Thanks for the Info Dave, at least i know what i'm looking for now..  so 
much stuff on LF u dont know if it's data signals or qrm...hi

ok on the activity, as i noticed there was mostly posts for 500KHz... i 
tuned to 502.5? earlier with long wire and saw a cw signal but it 
stopped before i had time to id so maybe someone was active and i just 
missed them... maybe around 19:20 today.

I'm seeing 138.83 about 35dB above noise in SpectrumLab and have put a 
wide band mmic amp in front of my IC-706 and it now has come to life!  
138.83 is about S8 with lots of breakthrough etc...need to make a simple 
filter.

I think i will hang around for a few active stations sometime to check 
things out, a signal would be nice but no need to go out of your way for 
it!  i'l try optimise with 138.8 signal then listen a bit more.

well i'l do a bit more work then come back...
