8 decoding -> decoder sensitivity -> use subpass. This functionality requires usage of the low thresholds, hence both settings are combined into one action group: user can select either 'use low thresholds' or 'use subpass'. If 'use subpass' is selected then 'use low thresholds' flag is also being passed to the decoder.

        - updated ALLCALL.TXT file, containing 58485 callsigns
        - CAT Serial port configuration in the Radio tab of settings got an possibility to use default Hamlib settings for specific TRX model. This change is based on WSJT-X r8568 patch.
        - JTDX v18.1.0.82 installation package is built with the latest version of Hamlib

        Subpass functionality requires fast CPU, or can be used together with the SWL mode.
        JTDX.INI structure is changed, added settings to JTDX.INI: "UseFT8subpass"
        It should be safe to use JTDX.INI file from v18.1.0.81.
        There is changed number of serial port settings, transition from v18.1.0.82 to any previous version may cause some failures, it is better to use different INI file for old JTDX versions if there is any one being started after v18.1.0.82.

      • Changelog 20th March (

        - AGCc functionality is implemented to FT8, the same rule as for JT modes operation shall be applied by user: switch on AGCc button if AGC is being triggered in receiver by FT8 signals, otherwise please keep AGCc button switched off to preserve decoder sensitivity.
        FT8 AGCc functionality deals with the noise step at end of signal reception, this noise step disturbs decoder synchronization to the received signals.

        - minor changes in Notifications tab of Configuration UI: 'per mode' have been independent functionaltiy from 'per band', name and tooltips updated accordingly

        - 'Single shot QSO' (1 QSO) and 'Answer worked B4 calls' (AnsB4) dynamic buttons are implemented in mainwindow UI, will appear/disappear there depending on the vertical size of UI window. Both buttons just duplicate action controls located in the AutoSeq tab.

        - increased decoding efficiency of FT8 decoder

        - option of low thresholds usage into FT8 decoder is implemented, this option is dedicated to fast CPUs and gains decoding efficiency and improves sensitivity of FT8 decoder. More signal-candidates being processed, hence fast CPU is required to fit into end of RX interval before beginning of signal transmission. Low thresholds will be applied to SWL mode with no respect to the selected setting. This option is available via 'Decode -> FT8 decoding -> use low thresholds' action.

      • Changelog 7th March (

        6. Patch to let proper handling of the 'my call in message' notification red marker
        7. Blacklist functionality is implemented to AutoSeq mode, being used in both, auto sequencing and auto selection.

        Blacklist functionality is dedicated to prevent cyclic AutoSeq response to incoming call if calling operator left his setup unattended.
        Also user can use blacklist to prevent selection of CQ message and answering to it if there were several unsuccessful attempts before to answer to CQ message of this operator.

        User can add a callsign from DX Call window to the blacklist with CTRL+ mouse's right button click on Clear DX button, this will also clean up DX Call DX Grid windows and this callsign from QSO history.

        User can remove callsign located in DX Call window from blacklist using mouse's right button click on Clear DX button, this will also clean up DX Call DX Grid windows and this callsign from QSO history.

        All data in the blacklist will be automatically cleaned up at band change, configuration change and restart of JTDX.

      • Changelog 4th March (

        - SNR is calibrated at low levels to get into 1dB accuracy at -21..-22 dB levels, SNR reporting is limited to -22 dB as FT8 decoders can not pick up signals below -22dB SNR
        - 'TX messages to RX frequency window' option is brought back, this option is being used for content focused messages operation
        - Tx messages now will be displayed in RX frequency window if AutoSeq button is switched ON, it is required for auto sequence functionality operation.

    • Changelog 6th January
      - AutoSeq patch to prevent unexpected stopping TX if RR73 message is being used for transmission while QSO is not finished (message 73 is not received from QSO party operator)
      - color background for TX messages is aligned
      - AutoSeq patch to this scenario where directional CQ was used:

      20180105_035400 -4 -0.2 2140 ~ AG2T CM2RSV EL83
      20180105_035415 Transmitting 7.074 MHz FT8: CM2RSV AG2T -04
      20180105_035430 0 -0.2 2140 ~ AG2T CM2RSV EL83
      user disabled TX at 035445 035515 035545
      directional CQ message is generated and transmitted by user:
      20180105_035615 Transmitting 7.074 MHz FT8: CQ DX AG2T FN30
      unexpected RR73 message is triggered by AutoSeq:
      20180105_035615 Transmitting 7.074 MHz FT8: CM2RSV AG2T RR73
      20180105_035630 1 -0.1 2141 ~ AG2T CM2RSV RRR
      20180105_035645 Transmitting 7.074 MHz FT8: CM2RSV AG2T 73

