JVComm32 program history:

What's new in versions 1.23 .. 1.26 pre (2002-11-02)

General:

• Automovie function for the easy creation of cloud movies
• Some minor improvements and bugfixes.
• Improved serial port routines for the PTC-II, etc.
• "Reset" button to set back the JVComm32 configuration into the initial "factory" state.
• Quick Start & Troubleshooting Guide now included in the installation files.
• Adjustable thread priorities for the different program threads. This might help avoiding the "stair step" problem that occurs on some computers.
• Improved routines for remotely setting the frequency of receivers and transceivers via the serial port. JVComm32 can now directly set the frequency of some Yaesu, Icom, and Kenwood devices. IN additon, a simple ASCII output routine for controlling the frequency was added.

RTTY:

• The smart message viewer can now be opened from the main menu. So you can receive weather charts while you read the weather forecasts, etc.
• New RTTY-Mode editor. Define you own RTTY modes. 850 Hz shift and 75 baud are now possible, too.
• By the "Decode / add messages from text file" button, you can load external Synop- or Navtex-Texts into the message viewer.

What's new in version 1.22 pre: (2002-03-23)

General:

• "External" mixer control for "nasty" sound cards. If the JVComm32 internal mixer control is disabled, two additional buttons appear in the JVComm32 main window by which the Windows standard mixer recording and playback volume windows can be opened. An additional "auto" option in the sound card select box makes JVComm32 use the default Windows audio device.
  
• The data rate entry for sound cards is now based on the 11.025 kHz standard sampling rate of the sound card. If you have any other programs running with the sound card, and you already know the precise data rate of your card, You can enter this value, and thus save some time that otherwise was needed for doing the slant correction.

RTTY:

• "Sort-buttons" in the Message Viewer

FAX:

• Manual movie creation now possible
• fixed bug in movie player

SSTV:

• New "MP" SSTV modes (invented by Makato Mori for MMSSTV)

What's new in versions 1.10 pre .. 1.21 pre: (2002-02-23)

General:

• RTTY-, SYNOP- and NAVTEX-reception for the reception of meteorological/navigational warnings
  
• Better timing (probably less or no more "stairsteps")
  
• some bugfixes and changes to the audio mixer module.
• some minor adjustments to make the program run better on Windows XP

RTTY:

• reception of RTTY- and NAVTEX messages with the sound card, or the PTC-II.
  
• "NAVTEX/RTTY database" with a viewer to comfortably browse through the received NAVTEX/RTTY/SYNOP messages.
  
• In the viewer, messages can be filtered by types and/or stations.
  
• Fine tune option for the demodulator center frequency. By this, it is very easy, now, to receive RTTY and NAVTEX with receivers that only very coarse tuning steps.
  
• For receivers with a poor frequency stability, an AFC can be activated.

FAX:

• "manual phasing" for HFFAX now works during the whole reception period.
  
• PLL-demodulator for NOAA reception (no more "banana shape" pictures)
  
• Special histogram equalisation for NOAA pictures.
  
• Special palette "stretch" function for normal and NOAA pictures

• Black threshold for geostationary and LEO satellites is now adjustable.
  
• When recieving geostationary satellite pictures with picture masks, the white and black masked areas can now be inverted to save ink or toner when printing the pictures.
  
• The computer's clock can now be synchronised by the transmissions of geostationary satellites.
  
• File name format for the saving of FAX pictures can now be freely chosen.
  
• Optionally, an external program can be called whenever a picture was received. By this, one can easily upload a received picture to a home page via FTP, for example.
  
• In the viewer, on can now rotate pictures also counterclockwise.

SSTV:

• PD modes 50,90,120,180,240.

• "Stack pictures" works again. Additional "Stack pictures" button.
  
• "Callsign in Picture" text can now be configured.
  
• "True" CW-ID when transmitting over the sound card.
  
• No more problems with write-protected pictures in the catalog window.
  
• Optionally, an external program can be called whenever a picture was received. By this, one can easily upload a received picture to a home page via FTP, for example.
  
• "Rebuild page" command works for all catalog pages. Thus, garbled catalog pages can be rebuilt, e.g. after the color resolution, or the graphics card is changed.

What's new in version 1.00: (1999-12-24)

General:

• Significantly improved filters for sound card FAX & SSTV reception.

• Now, there can be assigned different sound card inputs to the different program modes. (SSTV, FM-FAX und AM-FAX)
• New command line parameters for controlling JVComm32 in batch procedures. The sound mixer control can also be disabled by a command line parameter, thus enabling operation under Windows NT 4.0 with some odd sound card drivers.
• Additional .ini files for PTC-II operation: PTCINI, PTCdeINI, PTCFAXINI, PTCFAXdeINI, PTCSSTVINI, PTCSSTVdeINI. In these files, one can place additional commands for the PTC-II which are executed at the startup or termination of JVComm32, or at the startup and termination of a specific JVComm32 mode.

FAX:

• For weak geostationary satellites receiving conditions, the mask file/palette assignment can now be determind by a "schedule file" instead of the digital header evaluation. (these .sche files have the same format as for the old JVFAX program)
