Version 4.0.1
Upgrade release
– new functionality
– Winkeyer interface
– improved modem performance
– improved logbook performance
– upddated documentation
– Russian translation file
OS X 10.12 build
* Compile changes for OS X Darwin 10.12 Clang build
STATION_CALLSIGN
* Change adif field STATION_CALL to STATION_CALLSIGN
compliant with adif specification
Free BSD mods
* Compliance mods for current version of Clang compiler
Logbook mods
* Update log field LOTWSDATE for each record sent to LOTW when the upload file is created
* clear LOTWSDATE field if lotw rejects submission or fails to respond within 25 seconds
* insure that lotw review dialog closes on program exit
* restore tabular sort order when adding a record
Default Tx Audio
* Change default audio output to both channels
remove sprintf
* change all remaining occurances of sprintf to snprintf
Documentation update
* New documentation for winkeyer interface
n3fjp logger search
* set initial search for n3fjp server to 5 second
intervals
fopen -> fl_fopen
* update to UDF-8 compatible fopen call
48 bar macro
* allow user to select above / below Rx/Tx panels
CW decoder
Improved CW decoder
– removed user adjustable signal level controls
– added automatic tracking filters for Rx signal level
– tracking filters change parameters with detected WPM. Not Kalman, but better than fixed.
DX cluster
* Update dxcluster QSY to correctly align signal to sweet spot when transceiver is in a CW mode.
* add ability to respond to password prompt
Logbook support
* Add checkband test to new log entry before writing record
* Added BAND control to log view, contest tab
– fldigi does not use the BAND field, it is present as a
convenience for exporting or importing from log programs
that do use it.
– the control is on the contest tab since that seems to be
the most common use for BAND (e.g. field day event).
* OS X file naming dialog drops the “.adif” extension.
– add code to insure newlog etc have the correct extension.
WinKeyer
* Added embedded WinKeyer interface
fsq ifkp s/n computation
* Additional change to s/n measurement
fltk version update
* update all fluid generated source and header files
Macro Date Time Formats
* Allow user to specify the date time format using strftime format strings
– becomes <ZT:”%H%M%S”>; <ZT:”%H:%M:%SZ”> etc.
– fmt is the strftime format string
if the ‘:fmt’ is not in the macro tag then the current format is used
lotw addition
* Add jt9 modes for lotw upload
* Allow up to 7 numerals in frequency element
THOR/IFKP Image transfers
* Add auto save Rx images to
– Thor
– IFKP
* Corrected IFKP send image sequencing
– pic%[T] where T is image scale was not being
send before the image fascimille.
* Added Thor and IFKP image transfer using the
macro tag
ifkp s/n update
* Change to s/n measurement
– noise measured over full range of possible signal bins
– noise referenced to 3000 Hz bandwidth
fsq s/n update
* Change to s/n measurement
– noise measured over full range of possible signal bins
– noise referenced to 3000 Hz bandwidth
OSS bug fix
* Add missing parenthesis to reverse audio test
– bug fix submitted by Guiseppe, IZ1QZE
PSKMAIL PTT fault protection
* add REQ(…) to show_tx_timer function call
Logbook File Handling
* Change new log file naming paradigm
– move logbook open/save/merge to a separate sub-menu
* Change logbook merge logic
– discover and cull duplicates in both current and merge records
– write duplicates to adif file for user review
– annotate Rx Panel with user information on merger performance
Russian UTF-8 translation
Tooltips
* Correct and update various tooltips
n3fjp contest update
* Add read next serial to send from n3fjp logger
* Add send TXTENTRYSERIALNOR to n3fjp generic logger
* Add new macro tags
– current serial number
– last serial number
* add support fields for N3FJP NAQP contest logging
Hamlib/RigCAT/XMLRPC Interface
* Hamlib (K5JAE)
– Add user adjustable poll rate
– Add Defaults button
– Modify activation of controls based on hamlib selection
* RigCAT (W1HKJ)
– removed btnRevertRIGCAT & associated functions
– toggle Initialize button state with change in rigcat enable
* XMLRPC (W1HKJ)
– toggle Initialize button state with change in xmlrpc enable
