I am looking for the top three strongest signals generated by both Nature and Man that can be read anywhere above ground in the world. 100% coverage is not required - but as close as is possible.
OR, perhaps the strongest signals across the largest continents.
And what are the top three strongest signals generated by both Nature and Man that can penetrate water and the ground. But in this case I would need to know where the signal sources are.
Hi Monyer Al-Fatlawi,
Thank you for your prompt answer, but I am looking for the strongest electrical signals - not power sources.
For instance, the Soviet Duga radar, capable of generating a 10MW radar signal, whose random frequency hops disrupted legitimate broadcasts, amateur radio operations, oceanic commercial aviation communications, utility transmissions, - resulting in thousands of complaints by many countries worldwide. It has long since been retired, however, and thus no longer qualifies today.
