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

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.

  • 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)
  • 'Time overlap' for problem-free reception of weather charts that are transmitted with delay.
  • 'Merge' -function for combining schedules

  • Optional CW-identification at the end of each transmission.
  • Automatic 'QSO-number' for contest operation
  • Auto-TX after RX
  • Pre-selection for transmitting pictures only partly. (good for contest operation)
  • Rename function in the "open pictures" window
  • 'Safe' delete: manually deleted pictures are now moved to the waste bin.
  • Backup-funktion for the catalog which in most cases prevents the catalog from getting corrupted when the program hangs.
  • 'Rebuild' function for the re-creation of the last received and last repeated catalog pages when the catalog file gets corrupted.

  • Desktop icons can be made invisible when JVComm32 is running.
  • One can now enter full paths / filenames in the filename field of the date editor for scheduled reception. If the path does not exist, it will be created automatically.
  • Some other small bugs fixed.
  • Log files (action log, repeater log) are now stored in a separate 'logfiles' directory.

SSTV:

  • Built-in SSTV repeater with tone activation, beacon function and many other 'goodies'. (repeating P-modes is now working correctly)
  • Up to 999 pictures on the 'last received' catalog page.
  • The percentage of the RX window that must be filled for a picture to be saved can now be selected individually.
  • The number of missing sync pulses that stop reception can now be selected.
  • When pictures are deleted from the catalog, the program now asks whether or not the pictures are to be deleted from the hard disk as well.
  • Pictures in the catalog that are located on CD-Rom or diskette are no longer reoved from the catalog when the CD or diskette is not mounted at JVComm32 start. When trying to open such a picture from the catalog, a message appears that asks for the insertion of the correct CD.
  • Texts entered in the fields Call and Handle of the Text-Tools are now automatically converted into capital letters.
  • Some new shortcuts for date and time. (Text-Tools)
  • 'Set TX mode to last RX mode automatically' button.

  • Fully supports the new PTC-II firmware, with TX handshake (no more TX slant correction).
  • Program now looks optically acceptable, too, when you're running 'large fonts'.
  • New, addional registration scheme. You can now enter a registration code instead of copying a registration key file.
    This might help fix problems that sometimes occurred when sending key files via the internet.

SSTV:

  • Robot 36 (for MIR enthusiastics).
  • Crop/Stretch to fit function. Makes every picture fit into the picture window without margins.
  • The 'Last-received' tabsheet of the catalog may now contain up to 250 pictures.
  • The other catalog tab sheets now accept a virtually unlimited number of pictures.
  • RX-window can be sized freely.

  • 'Quicktext' popup menu by which you can paste pre-defined texts quickly, now.
  • Font, color and text style of the 'Quick texts' can be set individually for every 'quick text'".
  • User paintable header for SSTV transmissions: Create your own header by making a 340x16, or 640x16 (P-modes) .BMP file.
  • When pasting pictures into other pictures, the top margin will not be cut any longer.
  • Bug fixed: When closing a picture that is currently being transmitted, the progam will now refuse to close instead of hang.
  • 'Open pictures from clipboard automatically' button. If down, all pictures that are saved to the clipboard by other programs are automatically opened by JVComm32.
  • Bug fixed: 2300 Hz tone burst button is now labeled correctly

FAX:

  • Fax tranmit in B/W (gray levels).
  • The digital headers of geostationary satellites can now be logged into a file.
  • Bug fixed: If the 'Close' button in the 'open pictures' window is being clicked on while a picture load is in progress, the progam no longer hangs.
  • The RX-window now 'memorizes' its position and sice for each fax mode individually.
  • When autoprint is on, bo black margins are printed when receiving NOAA satellites.
  • Automatic selection of portrait or landscape format when autoprint is on.

