Roger I have used just about every digital mode
invented. I had a BBS for years GB7KEV main line East coast relay and delivery
system.
I had gateways vhf/uhf to HF and used PACKET,
AMTOR, PACTOR and MSYS software, as well I used RTTY and PSK and in more recent
times I have tried all the so called innovative data modes and I am
not impressed when it comes to real time QSO activity.
I learned morse at an early age and how to
speak therefore I prefer to use CW and SSB and the bulk of radio
amateurs seem to think likewise because the amateur bands are full of CW
and SSB acty with only a minority using data modes by
comparison. One non morse mode that seems popular is RTTY. I learned
to touch type also at an early age and find this useful when I divert from morse
the odd time and useful for emails on the computer keyboard.
From my experience I find CW the most appropriate
mode for LF/MF because of propagation characteristics on these bands but I am
sure other non morse modes would be suitable on the HF bands.
Thanks for your input and point of
view.

Dear Mal,
Both CW and digital modes have their place and
their merits. Many here enjoy using both; certainly I do.
73s and see you on CW
sometime.

Who
are the 'us guys' the majority of LF/MF operators are on CW, have a look at
the list of operators that I sent yesterday. Jim you appear the odd time and
your CW has got worse I expect its WSPR for you or nothing. By all means
ignore my observations but I get a lot of positive feedback from experienced
radio amateurs and professionals in the electronics field and Nonsense most
of the time from data Appliance Operators.
CW requires operator skill but
machine generated data modes only needs an observer. Watch the kettle boil
operator.
Commercial operators use data modes to shift large amounts of
information, hardly a requirement for a radio amateur exchanging name and
signal strength. CW is ideally suited for short real time exchanges between
radio amateurs.

Dear
Roger, LF Group,
Please bear in mind that G3KEV does not speak for
"us guys", only himself.
Over the years we have learned to ignore him
most of the time - if we took
much notice, we would all have given up a
long time ago.
If you look in the WSPR on-line database specifying
the band as "LF/VLF",
you will see that there has been quite a lot of
WSPR activity over the last
year on 136k and 500k, which has been one
of the more successful digital
modes in this part of the spectrum. The
points you make regarding narrow
bandwidth and low power are certainly
useful at LF/MF. The summer months are
usually rather lacking in
activity due to the short nights and high QRN, but
activity, no doubt
including WSPR, will be picking up soon as we get
into
autumn.
The M0BMU LF/MF station is currently QRT due to a
recent visit from
relatives - all those pretty coloured wires and
3-year-olds don't really
mix! It will probably be put back together
this weekend though, so if you
are interested in trying WSPR on 136k or
500k, let me know.
Cheers, Jim Moritz

...But it's *not* my place to tell you guys how to
use the LF bands so with
this,
I'll leave you to it and get back on 10m WSPR, CW and SSB.
Good
luck
with whatever modes you
enjoy.
