WEFAX, FAX, SSTV, RTTY with Sound Blaster = OK
Brian E. Cauchi
Hello...
If you have a RADIO and a SOUND BLASTER (or compatible card) you already
have all the hardware necessary to receive WEFAX, FAX, SSTV and RTTY.
You can also transmit monochrome FAX and SSTV, with the current version.
*** Put the power of your 80386, 80486 or Pentium processor to real use ***
The external "decoder" units that are used by conventional users are
modelled inside the software. This makes it easy to get started,
inexpensive and rids you of the inevitable tangle of wires and boxes of
decoders.
Absolutely no external hardware, other than a simple audio lead, is
required by FTV. The current version decodes:
WEFAX (from weather satellites, e.g. 137-138 MHz)
HF-FAX (from terrestrial stations)
SSTV (from radio amateurs, e.g. 14.230 MHz)
Baudot (press, naval, weather etc)
Here is a run down of the more interesting features:
(1) It keeps the demodulated signal in memory, so that the signal can be
analysed again at a different keying rate or polarity! Garbage can be
resampled on the fly, which means that minutes of received signals decoded
at the wrong baud rate or keying polarity are recovered, on the fly, while
still receiving.
(2) The incoming signal is analysed automatically - standard modes, line
rates, baud rates and keying polarity are automatically determined
following analysis.
(3) Tuning oscilloscope available at all times, without loss of copy.
(4) Program works in real time.

Brian,
Lat I tried your software, it crashed under Windows 95. Did you fix it?

Did you try rebooting to MS-DOS mode? Programs that demand heavy duty
CPU time run better (At least run) only in MS-DOS mode (Not DOS IN A
BOX). SBFFT is like this.

Yeah, at least you can get the main screen up if you reboot to DOS mode,
but when you give it the run command, it crashes and burns. It appears
to put the SVGA card in a very strange mode. The monitor goes into sweep
protect. And the only way out is a hardware reset. That's with it configured
for the default 640x480 mode, which should work on any hardware. I haven't
tried it yet in 1024x768. PC is a 100 MHz 486DX4 with 16 Mb RAM running
Windows 95 and using an ATI Mach64 video card and a Soundblaster 16 sound
card. I configured the EMS memory, and at sign on the program Oks that and
finds and checks the sound card Ok too. But give the Run command and the
screen goes dead and the machine locks solid. Not pretty.

Interesting, I tried it last night, and it worked right off the bat.
486DX4-100
Trio S3 svga board
Soundblaster 16 w/WaveBlaster daughtercard
32 Megs RAM
Running QEMM.
I still haven't managed to decode anything yet, but I will persist!
Sorry, but that was the only clue I could offer.

Works for me 486 - 33mhz, 8meg, soundblaster, etc
(Gotta use EMM386 or as Don has Qemm.)
Decoding takes some tweaking but I got it working in the ham
bands on rtty and weather FAX.
Every decoder I have (hardware) really takes tweaking and
experience, I am still evaluating this
software (shareware), but it looks promising.

I also run ATI Mach64 card. (also QEMM)
My vidio card required the VESA driver.
This card has some strange behaviour with
programs that make VESA calls without the
driver.
Look for 64VBE200.ZIP from ATI. Contained
in this .ZIP is the driver M64BE.COM which
is a DOS TSR.
BTW the program runs in an OS/2 DOS full screen
session (with the tsr installed.)

The "other" problem is that Win95 still seems to "own" the
soundcard when you are in a "DOS" box. The program does not like
that. You will get an "interrupt" error or similar.
Make sure himem.sys is loaded in your config.sys and "emm386.exe
auto" is in your dosstart.bat. Exit windows with the "restart
computer in dos mode" menu. You will then drop right into DOS.
I have had good success with it. It works! I got a perfect copy
tonight using a DX-440.
Pentium 120
S3 Vision 330 PCI 2MB
Soundblaster 16 value PNP
64 Megs RAM
Running Win95's stock EMM386.exe and himem.sys
640x680 and 600x800 worked fine, 1024x768 seemed to revert back
to VGA.
Unless you have a "magic" soundcard, you will probably have to
tweak the <esc>/Settings/Demodulator/Clock-cal setting.
Type <ESC> S D C
At first, I got a screen-full of scrambled lines. Totally out of
sync. Slowly decrementing the value, I got it to "straighten
out". It straightens out all the stored data, too. So the whole
image should "snap" into place.
My final clock-cal setting was 0.98698. You may need to step in
increments as little as 0.0001 to "zero" it in.
Good Luck!

it is not dead, it only moved to sunnier places. Simply come home early :)
Don Lafontaine
Now there's a great plan!!
Gary Coffman
Well, I might be able to help you with that. Make sure you have your
EMS memory manager installed in config.sys, and make sure it isn't set
for NO EMS (that's the default way it'll be with Windows). Just delete
the NO EMS from the line and reboot.

Hi jvfax works about the same you can use it on gose noaa i think i got a new
pro-62 scanner with am & fm modes so i might can rx the noaa in the 136 and 137
freq range.
for the converter you can use hamcomm interface that i made and it works.

Hello,
If i understand you, you use a scanner to receive NOAA pictures ?
Could you please send me the frequenties for NOAA and is this wide or
narrow FM ?
The antenna is this also importend ?
Thanks for all your help,
73

sat picture in the 136 mhz is greater than most scanners can handle
without modifications. You would most likely only get part of the
picture (if any at all, assuming the sync pulse wasn't chopped as well).I
would be interested in knowing how you modified the Pro62 to handle this.

Mike,
This is a matter of a simple IF filter replacement for most
scanners. Although wideband IF filters are not available at your local
Radio Shack, they are available from several mail order places. A
detailed description on how to do this appears in the Weather Satellite
Handbook by Taggart.

Today is usesd my scanner Bearcat UBC 9000 XLT and the program WXSAT
(soundblaster) to receive NOAA pictures.
It works GREAT !!! I get the compleet pictures, a friend of me have a
real NOAA receiver and we putt the two pictures together and they are
the same. So my scanner works great to receive weather sattelites on
+137 Mhz.
No modifications on my scanner, and i use a normal dualband antenne for
144 Mhz and 440 Mhz.
