I would not care about picture distorsion, but at any but the default
monitor resolution the text becomes blurry (not sharp). The cause is
that any resolution has to be up or downscaled to

I ran a few tests to see just how long it really takes for sending a
document via a digital data program such as WinDRM. If you had a good
path and probably at least a 10 db S/N ratio, the transmission time for
my test document of 29 K was only about two minutes. The test file is a

Kevin,
I am using two soundcards and WindowsXP home addition. If I remember
right the bios for my PC had to be change from a auto detect to always
used. When I get home tonight I re-check my setup for you. What
software are you using?

If you haven't done so yet, checking your BIOS would be a good next
step. Often, the AC97 audio is set to "auto" which will disable the
onboard audio chipset if a PCI audio device is detected. Changing the
to "enable" or "on" may do the trick for you.

Linux has suported multiple soundcards in all it's distros for years.
The most usual way is by adressing them
as /dev/dsp /dev/dsp1 /dev/dsp2 etc but you can also adress the
induvidual parts of the soundcards directly in the latests distros
as /dev/snd/C0D0d where the number after C is the card,
I think you are correct. Text emissions have some sort of code which
indicates the character to be transmitted. Such codes are Morse,
Baudot, ASCII, and Varicode to name a few. Digital facsimile is
pixilated and the pixel's intensity is represented numerically as in
bitmap images. Pixels ar
The FCC rules provide the following definitions for fax:
Image. Facsimile and television emissions having designators with
A, C, D, F, G, H, J or R as the first symbol; 1, 2 or 3 as the second
symbol; C or F as the third symbol; and emissions having B as the
first symbol; 7, 8 o

Jon,
I have no idea about DSTAR, but did do some path simulator testing with WinDRM
and the latest variants as well as the AOR fast modem. Nothing serious, just
some informal testing from PC-to-PC.
The modes were tested for sensitivity and the ability to fight ionospheric
distortion. Some QRM
Has any testing been done on the DV modes above? WinDVM sure looks
attractive as no additiona hardware is required. Thanks for any/all replies.

For me it's because digital=digital and FAX=analog, hi.

That's not universally true, Flavio. Its defintely not true of any of

fldigi can be downloaded from http://www.w1hkj.com/
W1HKJ also has a Yahoo group that supports his software:

Kevin,
I think only Windows XP Pro, Home and Media, some of the Linux distros
also support two sound cards. I may be incorrect though. After
install of the Creative board, try to reinstall the software for the
on board audio device if you have the disk. Sometimes that works.

Saludos Dave,
All LCD or TFT monitors produce severe picture distortion at any but the
default monitor resolution. Make sure that the one you get is not distorted at
the resolution you plan to use. Ever saw an oval shaped circle? Just try and
change the resolution in your monitor to any resoluti
