Friends,

At about 04:30, KI0LE picked up the weak signals again from QRSS60, 100 Watt, VY1JA during a period of apparently maximum signal strength just before the XES signal died. This is much like what happens on HF and MF. The signals apparently become strongest just before they disappear.

As long as the beaconing is going on 24/7 for the experiment here, the outgoing propagation is watched here by using Rapido on KI0LE and VE7TIL grabbers. This is proving to be an excellent tool for experiment records and I would like to provide the option for others to check for their signals at VY1JA in return.

Has anyone found an "inexpensive", yet effective way to null out the transmitted LF signal while receiving on another antenna? Links, articles, white papers?

J.
