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 !!!!!!!!!
de G3KEV (retired RADIO and Electronics
Officer, Aeronautical, Marine and Fixed Services)
for those who do not know what that
means. Licensed to operate from aircraft, ships, fixed
ground stations aeronautical or marine and
government establishments.
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 !!
