Dear Laurie, John, LF Group,

Well ... I leave town for a couple of days and it all starts happening! 
Assuming Laurie and John's reports check out OK, this will be 
something quite extraordinary. Given the noise level on 73k, and 
the reduced ERP available on the band, propagation losses would 
have to be very much less than on 136k - I wonder what the 
pundits make of this? 

I saw Laurie's signal when checking 73 kHz last night, without 
having read the E-mails on the topic from the previous couple of 
days, so it took quite a while to figure out what it was - the 
frequency shift was very small, only about 0.06Hz. Laurie has 
probably the strongest signal on 73k at the moment, about 579 with 
me, but much lower SNR than on 136kHz. I would be very 
interested to hear from John what the band conditions are like in 
Canada - here, the QRN seems to drown out even the Rugby 
sidebands at night, although it can still be quite quiet at times 
during the day. 

Cheers, Jim Moritz
