QRP on 10 es 6 m works well because of antenna
dimentions and ERP but is a different ball game on LF where high
power is needed to generate a sensible ERP to get beyond the back yard.
Activity this past two days on 10 and 6 m is non stop
in QSO mode with some vy strong sigals from around EU and beyond on both
CW and SSB. Cannot say I heard much Data. There is the odd Country Beacon in CW
mode but the band is not swamped with individual beacons and pse QSL via Email
freaks.

It must have been fun when CW activity on 136/500kHz
was high. However, lack of CW activity does not mean lack of activity
per se. Most nights (and some days) I see QRSS or WSPR activity on
these bands.
There was a suggestion made a few weeks ago for
mode specific activity nights on 136kHz. May be this is a way to focus on
certain modes? It certainly works on 2m and 70cm with activity nights when
people know SSB/CW QSOs are very likely.
I agree that spreading
activity too thinly can be an issue: if a few of us are on WSPR, others on
QRSS and others on CW, and all at odd times, then the chances of
contacts/reports are reduced.
As QRP man I'm in no position to say what
goes on the 136/500kHz - this must be a decision made by you serious QRO
operators - but mode specific activity nights/days does sound like a good
idea.
Now back to 6m/10m QRP CW.....

The procedure in the past was to use CW anywhere on the 137 khz
band and
then Tune the band after a CQ for a reply, this is what I do
because
everybody has their antenna resonated on a different frequency
and it avoids
working off resonance, which is not recommended with HI Q
antenna systems
and high power.
136.5 khz was used by those with the
Ropex TX xtal controlled on that
frequency, then they would tune the band
for replies for those with VFO ctl,
also avoid QRM.
In the beginning
and for some years the only mode used was CW then QRS was
introduced and
later Beacons.
Since the introduction of QRS and Beacons the LF
population has dropped from
over 30 active countries and over 100 radio
operators to virtually Nil at
present.
Data appliance operator
activity more recently does not help either.
What used to be a regularily
used band daily for cw activity is now a wast
of time and 500 MF has gone
the same way.
Another factor is the QRP aspect which means the band is
now a parochial
affair for local activity, mostly Beacons or Data whereas
it was once an
International band with regular world wide QSO'S even in
the summer time.
These are the facts
