The only authenctic QSO's on LF are those conducted in real time CW and
possibly some at QRS2 or 3.
The majority of other claimed successes are GUESSWORK or IMAGINATION.
Last year during the ZL tx tests I saw some bright traces on the designated
frequency at the time of transmission but I would not claim a hit because
there was no proof of part callsign but I gather recently someone in ZL is
claiming a success under the same circumstances. ie saw a brightup on the
freq used by a G3 stn.
Sometimes there appears to be coherent bits of signal observed while
monitoring LF but it is just a burst of a particular type of noise.
My story to the world is treat with suspicion what anyone tells your about
their achievements on LF.
The trouble is some people would believe anything !!
