Amateur Radio has many aspects. If it only were to exchange a few 
details like a callsign and a report on LF, then nobody would use 
this reflector. There is no difference between LF-work, EME and 
meteor scatter or AO-40-operation: all need both, operator practice 
and technical knowledge and the fascination to get something work. 

If something has been used for years, it could die very fast. That  
happened this year in the meteor scatter area.  Joe Taylor published 
his "WeakSignal by K1JT" program (WSJT) this year.  My automatically 
written log on 144.370 MHz obtained with an omnidirectional antenna 
counted 24 heard DXCC countries on last sunday, all using FSK441.
