Mike: RRR. I recall seeing similar results when listening for DK7FC DFCW 
signal on 136.172 kHz. I would get similar light traces and then when some 
enhancement in propagation occurred Stefan's signal would capture above the 
background noise level.  Also encouraging for me given the recent episode 
with Thor's Hammer (close lightning hit)... Thanks for taking the time to 
make the antenna change.
