Uh,, Bob, that isn't traffic, It's *data*. I guess if you were really
familiar with radio
you;d know that, wouldn't you?


Uhhh, DICK, you should know that weather data can be passed via many
modes, and that satellite imagery is referred to as wefax or wxsat.

Typically, what is called "DATA" is RTTY.


No, Brian, digital information that is not analog voice is generally known as data
tansmission.


Sorry, senior.

But all that is old technology. Today, we get our weather via
wideband, though you're free to play with UKMO and NAM transmissions.


I guess you missed the entire point that WEFAX isn't in any circumstance handled by Morse
code. That is reserved for text communications or coded letter groups.


Poor DICK. I guess you missed the entire point that useful satellite
information could be sent via Morse/CW, if you were willing to develop
the protocol and the overlay grids, similar to the old gridded radar
bulletins.

For what its worth (FWIW), real satellite data isn't pictures, isn't
FAX. It is rows and columns of pixels, each with a value ranging from
zero to 255, seven layers deep. They are formatted into data groups,
and 'puter programs display and/or animate the data with various
enhancement curves (algorithms) which make the DATA more useful.

which I learned as a requirement of my licensure as a
ham radio operator. There is no reason for you to be exempted from the
same.

Well, at least you finally admit that it's "I had to do it, you
should too."

The difference is, I know why. You obviously don't.


Couldn't be much of a difference since you obviously don't know why.
And I know why you don't. You're simply ignorant about weather comms.
Stick to things you know, such as CW and more CW. When you're done
talking about CW, you could switch to Morse so you don't sound like a
broken record.


More gibberish and attempted bafflegab. That's all you know so you stick to it.


Gibberish and what? I know meteorology and weather comms. I'll stick
to that and you can deliver the "bafflegab."

And FWIW, radar image intensity bulletins used to be transmitted via
tty, and the receiver had to plot it on a predetermined overlay for
that particular radar station. So the concept is there for satellite
data transmission, but was never implemented. So go and create a
satellite overlay grid, then encode satellite IR temps (if you can),
and get cracking on Robert's idea.

See, you CAN use CW to send useful information rather than just ARRL
numbergrams.

73, Brian


Piffle. THAT is an obsolete use of Morse code.

Using it to pass message traffic when radio conditons are such that it works well but
other available modes won't is another matter, as you know.


I'll take wideband any day. You take "bafflegab."
