It is exactly my point that there is no phase shift associated with standing- wave current in a coil or in a wire so it CANNOT be used to "measure" phase shift. On the other hand, the standing wave, which is nothing more than the superposition of the forward and reflected waves, easily demonstrates the effect the propagation delay has on the forward and reflected waves. There is NO phase information in the current used for the W8JI and W7EL measurements. That certainly can't be said about your measurements. Perhaps that's why you're so reluctant to make any? :-) They both apparently thought they were measuring traveling-wave currents when the currents were actually overwhelmingly standing-wave currents. Don't flatter yourself, Cecil. You're not that much smarter than everybody else in the room. 73, ac6xg |

But the phase information in the forward and reflected waves does not appear as phase information in the standing wave. The forward and reflected phase information appears in the standing-wave amplitude. That is another error that W8JI and W7EL made. The different amplitudes of standing- wave current at each end of a coil is NOT caused by losses and radiation. It is caused by superposition of the forward and reflected waves. It would still happen if there was zero losses and zero radiation. Don't flatter yourself, Cecil. You're not that much smarter than everybody else in the room. Not smarter - just more observant. I saw something that nobody else was looking for. It is only closed minds that are the problem now. -- 73, Cecil http://www.w5dxp.com |

A perspective which apparently shifts depending on which side of the room you happen to be standing. 73, ac6xg |

My mind is open, Jim, but since you refuse to enter into a technical discussion, I am not likely to change mine. -- 73, Cecil http://www.w5dxp.com |

I see Cecil is still using misdirection, that old but reliable trick of
illusionists, to try and divert attention away from the flaws in his imaginative theories. Have patience. Even he will tire of it after a while, and get back to his waves of average power that bounce off each other when they collide.

This ad hominem attack brought to you by the person who has asserted that he used a current with unchanging phase to measure the phase shift through a loading coil and that he stands by that measurement. Even he will tire of it after a while, and get back to his waves of average power that bounce off each other when they collide. Posting a statement that you know is false is not ethical. EM waves do have energy which averaged over a number of cycles is called irradiance in optics. That energy passing a fixed measurement point is the average power. And the waves don't bounce off each other - they superpose, sometimes interfere, and sometimes cancel. -- 73, Cecil http://www.w5dxp.com |