 

That's new in version 0.96c ß:

General:

  • To be precise, this isn't actually a new version but rather a collection of bugfixes with respect to the sound mixer problems of the 0.96 / 0.96a version.
    The mixer control that is built in JVComm32 should work well now with most sound cards. If the 'disable JVComm32 mixer control' is activated, JVComm32 no longer interferes with the sound card's mixer (in case the built in mixer control of JVComm32 still won't do with your sound card)

SSTV:

  • The transmit progress bar is now displayed correctly when transmitting one of the 'P' modes. It has become 'faster', too. This should fix some timing problems on slower computers during transmission.
  • Copy RX picture to clipboard automatically button now works as expected (the old 0.96 version always copied the received picture to the clipboard).
  • Additional 'copy RX picture to clipboard' menu item
  • Pop up menu for the RX window with 'Copy to clipboard' and 'Clear window'
  • Color of scope display changed to yellow

FAX:

  • 'Black' and 'White' limits are now correctly displayed before reception starts.


That's new in version 0.96 ß:

General:

  • A 'do you want to quit' query when terminating JVComm32.
  • Audio level display when using a sound card.
  • Audio recording and playback levels can now be set within JVComm32. JVComm32 memorises the level settings for the different FAX modes, and for SSTV and resores them at program start. By this, you can set the optimum recording level for each mode individually.
  • Selectable input for sound card operation (Mic in, Line in,...)
  • JVComm32 no longer tries to initialize an eventually connected picture scanner at program startup.
  • No more expiration date.
  • New 'hide all windows but RX window' button to save space on the desktop.
  • Help file is now up-to-date. (but in poor English, sorry)

SSTV:

  • Buttons for manually starting reception and phasing the received picture.
  • SSTV-toolbox with slant-correction, different tone bursts, and a select box to override the 'identification' setting from the configuration window.
  • Received pictures can now be copied to the clipboard automatically.
  • Modified SSTV pictures (with added text, for example) will now be saved with the modifications when being dragged into the catalog.
  • The setting for the backgrouund color in the text tools no longer gets lost.
  • Pictures are now sent entirely, including the very last pictue lines.
  • Transmit progress bar no longer blinks or disappears during trasnmission when the text tools are selected.
  • Undo-function for modified pictures.
  • 'Copy from Clipboard' now accepts more formats. E.g. pictures put to the clipboard from Paint Shop Pro are now accepted.
  • Extended drag and drop: Now, you can drag & drop picture files from the Explorer, or from some Thumbnail vievers directly into the catalog or have them directly opened by JVComm32. (tested with ACDSee32)

FAX:

  • Selectable demodulator response-curve for AM-FAX reception (lin/log).
  • Received pictures can be printed automatically
  • The automatic saving of the received pictures can now be disabled.
  • FAX-toolbox with slant-correction, auto print-button and adjustable APT-squelch threshold.
  • Crop-function für stored pictures.
  • Histogram equalisation for stored pictures (to maximise picture contrast).
  • Undo-function für midified pictures.
  • 'FAX' menu item no longer is deactivated after a mode change.
  • Drag & Drop: Now you can open picture files by dragging them onto the FAX control panel in the JVComm32 main window directly. Should also work with the popular thumbnail viewer programs (tested with ACDSee32)
  • The colorisation of the pictures of geostationary satellites by mask files can now be disabled.
  • Saved 'out of phase' pictures can now be 'manually phased'.


That's new in JVComm32 0.95 beta

General:

JVComm32 now supports the brand new Hari-Fax 4 interface!

Improved support for the PTC-II:

You can now select the terminal baud rate (SERBaud) to control the PTC-II By this, there's no longer a need to set the PTC to 38400 baud or autobaud.

The PTC-II 'TNC' parameter can now be set to values different from 0 Transmitting SSTV with the PTC-II is now possible on fast computers:

Since there's no handshake between the PC and the PTC, the computer must be fast enough to deliver a continuous data stream via the serial port.

Bug fixed which caused the program to hang when being switched between AM- and FM fax modes

Bug fixed bug in the 'Picture' menu. This bug caused JVComm32 to hang from time to time when one selected an opened picture via the menu.

Some other minor bugs fixed.

Drastically improved multitasking performance when using the sound card.Spanish help file

SSTV:

A TX-offset for the data rate can now be set. This is necessary for some sound cards whose data rate is slightly different between reception and

transmission.

Also necessary when using the PTC-II to transmit pictures.

