Stefan es Co
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 avoi= ds
working off resonance, which is not recommended with HI Q antenna systems<= br> 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 ct= l,
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 fr= om
over 30 active countries and over 100 radio operators to virtually Nil at<= br> 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 ti= me.
These are the facts
