fldigi alpha test version posted



and at Source Forge

Many bug fixes and updates. 

The question of why fldigi cannot use DTR/RTS signal line keying for CW has been asked repeatedly.  The answer was that the developers were not able to produce accurate timing.  That problem may finally be solved.

Please note that CW keying is now available using a serial port DTR or RTS signal line. (+12 = keydown).    I have tested the performance on a Yaesu FT-991A using it's secondary USB serial port.  CW signaling at 5 to 40 WPM is clean and the timing is accurate.  The DTR/RTS port can be an independent port, or shared with the RigCat interface.

I would like feedback on this new feature.  Include specifics regarding the transceiver and h/w interface being used.

RSID code assignments
  * Assigned secondary Rsid Codes:
    - DominoEX Micro: 691
    - ThorEX : 693

ARRL CW bulletins
  * changes to CW modem and macro language to support
    bulleting transmissions by W1AW
  * add new transmit interval macro
      <!SKED:HHMMSS:YYYYMMDD> to provide segmented scheduling
    of transmission at exact date/time.
  * change right channel QSK/PTT signal to square wav
    - user configurable base frequency
  * correct Farnsworth timing
  * add timing compensation for more accurate WPM timing
  * modified to work with 1.2.0 nanoIO sketch

lotw mangled report files
  * tqsl trace file occassionally mangled when read by
    fldigi function check_lotw_log.  delay reading file
    until no change in trace file size occurs with a 100 msec
  * improved lotw message box contents based on lotw trace
    file contents
  * increase time-out delays waiting for tqsl trace file

tree metaphor
  * change configuration dialog to use tree vice tab metaphor
  * update user documentation

OS X Bus 10 error
  * Bug fix on OS X.

Log ADIF export
  * Add fields to "all" export

  * increase timeout to 5 seconds

Display Logbook Datum
  * re-enable control of displaying logbook datum when starting program

Rx monitor
  * add monitor audio stream to allow user to listen to
    unprocessed Rx audio stream
  * add Rx audio stream filter
  * create separate Rx Audio dialog
    - open on View menu pull down

Combo Box behavior
  * add scrollwheel action to combo/list box behavior
  * add widget Fl_Group::do_callback() to event handler
  * correct FreqControl handler for scrollwheel

cw prosigns
  * allow user to select cw prosign display
    - long view, <SK> <BT> ...
    - short view, as prosign short cut key
      defined on the CW prosign config' tab

RTTY bell
  * enable BELL, visual and audible for TTY decoder
  * pass BELL, \a, and CR, \r to xml rx data stream
  * add RTTY bell waveform file
  * add user configuration controls to disable BELL annunciation
  * fixed Windows alert failure
  * added ctrl-shift-g to special character group to insert
    the <BEL>, 0x07 character into the transmit text
    - hold control and shift down and press g multiple times
      for a string of <BEL> insertions
  * clean up trailing edge of phone ring
  * implement separate thread for handling mp3 and wav file playback.
    - removes dr_mp processing from main thread
    - prevents main thread locking during mp3/wav file processing

MinGW mods
  * changes imposed by changes to gcc and mxe components
  * modifications to accommodate changes in mingw libraries and headers

CW International Chars

  * Add mp3 decoder for mp3 files
    - uses public domain decoder drmp3
    - Audio playback, and
    - Alerts

  * Allow CWID execution at specified position in macro text
  * Modify macro tag <TIMER:nnn> to always start when state changes from Tx to Rx.
  * Add <# comments> tag.  Works same as <COMMENT:comments> tag
  * Correct coding for proper operation of <SKED:..., <TIMER:...
    and <REPEAT...> tags.
  * Implement <UNTIL:hhmm[ss]:[YYYYMMDD]> macro tag
    - halts macro at specified date/time when either <REPEAT>,
      or <TIMER:nn> are specified in the macro text.

Xmt Audio file
  * Add ability to transmit an audio file using new macro tag: <AUDIO:path-filename>
    - macro editor opens an OS select file dialog
      when the tag is selected from the pick list
    - suggested use:
      <RX><@MODEM:BPSK31>  or modem type of choice
  * Audio file must be wav format, either mono or stereo any sample rate
  * Returning to Rx stops current and any pending audio
    playback.  Post Tx macro tags are then executed.
    T/R button or Escape key will abort the playback.
  * Please use responsibly - know and understand your license limitations
    for transmitting audio files, especially music and/or copyrighted material.

  * Correct test for no output device
    - do not use pa error handler
  * Add ability to select the pa device for alerts output
    - was using default device
    - detect device default sample rate
    - convert all sound files to def sr using fastest sinc converter
  * Change output to use pa callbacks