 

New 'Scan Button' You can scan pictures directly into JVComm32 from a TWAIN compatible source.

The transmit window has been entirely redesigned.

A scrolling bar now shows the actual transmit position.

While transmitting, Text and other pictures can be inserted into the not yet transmitted part of the TX window.

You can insert the automatic insertion of your call sign into the transmitted pictures now. (not in the demo version)

Fragments of other windows overlapping the RX or TX window no longer mess up the stored/transmitted pictures.

The shadow color of shadowed text can now be selected.

FAX:

JVComm32 now memorizes and restores the last zoom factor setting for each FAX mode.

That's new in JVComm32 0.94 beta

Bug fixed in slant correction: When having selected 11 kHz

sampling rate, the slant correction wasn't effective

Data rate was set faulty when using interfaces other than sound cards.

(was a new bug in 0.92ß)

Non initialised variable in offline-mode fixed:

From time to time, the programme went offline witout any reason.

Occasionally, the RX-window disappeared.

'List Index out of bounds' bug eliminated.

Registered programme versions are no longer bound to one single computer.

Registration is now only bound on name, first name, and call sign.

Older, machine-dependent keys are automatically converted to

machine-independent keys.

Double-clicking on the TX-button no longer hangs the programme.

(Dieter Pock, DG3EG)

The small pictures from the catalog tab sheets can now be directly

dragged and dropped onto opended pictures.

To do this, click on the thumbnail image you want to drag and keep

the left mouse button pressed for more than one second. Then you can

drag and drop the picture onto any other open picture. (Kazuhiko Ishizu)

Entire catalog tab sheets can now be cleared (i.e. all pictures are

removed from the sheet) via the context menu (Dieter Kraft)

Minimised opened pictures can now be closed without hanging up the

programme. (Dieter Pock)

 

 

That's new in JVComm32 0.93 beta:

The sound card sampling rate can now be switched between 8 kHz and 11 kHz.

Whenever possible, one should use 8 kHz, but, with some sound cards,

the 8 kHz frequency is so far off the correct value that receiving

SSTV becomes nearly impossible. In this case, one should change to 11 kHz.

An new "100%" zoom factor enables using the full screen width when

receiving FAX pictures.

The multitasking perforance when using sound cards has been improved.

It's not yet optimal, but already much better than before.

The 'open picture' window in SSTV or FAX now stays open when

loading a picture to make possible the quick loading of multiple

pictures.

There's a 'Copy to Clipboard' button in the SSTV catalog window now.

That's new in JVComm32 0.92a beta:

When the real sampling rate of your sound card was too far off the 8 kHz,

JVComm32 refused to display a picture in SSTV and reported

'unknown mode', instead.

Due to this one had only an odd chance to do a slant correction in SSTV.

The only cure for this was to do the correction in FAX mode.

In this version, I increased the tolerance threshold for the mode

recognition so that even extremely slanted pictures will

still be displayed.

I hope this will help those who had problems with the 0.92 beta.

Please make sure your sound card supports an 8 kHz sampling rate.

The standard 16 bit sound blaster does.

Another small bug removed that prevented JVComm32 from

displaying absolutely slant-free pictures in SSTV.

Expiration date prolonged to Dec 31th, 1998

The expiration date is not a feature of the demo versions but of

the beta releases, instead!

That's new in JVComm32 0.92 beta:

Sound card sampling Rate has been reduced to 8 Khz. At the same time,

the programme's internal samling rate was increased to 6 kHz. This

gives a better picture quality and is less time-consuming than before.

(Eventually resulting in a better multi tasking performance)

Digital header recognition of geostationary satellites improved.

If a header is not recognised correctly, however, the programme

no longer hangs with an error.

Comfortable slant correction.

VIS codes for P3 , P5 and P7 have been corrected.

QRM modus for SSTV: when on, a picture isn't interrupted until the entire RX window is filled

JVComm32 now generates a JVREG32.bin file for registration insteadof a

.txt file.

.Txt files seem to be modified when being sent via the internet from

time to time.

Some bugs removed; the programme should run more stable now.
