[SADXA] 1A0C

[Jim Wysocki]

Bill, I came back to 40m and listened for them about 30 minutes after 
Carl's QSO.  They were a few db weaker but still good copy.

Yes, transmitting back into the darkness helped boost their signals to 
us quite a bit, and vice versa for we who were using the same signal 
path to them.
