JTDX 2.2.0 rc154 (10.12.20)

There is rc154 win64 build based on Hamlib commit


for those users who reported CAT issue with Yaesu radios.



JTDX 2.2.0 rc154 (09.12.20)

Cumulative changelog of rc154:

- patch to increased FT8 decoder lag issue
- avoid storing double type values in settings file to prevent any possible conflict with user regional settings
- translation updates
- JTDX 2.2.0-rc154 is built with modified Hamlib, based on Hamlib commit


  as of December 7th, 2020


win64 build made under Qt 5.15.1
win32 build made under Qt 5.9.5


JTDX.ini file changes:
deleted parameters DTCenter, TxDelay
added parameters DTCenterInt, TxDelayInt



JTDX 2.2.0 rc153 (07.12.20)

- patch: fill in the FT8 candidate list at valid DT range

- patch: pick up some dropped FT8 candidates at one- and two-thread decoding
- changed automatic thread number selection algorithm in FT8 decoder:
number of logical cores/number of decoder threads
1 / 1
2..4 / (number of logical cores)-1
5..8 / (number of logical cores)-2
8 ..15 / (number of logical cores)-3

>15 / 12

- FT8 candidate list thinning option is implemented for usage with slow CPUs to let user get acceptable Lag value, "CL" spinBox is added in mainwindow UI with tooltip
  Default value is 100% (no thinning). Candidate list thinning should be used together with "minimum" wideband FT8 decoder sensitivity setting.
  FT8 candudate list thinning being not applied to the QSO RX frequency. Factor 3.0 being used for thinning under frequency "Filter" option, for instance if CL spinBox set to 30% then thinning factor will be 90% (0.9) under frequency "Filter" option.
- implemented DT weighting and decoding pass weighting to FT8 candidate list thinning option, resulted in improved decoding efficiency.
  User can now select median DT value in DT spinBox of main window UI to get best FT8 decoder performance under candidate list thinning option, DT median default value is 0.0 sec.
  Median DT value of decoded signals depends on accuracy of system clock synchronization, in SDR setups it can also depend on RX audio delay. On overcrowded bands median DT value is usually close to average DT of decoded signals.
- FT8 decoder fast/medium/deep options are obsolete now and deleted, FT8 decoder running now in deep mode.
- multiple changes to FT8 signal synchronization in decoder: improved FT8 decoder efficiency on overcrowded bands
- a bit improved decoding of FT8 signals in 'use subpass' option
- simplified Hint decoder control
- FT8 mode: Hint group of decoders is always used, access to Hint button is blocked
- display estimated lag at decoding FT8 or FT4 wav files, estimation can have acceptable accuracy starting from 2nd even or 2nd odd decoded interval while playing pack of consecutive wav files
- patch: prevent crash with callsign index in chkfalse8.f90
- "Call higher than new calls priority callsigns" option is implemented to AutoSeq 4+, control is in AutoSeq tab of main window UI
- a bit faster displaytext processing
- fixed bug in CQ and ITU zone notifications
- added DX Call notification by the font color change to Other standard messages color
- show CQ and 73 messages marker char with CQ color for LoTW users
- prevent unneeded rig_close/open actions on Configuration settings change accepting
- option added to allow 160m crossband operation with South Korea, control is in Misc tab of main window UI
- track Monitor button state at Configuration settings changes and tuning
- forbid RRR message transmission in FT4 mode for compatibility with WSJT-X FT4 message protocol
- dark style correction in Configuration and widegraph UI
- better handling of large vertical size of the main UI window
- grid square for /MM /P /MM /A /M callsigns shall not be taken from CALL3.TXT file
- prevent saving WSPR files if "Save None" is selected
- fix 4m band default frequency at hound mode checking
- fix removing last audio .wav file on mode change
- added 70cm band FT8 frequency, frequency list reset in Configuration settings is needed to get it displayed in the list
- option for displaying frequency value in waterfall, "Freq" checkbox is added for control
- "Bars" checkbox is moved to controls widget of widegraph
- disable rig power on/off option if other than Hamlib CAT selected
