You really know how to make Friends with comments like
STONE AGE .
Seems to me that the ones dragging there knuckles on
the ground are those who fail to accept the fact that
there are other things but using the ham bands for
E-MAIL
When you start to act like others exist and they have
rights too try again
BTW .
I DON'T DO CODE . but have a open mind for thoes
who do ...

Regarding the continuing vocal disagreement (and
flame-wars) between the
live chat operators, Morse operators, and the
BBS/Winlink or ALE network operators:
Two HF bands are discussed below as examples of
possible ongoing
evolution throughout the amateur radio service's
spectrum allocations
There is some history that relates to the popularity
and use of various
non-Morse
operations prior to year 1995, and now . Non-Morse
operation in the past
was only live keyboard to keyboard mode until the
innovative spirit of
amateur
radio operators realized the value of ARQ modes for
error-free message
handling, starting first with HF Packet forwarding.
Back in the stone age of amateur radio, and before
the advent of
sound-card modes,
the prevailing location for Amtor and pactor was
specifically between
14070 and 14080, with 14080 to 14099 being for RTTY
operations.
Back in this Stone age, 40 meter Amtor/pactor was
allocated to the
7070 to 7080 KHz segment, and RTTY operations from
7080 to 7099 KHz
As time passed, fewer individual stations were using
Amtor/pactor/G-tor for
live-chat, which left primarily the pactor stations
being used for BBS
mailboxes
and message forwarding ... This change in usage was
primarily due to the
preference of radio amateurs to adopt less-costly
methods of digital
communications
that did not require the investment of $300 or more
for multi-mode TNC's
of the time such as the early versions of the
Kantronics KAM; MFJ-1278, and
AEA PK-232 hardware modems.
A solution to the interference problem between ARQ
modes and widely popular
sound-card, and other types of Live chat modes
using data
communications
would be to migrate live-chat operations farther
down the band, such as
7050 to 7070 , and 14050 to 14070
Due to the elimination of Morse code as a
requirement for an amateur radio
license, it is likely in the future that the
current use of the
RTTY/DATA
bands would be inverted in usage, i.e. Morse code
operations would
*primarily*
be in a more narrowly-defined sub band, while data
modes would exist over a
much
larger band segment in each amateur radio band than
Morse operations ...
On a legal basis, Morse operations would continue to
have access to the
full allocation of each amateur radio HF band...
This may ruffle the feathers of the old-timers,
however Morse code will
still be of major importance as a very simple and
manual mode of
communications
when more robust modes are not available.. Morse
code will also remain
important
in the future as a part of living history ...
It is likely in the future that, for example, Morse
operations may be in the
14000 to 14050 segment, and data modes between 14050
and 14099
and 14101 to 14120 KHz, while Morse operations on 40
meters may
be between 7000 to 7050Khz with RTTY/data between
7050 and 7150KHz.
Message forwarding operations would likely be toward
the upper-portions of
the
RTTY/DATA bands, while manual, Live chat
operations would be farther down
in frequency with respect to the BBS/forwarding
stations
(whether they are Winlink or other modes yet to be
developed)
Flame on this idea if you wish, however robust
live-chat sound-card modes,
ARQ messaging modes, and Automatic Link
Establishment (ALE)
modes will all gain increased popularity,
acceptance, and adoption because
of their more efficient and reliable communication
capabilities as compared
to
manual and non-keyboard modes ..
