Worked N8UZE and W4NTI this past weekend. Where were the rest of you? I
coulda used the Q's! I think the ionosphere was tilted because there was a LOT of one way propagation. Maybe someone put diodes in my transmission lines? ô¿ô 73, de Hans, K0HB -- Help support youth involved in Amateur Radio. http://www.mnyarc.org http://www.k0bsa.org |

I think the ionosphere was tilted because there was a LOT of one way propagation. Maybe someone put diodes in my transmission lines? I've had that happen fairly often as well. My rig's receiver seems to "hear further" than my rigs transmitter can "shout". But I heard a local ham also not get heard by some DX that didn't hear me. Probably a few too many contesters QRMing each other. It happens, no malice assumed or expected. |

Short skip was really loud on 20 on Saturday. You were slammin in here.
I use a vertical loop at about 45 feet to the top. Really does well on NVIS stuff. Great hearing you. Don't think I heard Dee. Dan/W4NTI "KØHB" wrote in message ink.net...

North/South paths were excellent, but East/West paths were non-symmetrical, which suggests a tilted ionosphere. The further north you were, the more exaggerated the effect was. I was hearing the W7/VE7's weak and watery, but they reported my signal as huge. Meanwhile W1/VE1's who I had 20-over were CQ'ing in my face. Can't wait for CQWWCW!!! Maybe the freckles-del-Sol will be more cooperative. 73, de Hans, K0HB |

I thought light (here radio waves) would propagate equally as well going as well as coming back. Like "If you can see my face I also can see your face". |

Imagine that the ionosphere is an imperfect mirror which reflects signals best when they arrive at some specific angle, and reflects less well when the signals do not arrive at that optimum angle. Now imagine that the "mirror" is tilted to favor one direction (your signals arrive at mirror at the right angle, but mine arrive at a more oblique angle and are consequently refracted more than reflected, and at the same time the reflection angle is such that my signals pass "over your head" to a more distant point. ). I will hear you well, but my signal will be attenuated. From my end the skip appears "short", but from your end the skip will appear "long". Only when the mirror is equidistant between us and when it is "flat" will the path be symmetrical and relative signal strengths reciprocal. 73, de Hans, K0HB |

Was tempted to make a wise remark like "Hey, thanks for the nice connection!", but was struggling for points at that time, so I didn't slow down for chit-chat. Sorry I didn't recognize it was you. 73, de Hans, K0HB |

Our goal was the clean sweep but we just didn't get the propagation. I heard the PAC section but to weak for me to be able to get through the pile up and we never did hear NT from here. We ended up 10 sections short. Last year, when we weren't even trying we were only 3 sections short. Dee D. Flint, N8UZE |

Somehow I would have thought that light (radio waves) could travel either direction on the same exact path. And that attenuation either way would be identical. Same for the same set of multiple paths. But it's been years since Physics class...... |

And if you spend any time on HF during disturbed solar condx, you will receive many vivid demonstrations of non-reciprocal/non-symmetrical propagation paths. 73, de Hans, K0HB -- There is no voodoo or magic associated with RF propagation. There are several perfectly sound technical reasons why it is beneficial to occasionally sacrifice a goat in your antenna field. |

There were times that when I beamed over the SOUTH POLE it was better than the direct path. I'm not sure it should be called 'one way skip'. But for lack of a better term..hi. Dan/W4NTI |

Maybe another time. Dee D. Flint, N8UZE Yep, I wasn't feeling too well on Saturday. My other op couldn't make it. So I did mostly search and pounce on Saturday. On Sunday towards the mid day I started CQing. Managed 434 qso's, 76 out of 80 sections. Not good. But considering it all...hi. See ya down the log. Dan/W4NTI |

There were times that when I beamed over the SOUTH POLE it was better than the direct path. I'm not sure it should be called 'one way skip'. But for lack of a better term..hi. That's "skew path" propagation. It's actually pretty common, but you don't notice it so much when we're high in the sunspot cycle curve. At solar-flux minimum, however, it becomes more noticed because you are more likely to "tweak" your beam azimuth to wring that last little half-dB of signal strength. Also, it seems more prevalent on the lower bands, below 10MHz, which otherwise can get hammered by auroral zone absorption. From here in the midwest, the skew path to EU is toward western Africa, almost 45 degrees of the normal azimuth. During CQWW I often work from W0AIH's superstation ( http://www.qth.com/w0aih/ ), and use the Africa rhombic to work Europe --- it's non-intuitive, but you can really roll up a score on 80M! 73, de Hans, K0HB |

Same for the same set of multiple paths. But it's been years since Physics class...... As W4NTI points out, the ionosphere isn't really a reflector - it's a refractor. The waves are bent, not bounced. When the ionosphere is stable and uniform, it behaves *like* a mirror, and the 2 way reciprocity thing works well. But when it's tilted, twisted or otherwise distorted, the refraction in one direction may be different than in the opposite direction. As an analogy, think of "one way" mirrors in optics and how they behave under the right conditions. 73 de Jim, N2EY "If it happens, it must be possible" 73 de Jim, N2EY |
