HI All: Just an FYI as I see DK7FC active on his LF grabber on 136.172 DFCW. No trace of Stefan's signal yet as sundown occurring. Also noticed some substantial carrier lines below MP and some audible ker-chunking going on. I thought it may have been LORAN-C but nothing running at 100.0kHz, not sure what's up...... 73, Mike wa3tts
