If you can only produce a dot or a less and no ID
then it is time to QRO so that your transmission can be seen properly.
Do not depend on an ID based on Frequency
accuracy, it leads to gueswork.
And long slow transmissions with QSB is a
waste of time and meaningless, ie broken up dashes and impossible to
ID
This has all been discussed before and concluded that slow
prolonged dases/transmissions are useless.
With some effort and suitable power short sharp
transmissions are preferable.
It seems to me in recent times we are covering the same
old ground and making little or no headway.
So far I have heard/seen ONE German and one Austrian stn
on VLF, where are all the others that were so keen to TX.

Congratulations to Kuni and Toni, and thanks Mike
for sorting out the relevant screenshots.
Yes faster modes may give a powerful station
a better chance to get a complete message across. Already on Monday
evening, dots from HE3OM have definitely been identified on the JA7NI grabber
while it was running in 84 mHz "QRSS-10" resolution.
But for the likes of ourselves who are able
to produce a marginal SNR at best, I think the only option
is trying to produce a few traces at 90 seconds or slower
modes.
Best regards, and good luck to all,
Markus (DF6NM)

Last night HE3OM put a
good signal into JA7NI's grabber at JA dawn..
UA4WPF can also be seen, but
much weaker than previously. See
attached.
Also attached is the
same time on RN3AGC's grabber which shows that
DF6NM and myself were also
calling, but we could not compete with
HE3OM's ERP which I estimate as
15-20dB up on us.
The JA picture also supports my theory that QRS120 is
not a practical
speed for real DX. There are long periods where the signal
is well
above the noise, but QSB prevents the whole callsign being
received.
At that strength, QRS30 would probably have still been viable
and
allowed a couple of full calls to be read.
Congratulations to
HE3OM on what may be an amateur world record on
136, though with an
estimated ERP much bigger than most amateurs have
available.