    • Changelog 4th January
      - Patch applied to AutoSeq handling possible gaps in the incoming audio stream: AutoSeq shall not change during the QSO style of operation(message sequence) from 'calling CQ' to 'answering to CQ'. In addition to the previously described reasons of audio gaps there is scenario where user has single audio device that is set as default one by MS Windows operating system and user doing Web browsing during the QSO.
      - Minor SWL functionality is implemented to FT8 mode, raises FT8 decoding efficiency approximately 1% up, SWL functionality is not dedicated for on air operation
      - Text is set to blue color on the AutoSeq button if 'Single shot QSO' option is activated
      - No TX audio issue: there are two possible reasons,
      -- first is where user accepting Settings change dialog with OK button, patch is applied to this issue in scenario where there is no audio device changed
      -- second reason is that between consecutive pushing of buttons Halt Tx and Enable TX at message transmission shall be at least 2 second gap, if user does it faster it resulting in no TX audio in this TX interval. So far I don't know how to deal with this scenario.
      - New functionality for audio device change during message transmission: transmission will be stopped, Enable TX button will get yellow colr for couple seconds and message transmission will be restarted
      - Last logged callsign label is implemented in the status bar
      - Several errors fixed in the code, input signal array handling is changed at entry point of the FT8 decoder

    • Changelog 3rd January
      There is 'Single shot QSO' option implemented to let users switch off Enable Tx button automatically when QSO is finished.
      This functionality can be activated in the AutoSeq action list in main window UI.

    • Changelog 31th December

      - bug is fixed where SW did QSO in semi-automatic way while AutoSeq button was switched off
      - QSO party's callsign is being cleaned up from QSO history at 'hisCall myCall grid' message transmission

      Both changes can eliminate some wrong QSO sequences in AutoSeq mode.

    • Changelog 30th December

      AutoSeq wrong handling of received RR73 message is fixed
      Some more tweaks done to prevent unexpected AutoSeq transmissions on the frequency of ex- QSO party
      Bug is fixed in AutoSeq mode selection logic
      SWL mode is blocked in FT8 decoder to prevent it's unintended usage
      Band scheduler functionality is recovered
      Recovered passing DX Call decoded 73 message to RX frequency window in scenario where Enable Tx is switched off
      Fixed bug for "reading wav file" event and added Filter ON/OFF event into ALL.TXT
      Deleted JTDX version number from widegraph window title, as it caused compatibility issue with JTAlert software
      Added "QRZ " as trigger for AutoSeq
      Implemented new AutoFilter functionality for AutoSeq, it is dedicated for slow CPUs and may be used in AutoSeq 1,2,3 modes
      AutoFilter can be activated in the AutoSeq action list of main window UI

      Known unresolved issues:

      Enable Tx button is switched off after QSO in calling CQ operation and early QSO logging using "Prompt me to log QSO" scenario
      Free messages / TX macros functionality is partially broken
      AutoSeq can fail while handling compound callsigns
      AutoSeq can fail if called operator changed his TX frequency and has answered on some other frequency (?)

      Decoder latency, AutoSeq design and CPU processing speed related issue:
      Late interval decoding by CPU. AutoFilter functionality is implemented as workaround for this issue.

      JTDX.INI structure is changed, added new parameter "AutoFilter". JTDX.INI file from v18.1.0.58 can be used and shall not trigger any issues

    • Changelog 28th December

      Common version number being used for all UI windows and pskreporter,

      Now fixed unexpected RX frequency jumps from selected RX frequency to TX frequency if Enable TX button is turned off
      AutoSeq operation mode is named from 1 to 7, where 'and search CQ' is being used as 4 + any basic AutoSec number
      logging mode is being indicated as coloured background of QSO counter label (status bar)
      direction of CQ is being propagated to tx6 button (tab 1) on program initialization
      tooltips changed for Clear DX / Erase / Filter buttons and 'Halt Tx if operator I called answered to other operator' checkbox
      AutoSeq2 is set as default option
      changed functionality for Erase button: left mouse button will clean up left window, right mouse button will clean up right window, any mouse button double click will clean up both windows
      Currently unused Sequencing tab controls are disabled and greyed out

