Are you sure this wasn't a lid ? I didn't think they were going to get
set up for about another 3 days. Wes Stewart wrote: High line noise here but worked him fairly easily on 20 meters. |

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 |

I shudder to think what it sounds like on SSB. The online log search is working this morning -- hopefully that means the weather lifted & allowed the delivery of the rest of the supplies.

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 |

Dear Doug: please see comment below...

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! I am located well out in the country in the Lower Peninsula of Michigan. (A troll because I am below The Bridge.) The nearest large city is Flint. I had the same experience with the last VU4 group (December 2004). I heard them well enough to be almost certain of call signs about twice for a few tens of seconds. I have a quiet location - well, most of the time, P-noise can be a major problem - and one can take to the bank that they (VU4) were weak. I was invited to give a paper in April, but I am not in shape to do such a thing in person. Several other members of my department are also radio amateurs, but they too are not able to go. In this modern age, I will present electronically. We all hope that those who attend with licenses and antennas will be effective with the path our way right through the magnetic pole. Have you heard of a group with a track-record that proposes to attend? 73 Mac N8TT snip -- Doug Smith W9WI Pleasant View (Nashville), TN EM66 http://www.w9wi.com |
