Leaving out the word "some" was a typo. -- 73, Cecil http://www.w5dxp.com Interesting Cecil, my vertical antenna is constucted from a 42 foot length of coaxial cable using the outer braid as the radiator (but the inner and outer are shorted together anyway) and this fat vertical "wire" is suspended inside a telescopic fibre glass pole from Spiderbeam ( not the conductive type). So, I guess my verical wire is quite well insulated and certainly not in contact with charged rain. We've had particularly heavy rainstorms lately in France and this is definitely rain or rain induced static., starting and stopping in sympathy with the rain storms very easy to identify. 73, Deni F5VJC |

Is anything about your antenna in contact with charged rain? Your noise problem might have the same cause as lightning, i.e. the global atmospheric electrical circuit. You might be experiencing simple corona discharge. -- 73, Cecil http://www.w5dxp.com |

Cecil, can you state that if an antenna is in the house one would not
hear static? I seem to remember that when I was at the top of a mountain in a rain forest I put the antenna inside the car but the noise was S9 plus.... no communication could get thru Bearing this in mind static noise was radiated to the antenna was it not? So why cannot a droplet falling at 32 ft per sec sq not produce radiation or if it impacts a dielectric transfer a electric charge with curl? Isnt this lightning on a small scale? What I am getting at I suppose is if the antenna is protected from the environment and gets static noise surely it is a radiaated phenomina. IR antennas have never stated that their antenna was immune to static!

I can state that if an antenna is in a closed house one would not hear *precipitation static* which by definition, involves charged particles. Here's the definition. http://www.atis.org/tg2k/_precipitation_static.html But there are lots of other kinds of static. I just heard on The Discovery Channel that a certain percentage of the static we hear is left over from the Big Bang that happened some 12.5 billion years ago. There's lots of static here in East Texas, mostly from lightning and old power line equipment. I have never noticed precipitation static in TX or in CA. But it was overwhelming in the Arizona desert. -- 73, Cecil http://www.w5dxp.com |

Cept the Big Bang wasn't...
Looking back in time by looking out into the universe is only partially correct (yes those photons may have traveled 12 billion light years to get here, that does not make them the beginning of the universe, it only makes them as far as we can see at this point in our technology .... There is a force pushing mega amounts of matter (clusters of galaxies) apart in spite of the local gravitational well that by BBT has to be pulling them back together - a force that was absolutely NOT predicted by the BBT nor can be accomodated by it without adding some constants here, removing some there, changing the value of this and tweaking that - and those frantic tweaks again and again are not as a result of calm, cool, theoretical considerations, but because the *^&$#)@! universe is not cooperating!... As a scientific explanation the BBT resembles The House that Topsy Built, only more rickety... And then there is the little complication that there is NOW energy contained in every cubic inch of empty space, and E = MC^2, and -oops- the total weight of the universe has changed 'again', the Hubble constant rolls off into the weeds 'again' ...

No one can live in that "House" because it is rickety. So live in the street instead? Fine if your neighborhood is the Garden of Eden, but it rains here, and this old house, as rickety as it is - still has a tight roof. 73's Richard Clark, KB7QHC |

Ah, another foray into cosmology - and here in a rain static thread! The BBT is indeed venturing further and further into the land of "just so", and reasonable thinking people and not just RWC fundies (who do not think) can legitimately find some problems with it. I still await proton decay. But I have a gut feeling we may not find it........ - 73 de Mike KB3EIA - |

Creationist? Me? Surely you jest, Shirley... I am not superstitious...
Well, a little knowledge is a dangerous thing, they say... And in a lifetime of accumulating a little knowledge I have noticed a few things along the way... FIrst mathematics is simply a language, just another way of describing things... And when I was a majors candidate in science I noticed when taking math that equations can describe things that cannot exist in the physical world... I remember one physics course where the instructor, droll fellow by the way, 'proved' that the universe is multidimensional (Fime, Superstring, etc.)... His equations balanced on both sides and therefore it had to be true, so he said... At the same time I was also a majors candidate in the Arts and I had noticed this priceless contribution to another world of language: `Twas brillig, and the slithy toves Did gyre and gimble in the wabe: All mimsy were the borogoves, And the mome raths outgrabe.. . . ', etc... Now I gotta tell ya, as a farm boy from the thumb of Michigan I have pitched my share of manure and know it when I smell it... Lastly, we have to be careful of falling into the trap similar to a former Director of the Patent Office who declared everything important had already been invented... It is easy to simply fall in line with the big names and big reputations declaring that the BBT explains everything and that settles that... There is science and technology yet to come that will find distance, forces and energy in the universe that is likely to turn the BBT onto its ear... So, for the moment I remain a thoughtful agnostic RE the BBT... denny |
