New SSTV Modes (How many is
enough)
Quite some time back I counted over 27 of the various SSTV modes. It seems
like each time some one creates a new SSTV program or even hardware it includes
new SSTV modes. If some one can convince me of any improvements or advantage of
adding new modes this seems to only make a Babylon type band condition and we
are forced to continuously be up grading to get the big picture. I would
like to receive any comments on this. Ray W5NOO
News Letters in E-Mail (general
information by Ray W5NOO)
We have had some inquires on what is the best way to make news
letters for e-mailing . (some wish to start a local Radio Club news letter)
I have little experience at the web publishing but have experimented with
several ways to send a group type News Letter. I am simply using the Windows
I-E Outlook Express Version 6 e-mail program to compose this letter
and save it as an HTML type file in my Drafts folder and use cut and paste and
font change functions to edit and attach small animation's etc. The
advantage of this is that the file can have colored text fonts and
attachments and has a typical size of only 25 Kb (even a dozen or more
larger letters fit easily on a 1.4 Meg floppy) The Out look Group
mailing function also has all the necessary e-mailing addresses information. I
could make and send a more graphic and complex e-mail page with even video
attachments or even attach or add some MIDI music in background etc.,
but I believe more can receive and view and print or store and prefer this
simple HTML e-mail type information. One additional advantage is the viewer
when on line can also click on the underlined hypertext URL information
links. (Note: The use of the Windows operating system and I-E
6 with the latest Microsoft Critical Upgrades installed is also
less susceptible to Virus attacks)
Saturday IVCA SSTV Net
The Saturday .SSTV net on 14.230 MHz at 15:00 UTC has been in
operation for more than 30 years and I believe is still a very useful way for
Amateurs to locate each other and communicate, especially for the new operators.
As computers have now made SSTV popular and easy and inexpensive to get started
with . The net is one way to help eliminate QRM on the week- end, crowded band
conditions. As the net control receives and replays pictures usually in Scotty 2
mode, your picture will also usually be received over a different area. As
we can successfully only receive one station at a time this is a practical
approach and if stations are impatient they can simply move to a different
frequency. The IVCA net control operators are only
scheduled for net control once every 6 weeks. If you would like to be
a IVCA net control, contact me, Ray W5NOO at ray@junct.com (It's fun......... every one
sends you pictures and you feel like a big time TV program director)..
Voice SSTV Program Control? (look
no hands)
Has anyone considered computer Voice Control for SSTV Windows programs? I
usually use an optical 5 button mouse or keyboard to control most of my SSTV
programs. I do however use the older IBM speech recognition program
"Strictly Speaking Gold" to dictate and read back e-mail and word processor
text etc. . I am also able to run and control several Windows programs using
primarily voice control commands with programs like the Paint Shop Pro and
the Windows Calculator etc. The current sound card SSTV programs however use my
single computer sound card and perhaps a second sound card could provide voice
SSTV system control. Faster computers and large memory and storage with improved
speech recognition are just likely to make us lazy or handicapped
operators that don't type or spell; look and sound good in the future!. (Note:
As I remember we have also used computer multitasking to simultaneously
watch SSTV and commercial TV in a small window using a tuner/capture card and
also play music all at the same time! To avoid chat rooms and waste time
or just for amusement we can also converse directly with the computer when
we dictate or type into several of the free web Artificial
Intelligence (AI) programs.).that have an amusing response to my various
questions and comments! (I just need to get a life)
New Web/Cell Phone
PDA's Hardware Accessories etc. (every one can now go
wireless)
Amateurs were some of the first sending pictures by radio over
the air and over phone lines more than 35 years ago but the web is now
permitting anyone to use an increasing number of amazing new devices
hitting the market. We have several companies that are selling full
featured cell phone hybrids that also provide wireless
video communication with Video capture and color display that
are portable, and also several companies are planning to sell
multifunction devices for wireless web access like the new Handspring
"Treo 180 Communicator". We even now have a small viewing single eye glass
display device that plugs in to a cell phone. The popular Personal Digital
Assistant "PDA" devices like the Palm Pilot and the Handspring Visor
now can have several plug-in, add-on modules to store and play MP3
music or possibly add a Kodak Palmpix camera to capture color pictures and can
also display using a SVGA with a resolutions as high as 800X600
and even a Palm wireless 802 11b module is available . You can also turn
your Palm PDA into a wireless IFR remote control device that will control the TV
or any thing in the house . (For more details do a Google search
for "PDA" or "Cell Phone/PDA") to compare features,functions
and price.(some of this new hardware has some compatibility problems but will be
soon ready for prime time and I believe become popular with the public)
Smart Video Cameras and ComputersI
Perhaps you have learned of a video camera and computer equipped with
a facial recognition program and a mug shot data base that can
identify a single individual or fugitive seated from the hundreds in a sports
stadium. We also now have infrared sensitive cam's and programs that can detect
heat change in a persons face when they are telling a lie with an accuracy equal
to a standard polygraph system. Some previous Sony model camcorders were also
able to see through clothing due to their infrared sensiitivy. New programs
developed can now use video cameras and computers programs to determine the
sex or age of individuals as well. (And I had always thought computer text
Optical Character Recognition OCR was amazing)

Computer Tips (to help keep your confuser/computer
running)
A frequent "Scan Disk" is helpful and generally
necessary with a windows operating system but to eliminate problems when trying
to run the "Defragment" function that's necessary only every few months,
try pressing the F8 key during a boot up and then select the "Safe Mode" to run
Defrag in. This permits using only the minimal number of programs and
functions installed. (Defrag will then usually complete or finish and not keep
restarting when interrupted) Note: After a Defragment it will usually
only result with small increases in computer speed! If you have
problems with a disconnect when trying to do a large program down load use one
of several programs like "Down Load accelerator" that in
addition to a possible, faster down load, it also permits a resume if the down
load is interrupted. It's available free at http://www.speedbit.com
