[Lowfer] Interesting 74.321 KHz results in Mechanicsburg, PA. FN10LE

[Dick Goodman]

Gang,
 
    Please find a link to four (4) plots that I ran on the 74 KHz
transmissions on 7 & 8 January. What I found the most interesting is that on
the afternoon of January 8, after being totally faded out for several hours,
XRS4 popped back in twice for about a minute each time. There was a very
recent solar flare over the last day, could that have caused this or is what
I'm seeing a normal propagation effect?
