A select few our legally assigned frequency bands takes us takes us we "lurkers" we were to take we are Most of us we need Most of us We all we have our "ptical We all Insecure, aren't "we?" I believe that the extant wave versus particle "paradox" is irrelant to my following comments, assertions and questions. Rolling up the rug before it is snapped? Also I believe that the dividing line between transient and steady state phenomena may be considered to be insignificant and so considered to be irrelevant as well. A nice elimination of a demarcation, but it says nothing of which side of the line you are standing. Are you on the steady state side (which, of course has never existed), or the transient state side (that is, the only one that has ever existed)? Be careful of your choice, as history (woops, there goes a transient) will mock you! ;-) Frequency, or spectrum, through the Supreme Force of the Universe's gift to us of "The Sinudoids" is intimately related to circular motion. Most intimate relations consist of back-and-forth. Acceleration we know is the rate of change of velocity. Faster - faster - FASTER! In the steady state at DC electric charges are moving at a constant velocity. You are confusing charge with carrier. Thus when moving in a straight line at constant velocity there should be no "waves" launched or radiated, no? Well, are you afore it? or against it? My point here is the assertion of the real existence of DC waves either guided or free! Edison would have beat Tesla to transferring power over the air if that were so. Problem is wavelength, you need infinitely long halfwave antennas - umm, WOW inspiration! That is exactly what Edison had. He DID beat Tesla with transferring DC power over the air when he supplied all his customers with antennas. AND they used guided wave principles. Q0: Is there electromagnetic radiation (are photons emitted) from a solenoidal (helix) carrying DC because of the centripital acceleration of the charges? Of course. Q1: Do electromagnetic "waves" exist at DC, whether guided or free? That has been historically shown. Q2: Can incident DC "waves", whether guided or free ever be "reflected"? Certainly. Q3: Can a VSWR be measured (at zero frequency) on a transmission line/waveguide that supports DC? Break the line and hold each half with your hands. Q4: Is the VSWR at DC related, in any way at all to the VSWR at higher frequencies? You just said it, frequency. Transient! For shame. Pete, just plain crazy, none of this is reality! You don't believe your eyes? There's a career for you heading the CIA (or Justice Department, or Homeland Scrutiny, or... choose one) under the current administration. most RRAA'ers seem Sorry about that insecurity thingy. Q4: If the Bird can't do it Should this be Q5 or at least Q4.1.v.1? Anyway, simply because you cannot afford that range slug doesn't mean the Bird cannot do it. Q5: If waves do not exist at DC, then at what magic frequency, lets call this frequency f(mgc), do waves cease to exist? Insecurity now is corrupting your confidence in the topic and polluting it with transients. As you dismissed them above, we (using the insecure form of I) might think you are suffering from optileptic seizures. Q6: Below what magic frequency, lets call it f(mgc), do radiation and or reflection phenomena stop? A Chebyshev filter might do it. Q7: What is the difference between a "conjugate match" and a "Zo-match" at DC? No conjugal relations? No back-and-forth. You can't tell the difference? Food for thought, eh? Slim Fast with half the calories. I miss dear old Reg! Thoughts comments... I can't think of a thing to say. 73's Richard Clark, KB7QHC Now that's more like it. Although I'm not sure how you make a Chebyshev with a cutoff right at DC. tom K0TAR |
