So Mal the acceptability of a mode is based on the intelligent human
being able to read it direct from the screen.
WSPR (not the QSO verion) is a fixed message packet which does not
change consequently missing data can be re constructed by eye over
several periods of reception just like QRSS.
This Capture
http://i221.photobucket.com/albums/dd243/radiotalk/green-led-rev.jpg
shows some WSPR coded as Morse in a form you may not be able to read
because you have not learned the skill, followed by WSPR which you
also most likely can't read because you haven't learned the skill.
Both sent without the aid of a PC.

Rtty is a sophisticated mode because it
can be read at Level One from a tape or screen or Level 2
where it can be printed out on a tape or screen. The Data
modes current at presentd although visible on screen/waterfall
cannot be read directly and NEED a decode to obtain the
information sent
therefore
if you are not getting a print out of rtty
you can read the elements from the waterfall and get the
information.

WSPR and VLF
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..

Yes 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

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.
