It seems every time that CW is mentioned as an efficient mode of
communications, especially on LF when one has to consider bandwidth
because we only have about 2khz available, some seem to get upset and
reply in a derogatory manner.
There is no other mode currently in use that suits radio amateur type
activity when considering bandwidth and transfer of information.
Commercial activity is entirely different where large amounts of
through traffic is essential and the users employ appliance
operators, with basic skills.
I have been involved over the years with FDM and TDM systems and
other associated modes and these are fine for commercial applications
but not suitable for the radio amateur with only a signal report
exchange.
For those enquiring. I started computer technology in the days when
one had to build/assemble their own computer and write the
appropriate software. I also started amateur radio when the only
option was self build, especially the TX or modify ex govt
equipment.The GPO licence then was for CW only for the first 12
months and phone was only permitted after proving that the licencee
had worked a minimum of 200 successful CW QSO'S.
How things have changed. Some one on here recently remarked that the
most difficult part of getting a radio amateur licence at present was
being able to fill in the appropriate FORMS !!!!!!!!!

The morse test was at a speed of 25 wpm or 30 wpm for the extra class
and the duration of the test was for 15 minutes non stop. The
technical papers examinations required at least 60 percent pass but
most achieved between 70 - 90 percent.
To day the pass mark required is around 30 percent at university.
These statistics might upset even more people !!
