"If a dipole falls in a forest and there's no one there to hear it,
does it make a sound?" =============================== Yes. All falling trees make a sound. But if there's nobody to hear it who cares? But this business about 100 watt transmitters causing forest fires is exaggerated. Even if there's a conjugal impedance match between a dead leaf and the transmitter there's little to worry about even when its not raining. And the density of foliage is hardly likely to allow flames, should they occur, to leap from one leaf to another. The climate and type of tree involved is, of course, of some consequence. Deciduous trees and those found in South American and Indianesian jungles can be disregarded from this discussion, If you should live in Australia, the home of Eucaliptus trees, during the dry season, and it's always dry, there is a one in 100 million chance of a tree catching fire by radio. Always supposing by some remote chance it hasn't first been struck by lightning. Eucaliptus trees positively enjoy fire. They depend on it to propagate efficiently. This may be an unfortunate trait insofar as kangaroos and wallabies are concerned but alligators are quite happy with the way things have been arranged. The Aussies themselves take care not to build their houses too near to eucaliptus plantations. The Abbo's, with their 50,000 years of experience, radio or not, are quite happy and sensible enough to leave things as they are. The USA has wide variations in climate and tree population. Thoughtful citizens ought to concentrate their minds on hurricanes, twisters, atmospheric pollution and gun laws. 100-watt transmitters and G5RV's can look after themselves. ;o) --- Reg. |