      Known issues:
      free messages / TX macros functionality is partially broken
      AutoSeq can fail while handling compound callsigns
      AutoSeq can fail if called operator changed his TX frequency

    • Changelog 25th December (compact and not all changes are shown)

      In answering to CQ operation and 'Prompt me to log QSO' logging mode:
      Enable TX button will always be switched off after QSO if TX frequency is equal to RX frequency
      Enable TX button will be switched off if TX frequency is not equal to RX frequency and user has accepted QSO logging when QSO is finished (73 message is received)
      Enable TX button will not be switched off if TX frequency is not equal to RX frequency and user has accepted QSO logging until QSO is finished (73 message is received), in this scenario after QSO JTDX will move RX frequency to TX frequency and will start calling CQ on the TX frequency

    • Changelog 23th December (compact and not all changes are shown)

      AutoSeq is always using priority, if there is any 'new one' criterion is set in Notifications tab then AutoSeq will be ignoring B4 calls and manual intervention will be required to answer it.
      There have been many changes, and selection changes can be seen in Mainwindow UI top tab under Sequencing.
      Any push buttons that are greyed are currently disabled for mode and or this step.

    • Changelog: 22th December

      Tx watchdog operation, now a double click on decoded line will trigger watchdog timer reset
      Default setting is now Call 1st
      If you experience any delay in decoding on busy bands, please use Call 1st
      Please copy a section of your all.txt file and post this privately or in group if you experience and issues.

    • Changelog 21th December (compact and not all changes are shown)

      AutoSeq Call 1st option is implemented, dedicated for usage on slow processors
      Skip TX1 functionality is supported now, sending report first
      FT8 wrong SNR reporting under Filter is fixed
      Directional CQ generation is changed in tab2
      Changed date/time format in ALL.TXT file to "yyyymmdd_hhmmss"
      Directional CQ, this allows user to input preferred calling area, and replaced CQ DX option in Tab 2

      Some features that use previous calls for priority may use more processing power, as it is performing more tasks; this is dependent on the station preferences in configuration filtering and Dx call, wanted call and worked B4 station in filters and notifications tab.

    • Changelog: 19th December

      Patch applied by Arvo for free text messages under Autoseq control
      Also the version number for PSK Reporter is now 18.1

      There have been many changes and additions these are a compact description.
      Action call priority and CQ
      This feature now will auto call stations in a sequence that have not already logged, allowing those stations who seek new call only to do so.
      This feature will also not reply to any calls already showing in log again this feature will prevent Dx or Dx expos from double logging and wasting valuable time on repeat callers

      Filter function is now available in FT8
      The clearing of Dx windows and the ability to send and RRR then a 73 has also been addressed
      There have been cosmetic features add at user requests

    • Changelog: 12th December

      The goal is to keep callsign in DX Call window if you called DX and DX operator has answered to other operator.
      So you could wait for his 73/RR73 message and call him again. Now 73/RR73 message in such scenario will be printed in the RX frequency messages window, with no respect to the real frequency this signal is decoded.
      There is now 4-period guard timer that will ban auto prompt to log QSO or automatic QSO logging if you transmitting 73/RRR/RR73 message again to the same callsign that has just been logged.
      Also other modifications are being worked on currently to further enhance user features and prevention of QRM and ease of use.
      Please use the QRM prevention features available. Configuration window: Sequencing "halt Tx", this will make all users experience pleasant
      Tx watchdog: will have Tx after 7 transmissiom (current implementation)

    • Changelog: 10th December

      Reworked replyToCQ() method responsible for getting control from external software, like JTAlert

    • Changelog: 9th December

      T10 symbol is changed to +, FT8 to ~, posting decoded messages via UDP is open there and this step will work with the latest JTAlert 2.10.6.
      Also this step shall work with Logger32 and Swisslog.

    • Changelog 8th December

      FT8 is currently partly implemented in JTDX 8th December.
      There is still development work to be done to fully implement all current JTDX features for FT8.

    • Changelog: 15th November

      More improved accuracy of the QSO start/end time logging.
      Following a post from Steve VK3SIR, JTDX Autoseq can handle many different forms of reply as expected or unexpected during a QSO.

    • Changelog: 14th November

      There is better handling of QSO time_on: callsign checking added at report and roger+report message transmission.
      This patch shall fix an issue where two contacts in the log have the same QSO time_on.
