Yes the time like morse conveys the information but all
RTTY transmissions that I have seen are FS Keyed IE MARK/SPACE
You could do the reverse and read the Space
elements.
The transmitter idles on Space then keys the Info on the
Mark frequency

...... That's not fsk as the tones
would need to be sent in parallel ,
the position conveys the info , not the shift
slow scan tv a picture of a punch tape
..... suppose with a little time and soundforge could
make up a tape and send it via ssb

If you want to SEE the code in a waterfall, instead of
DECODE it with a SW (or HW),
what is the advantage of the Murray/baudot
code compared to CW?
I am confused..

Mauro this is one way to generate 5 unit Murray code or a more basic method
is the Mechanical Perferator keyboard.
This is an interesting subject and
requires Operator skill like being able to TYPE properly and also be
proficient at the Murray code.
Let me know when you are ready to receive
a message on your screen in FSK Murray code (slow
RTTY)

- It is interesting to see who is on the band but NOT a machine
uttering gibberish most of the time.
- One thing that has been neglected is MURRAY CODE being transmitted
like QRSS. It can be sent at various speeds and can be read directly
off the screen like DFCW. The Murray code can be learned like MORSE
and when used by the GPO years ago the speed to qualify was 15 wpm
reading from an undulator tape.
- Since it is a ONE level mode and with todays technology can be
read directly on a screen it would be a good alternative to DFCW
- 5 unit Murray Code - start learning - real Radio Operator

- 54 machines listening to each other and not a Real Operator
about. This is a good example of Appliance Operator activities.
This is not Real Amateur radio, there is no personal touch. Leave
your machine unattended and hope for the best when you return from
a night out or get up in the morning.
- Is the the future for
MF??
- No, the future is for CW! :-) If CW dies out then the whole
amateur radio dies out. It would not take to long then because CW
never becomes boring. It is fascinating to experience to listen and
to instantly "decode" the dashes and dots. It's like listening to
music.
- However in digimodes, there always has to be a new mode, each
few months. You know that, i know that, we know that. So don't
worry!
- Anyway, there is no reason not to transmit on a ready to use
antenna while beeing outside the shack. This helps to move some
interest from HF to MF and to generate newcomers and so on. Also it
is interesting to see what is possible and to see who is on the band
(or who's PC is on the band if you prefer that).

- Thanks to all the many MF stations who reported to my WSPR
beacon. There were 54 stations since yesterdays evening,
attached below.
- Just came back from the club meeting where i hold my
presentation of the VLF experiments done in 2010/2011. The OMs
were very interested and amazed. There was silence during that
time i told to them :-) Again big thanks to this group, who is a
big part of the Dreamers Band stuff :-)
- I didn't find the time to stop the TX here in the shack so i
am on air in WSPR since yesterdays evening :-) Guess i'll stop
it soon.
