But a pack of | angry hams sending dots was worse than the woodpecker. But | anyway, after moving off the ham bands for a while, the | woodpecker came back with a chirped signal. That was | essentially unjammable. | | Over-the-horizon HF radar needs to closely follow the MUF, | staying just under it. So the woodpecker would drift up and | down through the ham bands as the day want on. | femto wrote: | I was working on the Jindalee OTHR at the time. We used to | sit in the control room listening in on the Woodpecker. We | also had quite a bit more power then the HAMs (beamformed) so | they didn't ignore us. | | (Jindalee also stayed clear of the HAM bands. The radar had | frequency exclusion tables built into it and there was a | switch which allowed the tables to be overridden if | necessary.

But a | fun conspiracy theory floated by my guide was that this | installation was intended as a Soviet weather control experiment. | The evidence for that, such as it can be considered, was that | allegedly there were supposed to be 12 reactors at Chernobyl, not | just the famously exploded Reactor 4, which would have been an | immense amount of energy production capability for one single | location. Additionally, the nearby Pripyat was inhabited by the | brightest of the bright, most elite of the Soviet population in | an already highly secret portion of the Soviet Union.
