The Good the Bad and the
Ugly
It's difficult to understand why some folks create and send damaging Virus,
Trojan,worms, etc. I find I am asked to update my Norton AntiVirus program every
few days for all the new Virus now on the web and also arriving in e-mail. If
the Junk or "Spam" mail was just not bad enough. I am happy however
to announce my local web service provider "ISP" is now providing a
VIRUS and Junk mail filter that is stopping this problem.(Several have
unknowingly got and sent the "Badtrans B worm to me). We also have
those that at times like to interfere with SSTV on the popular
frequencies that occasionally the FCC are able to catch and remove and give
fines to etc. .If you don't have a virus protection, pick up a free copy of
Norton at http://www.symantec.com/downloads/
(Note: for Lids and Jammers no fixes or filters are available yet)
No
Free Lunch
Like 70 percent of Americans I spend lot's of time
on the web and find and down load lot's of free programs and services. I have
used several free Web Phone and Video and Voice mail programs that are no
longer available as an example "Rocket Talk" and "Media Poster" etc.,
This loss came as no surprise as it seems the Silicon Valley Dot Com's
were using a business plan of "lose a dollar on every deal and make it up with
volume" and simply just went out of business. My computers can still find some
excellent programs and can even take voice dictation and type at 100 WPM and
also read text to sound, and find and save free MP3 Music to play and
copy and burn CD's, scan and print photographs and web graphics, run
SSTV, read bar codes and keep time, make and send movies and the list goes
on and on.
If You Build it They Will
Come
In America we have a big demand for wide band web access. For most it
is unavailable or too expensive. Current broadband providers including
Satellite, Cable and DSL Telcos only provide a small percentage of users with
this service. It's very unlikely we will ever have fiber optic service in most
of rural America. However just like in the early TV days folks were forced to
setup towers for a shared community TV cable
system. One solution is the use of wireless web connections like
802.11b or (Wi-Fi) I understand this is already popular in Europe. (Even in my
little town on the Oklahoma prairie ,wireless service is commercially available,
at a price, however. Schools are starting to use 802.11b and Kids are even
stringing CAT 5 LAN cables across yards linking homes for fast web connections
and some neighborhoods are putting up wireless web transmitting antenna systems.
Is Windows XP worth It?
I've found XP to be rugged and boots up fast and the 32bit programs run
faster and it has several nice features like the ability to convert text to
sound and provide a magnified display etc. XP can also make little movies to
send in e-mail But how bout the cost? If you live in the USA it is $98.00
for the home edition CD if you are in the far east I'm told you can
pick up a Hacked, Knock-Off, Boot Leg copy for $1.00 or $2.00 (looks like
they found a way around the WinXP Micro Soft register function.)
SSTV INTERFERENCE by A.J Claude
KC5RW
To minimize the QRM on the popular SSTV frequencies I suggest we do not
start a transmission using a picture but instead use a voice message first
to identify and even give the mode to be used. (some times several are
sending a picture at the same time and we have only interference with out a
proper picture.( During weak signal or poor band or noisy conditions the VIS
detection will not select the correct mode!)
Digital Voice/SSTV the Next New Mode?
Have you seen the new January 2002 QST magazine article explaining the use
of digital voice and possible Digital SSTV communication. They indicate that
Digital Video is perfectly legal on the HF phone bands
designated as "J2F" Note: the Baud Rate for digital phone transmission is
unlimited! (For more information see the ARRL web site at http://www.arrl.org/tis/info/digivoice.html
You will need the PDF reader installed to view the site. (PDF read only download
is available free)
Can this be the next big break through for voice and visual
communications?
