Bob & All: Interesting observation on 73~74 kHz with XRS/4 because I'm only 
a few hundred miles from XRS/4 and DK7FC suddenly appeared around 0105~0110 
UTC on 136.172. So whatever "Swiss Cheese" iono propagation was happening 
occured slightly later in western Pennsylvania as well in the 136 kHz 
window.   I can listen on two LF freqs at the same time, so perhaps some 
dedicated rx on 73~74 and 136~137 at the same time may yield some usful 
propagation insights.....  Problem on this end is Bob is so dam loud 
here....time for the +17dBm mixer I suppose.   73,  Mike wa3tts.
