SeaTTY versions history

V2.55

A soundcard number can be above ten now.

V2.45

The Setup / Interface / Soundcard number / ... / Mono-Left-Right option was made.
It allows to connect two signal source to one soundcard.

The Setup / Interface / Nominal sampling rate option was made.
The sampling rate can be 11025 (default), 22050, 44100 and 48000 samples per second. This option can be useful to avoid soundcard driver bugs (some soundcard drivers work bad at low sampling rates) or to connecting to digital sound source via virtual soundcard without re-discretization.

The Setup / Text / Put time stamps in saved text files was made.
UTC or local date and time of message starting are added in a bottom of saved message if this option is enabled.

V2.40

The documentation was updated.

A minor bug in the slant correction procedure was fixed.

V1.80

GMDSS DSC (Digital selective-calling system) HF and VHF messages decoding was made.

V1.76

Station ID's of RTTY and NAVTEX messages are included in message filenames and are shown in the message tree now.

V1.75

The “Setup” menu was rewritten.

Station ID filter was made. This filter allow to select messages which should be automatically saved in NAVTEX and RTTY modes. Station ID is four letters after “ZCZC ” sequence.

V1.74

The “Shift” menu can be used to select normal deviation (800 Hz) or narrow deviation (300 Hz) in the HF-FAX mode now. Narrow deviation is used at Long wave band.

V1.73

The “Setup > Clear Rx Window Once a Day” option was made.

V1.72

Invisible buffer is not used now. Receiving window contains all received symbols until it is manually cleared.

Some internal changes were made.

V1.71

Minor bugs in text displaying were fixed.

V1.70

Minor improvements of raw log files handling were made.

V1.65

NOAA Weather Radio SAME messages decoding was made. Voice messages are automatically saved to wave-files (5 min maximum), SAME headers of a messages are saved to text files.

V1.60

User can select a soundcard by Setup > Soundcard Number menu now.

The Setup > Put Time Stamps in Raw Logs option was made. When this option is selected, SeaTTY writes local or UTC time at beginning of each string of a raw log file.

V1.50

The documentation was updated.

Some minor bugs were fixed.

V1.40

Soundcard handling was rewritten to avoid synchronization losses during FAX receiving.

A number of unprocessed buffers (“UpB”) is shown in the status line in place of number of free buffers (“FrB”) now.

V1.39

A bug was fixed. The program start was failed if setup was saved with “OnTop” button pressed.

The “Start/Stop” button was made to start or stop message receiving manually in RTTY or NAVTEX mode.

V1.37

The “File > Open Wave Capture File” command opens wave-file to save all sound received from soundcard. File is closed by the File > Close Wave Capture File command. The hotkey for these commands is Alt-V”. Take to attention that a minute of sound recording need above 1 MByte disk space.

A frequency ruler was made.

The “Setup > Use UTC time” option was made.

V1.35

Different icons in the message tree indicate different file types (texts and images) now.

V1.32

FAX images are saved in PNG format now.

Second parameter is global deviation in hertzs, i.e. maximal deviation from last user-selected frequency.
User-selected frequencies are shown at spectrogram by short red lines .

V1.22

A problem with FAX synchronization losing while image scrolling was fixed.

If start tone is found during image receiving, SeaTTY saves image and starts new image receiving now.
