It readily explains how poorly the gejoken experiment started. Let's see how many yuks it will get through conventional issues I used toroidal pickups at the current sample points and viewed the current waveforms on a 100 MHz dual-trace oscilloscope. No mention of make, no readings, no pretense at discussion of those things that contribute to error (and, as such, no need for Cecil to apologize for being wrong until he is painted into his usual corner). So, from this sloppiness called anyone performs that experiment in a valid manner, I suppose I have to fill in the blanks and watch Cecil sputter that it wasn't like that at ALL!!! The cartoonist is most comfortable in simple things, certainly; but measurement is best left to professionals. measure a ~25 nS delay which is the same as a 40 MHz event, but in some "100 MHz" scopes, and depending upon a myriad of settings (anyone practiced in the art would realize how many), signal amplitude being one; that same BW can tumble to 20 MHz to the unsuspecting user's surprise (Cecil can now react in mock surprised shock). With a roll-off of 3dB per octave (another concept that is foreign to digital engineers, such is Cecil's legacy), phase measurement errors begin to run away. We don't even get the Sunday comics form of math! OK, so measure a ~25 nS delay is so much of a hodge-podge, a place marker, a spit into the wind, something summoned up for the unwashed so the author could bask in their awe-shucks. If we were to simply accept it (GASP!), what does it say of the delay introduction of the toroidal pickups at the current sample points More magik happens here no doubt. I won't ask Cecil what his data is for these items because he doesn't have any (at least until he rummages up the dutch courage to fake it). And what about the phase issues of the 4000 Ohm resistor (which conveniently snubs what might be found in the rest of the antenna now long discarded such that this becomes an onanistic exercise)? Again, no point in asking for data that doesn't exist (you can't even fake it). Magik abounds because Cecil's best work is cartoonistry, not science, and certainly not rocket science. So, a very quick enumeration of points any experimenter would have come into the discussion with, rather than trailing behind like a dancing bear with blisters. But I like gejoken experiments, and Cecil's clowning offers the dovetail to Art's when he isn't here complaining about the nails in his hands. I would give this, maybe, 3 yuks. 73's Richard Clark, KB7QHC |

Oh yeah, I almost forgot your earlier postings. Only you are capable of measurements. Everyone else in the world sucks.

Oh yeah, I almost forgot your earlier postings. Almost remembering is equally handicapped. Only you are capable of measurements. Hardly, more the point is noting those who are not capable and clearly demonstrate their ineptitude. I've ushered you through more than a few of these to then hear your excuses of age, infirmity, poor reading, and so on. You have the unfortunate circumstance of having inhabited a binary world where there are only two answers - both resolvable only to one place in the absence of noise. Ours is an analog world that copes with noise and error, and what counts in life is how much error. I enumerated several sources, you respond to none (a binary choice). You allude to my capability for measurement as I have measured the error of such scopes as yours and fixed them. You are simply hoping your scope is within its range of capability and we have yet to hear any reports of readings that would either confirm or deny your claim. Well, if you don't provide the data, no one can call you on a failure, right? Another binary choice that struggles for breath in an analog world. Let's look at the -3dB roll-off point and I ask you, how many degrees of slippage does it represent? 0 and 1 are not competent answers. Everyone else in the world sucks. A typical binary perspective and you are glad to force the choice. The analog equivalent is some"one" else in the world sucks. It could be parts-per-billion/million/thousand/hundred - but we can both agree that rhetorically you've scored your point. This from the person who asserts that the reflections from non-reflective glass are brighter than the surface of the sun. From your data, from your math, and from your argument. You couldn't account for the missing energy, so you swept it under the prayer rug with a mystical chant and abridged readings from your Psalter. Choose another topic for the same outcome, you've suffered many such technical comparisons. |

Measuring the delay of a 4 MHz RF signal through a device is hardly any different from measuring the delay of a 4 MHz digital square wave. Measuring the time from one zero-crossing to another is virtually a no-brainer. It doesn't take much of a setup to detect the difference between 25nS for the traveling wave current and w8ji's measured 3 nS or w7el's measured undetectabe (faster than light?) phase difference using the total current in a standing wave antenna which is 90% standing wave current. Please design and run your own perfect experiment for determining the delay of a traveling wave through a 75m bugcatcher coil. I guarantee, if you perform it in a valid manner, it will agree qualitatively with my experiment. What is it about the phase shift in 90 degrees of monopole that you don't understand? ************************************************** ** EZNEC+ ver. 4.0 thin-wire 1/4WL vertical 4/16/2009 6:33:09 AM --------------- CURRENT DATA --------------- Frequency = 7.29 MHz Wire No. 1: Segment Conn Magnitude (A.)

There was no missing energy. Your superposition of power was the problem. A three watt wave does not destructively interfere with a two watt wave to obtain a one watt result. That was explained to you years ago when you first made that conceptual error. The correct power merging equation must contain an interference term unless the two interfering waves are 90 degrees out of phase. Hint: 3w + 2w - 2*SQRT(3w*2w) = 0.101 watts There's no missing energy! -- 73, Cecil, IEEE, OOTC, http://www.w5dxp.com |

Measuring the delay of a 4 MHz RF signal through a device This is all the naive hope of absolute faith (a binary choice) in an instrument where you cannot distinguish between capability and desire. Let's face it. The enumeration of readings, the descriptions of all elements in full is very trivial and within the grasp of any ordinary bench tech. That it is so wholly missing from your discussion means that its revelation would expose a major error of design, or would reveal you are not practiced in the art of analog engineering. You've had time enough to back-fill your virtual notebook with these details of normal procedure. Their sudden arrival in successive discussion won't have much authenticity. What is it about the phase shift in 90 degrees of monopole that you don't understand? You are more flummoxed by the simpler problem of your own instrument's introduction of phase error at the -3dB point. If you cannot reconcile that at the bench, then this navel gazing problem of yours is sterile and pointless. From your data, from your math, and from your argument. There was no missing energy. More faith and hoping which culminates in the absurd: A three watt wave This arrives from your fog of memory, a poor device I warned you about in the last post. As I pointed out, same outcome. Is your apology of age, infirmity, or sloughing accuracy for speed next? |

I have a new respect for those that hunt for relics with scrip on it and try to decifer the meaning of such a wierd collection of shapes and scrawls. Obviously a lot of work and fraustration which is nothing compared to the disapointment of finally realising the content of the work under study. Line after line of unrelating words with no connections between the lines which is obviously that of a child that faking an adult posture. Put yourself into the bottle you just finished and hurl yourself out to sea for the ages. |

I used to have a fuzz-phrase generator card. It had three columns of ten words each. One could think up any three digit number and then read the three word fuzz-phrase off the card. 123 might result in: flummoxed simpler problem 343 might be: navel gazing problem Richard has obviously written a similar computer program except it seems to have ten columns of 100 words each. -- 73, Cecil, IEEE, OOTC, http://www.w5dxp.com |

In your case, they usually begin with trying to make sense of your Tudor grammar and spelling (probably why you spit on that up and coming Shakespeare and his new-fangled writing). |
