Content preview: Further to Alan's posts, some thoughts on the earlier 72 kHz TA reception from December, 2002. TA signals from G3AQC and G3LDO (among others) on 2200 meters had been regularly copied in the eastern U.S. This was all done at QRSS60-120 data rates. The end of the 72 kHz NOV's in the UK was approaching, and Laurie and Peter began transmitting regularly at 72.4 KHz, with Laurie using something close to DFCW240. Nothing was reported from over here until the evening of 6 December 2002, when I put the receiver on after dinner, and saw a strong signal where none had been in the previous week. I sent out emails, and over the course of the evening, the only U.S. copy of Laurie was from Jay, W1VD and myself. Watchers further south and west reported nothing. We believe that Laurie signed off around 0130...in any case, the copy ceased.

This suggests that Alan's famous "leaky reservoir" was fairly full, but that LF conditions had not been depressed by a recent CME. Speculation at the time was that we caught a period where the signal "hop" landed in this part of the U.S. I believe this would have been a 3-hop path (Alan will correct me), but this might have been a time where the 2nd and 3rd hops happened to end in phase over here. Jay and I are 100 km apart, pretty close for this sort of thing, but the unsuccessful listeners were considerably farther away. This record may fall with the use of higher power, but Alan is definitely correct about the effectiveness of Laurie's unusual antenna.
