JVComm32 program history:
What's new in versions 1.23 .. 1.26 pre (2002-11-02)
- Automovie function for
the easy creation of cloud movies
- Some minor improvements
- 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.
- 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,
- 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)
- "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.
- "Sort-buttons" in the
- Manual movie creation
- fixed bug in movie player
- New "MP" SSTV modes (invented
by Makato Mori for MMSSTV)
What's new in versions 1.10 pre .. 1.21 pre: (2002-02-23)

new in version 0.96c ß:
- 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 /
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
- 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

new in JVComm32 0.95 beta
JVComm32 now supports the brand new Hari-Fax
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
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
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
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
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.
JVComm32 now memorizes and restores the last zoom factor setting for
each FAX mode.
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
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)
new in JVComm32 0.93 beta:
The sound card sampling rate can now be switched between 8 kHz and
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
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
There's a 'Copy to Clipboard' button in the SSTV catalog window now.
new in JVComm32 0.92a beta:
When the real sampling rate of your sound card was too far off the
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
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!
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
.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.
