Are you sure this wasn't a lid ? I didn't think they were going to get set up for about another 3 days. On 17 they're peaking the right direction. http://www.peterone.com/updates.htm says they're on the island and expected to be on the air as of 0400 UTC today. (i.e. last night USA time) There's no further news but I'm sure updating the website is pretty low on their priority list right nowgrin! On a very vaguely related subject... I note in the last hour, three different 3Y calls have been spotted on DX Summit... Either someone out there isn't paying attention, or there are in fact a couple of "Slims" out there. To be honest I suspect the former... -- Doug Smith W9WI Pleasant View (Nashville), TN EM66 http://www.w9wi.com Ham stuff for sale: http://www.w9wi.com/articles/4sale.htm |

Dear Doug: Interesting observations.
The intentional interference has been frequent and often effective - if that is the right word. On various of their frequencies, the use of a continuous carrier that is within 2 Hz of 3Y0X's frequency is heard. It appears not to be from NA or SA. It would be interesting, though little more, to hear a psychologist's analysis of what causes persons deliberately to cause interference. Miraculously, I heard 3Y0X on 8o meters CW last night and appear to have worked them. I have gone over the propagation predictions again that suggest the unlikelihood of such a contact. I will wait for the geophysical parameters to be posed and look again. However, my guess is it was a combination of about 100 Hz effective BW, exceptionally low noise at both ends, a vertical reflecting off of salt water at their end, a tall antenna at this end, and (most important of all) the use of CW. I also heard them very weakly on 24900 about Noon. The place with the worst propagation path from here is VU4. Guys at Peter I have shown how to do it. Only criticism I have is that they could profit from providing us with some idea of how long they will work only (fill in the blank). To say EU for one hour and then Region 2 for an hour and then Region 3 for half an hour - or some such - would benefit many. 73 Mac N8TT -- J. Mc Laughlin; Michigan U.S.A.

It would be interesting, though little more, to hear a psychologist's analysis of what causes persons deliberately to cause interference. I landed another QSO on 15 CW this afternoon. Intentional QRM was nearly non-existant and general behavior good but not perfect. Miraculously, I heard 3Y0X on 8o meters CW last night and appear to have worked them. I have gone over the propagation predictions again that suggest the unlikelihood of such a contact. I will wait for the geophysical parameters to be posed and look again.

I also heard them very weakly on 24900 about Noon. I've learned not to put too horribly much credence in propagation predictions on polar paths. Reality seems to have a way of trumping theorygrin. I also heard them weakly on 24900 about the same time - not strong enough to work. It almost appeared they had better propagation to California than they did to here. They were fair on 15 SSB at the same time (and the pileup was surprisingly well-behaved) but they announced an operator change before I could work them & the new op never showed up. (unless he was the one who took them to CW!) The place with the worst propagation path from here is VU4. Agreed. (not sure where in 8-land you are but I'm probably not much more than 1000km from your QTH) When the VU4 was on a bit over a year ago, I heard them an entire once, and again not strong enough to work. I hear there's going to be an Indian national amateur radio convention on VU4 later this year & operations will be permitted. Hopefully propagation will cooperate! Guys at Peter I have shown how to do it. Only criticism I have is that they could profit from providing us with some idea of how long they will work only (fill in the blank). To say EU for one hour and then Region 2 for an hour and then Region 3 for half an hour - or some such - would benefit many. I might guess they figure that dynamically based on propagation & other duties. But that's just a guess. -- Doug Smith W9WI Pleasant View (Nashville), TN EM66 http://www.w9wi.com Ham stuff for sale: http://www.w9wi.com/articles/4sale.htm |

Any chance you guys that have worked them or even heard them could put it on
here so the rest of the folks could stand a chance. Seems every time I get on where there supposed to be the signals are poor to say the least. I am equiped with a TA-33SR on 20-10 with 500 W amp. Can do 40 plus 30 and WARC with my Delta loop for 40 with L/L feed. 160 with a "U". Dan/W4NTI |

They are running veticals on 30 and 40, wire on 80, and steppers on 10, 15, and 20. last night (Saturday) the pile was as wide as the band, for the most part. But he was about 559 on 30, 40, and 80 cw for about 5 house each. With that many people calling him, it is pot luck anyway. I managed to work him on 30 Mtrs at 0639 last night. That seemed to be the best band because there was fewe lids and less QRM on his frequency. Bu,t I really need him on 40 or 80 for five band. I will be there again tonight. Win |

Seems every time I get on where there supposed to be the signals are poor to say the least. They've been plenty loud on 30m (I forget where - 10103?) and 40m (7023) fairly often. Just keep a watch on those frequencies. Unfortunately the pileup behavior has also been worst on those frequencies. They were a lot weaker (but still well within the capability of your station) on 15 and 17m, where the piles were a lot better-behaved. 21023 may be worth staking out. I heard them here on 12 meters but nowhere near well enough to work. -- Doug Smith W9WI Pleasant View (Nashville), TN EM66 http://www.w9wi.com Ham stuff for sale: http://www.w9wi.com/articles/4sale.htm |
