You're right it is the power radiated during the day (1 MW at night), even if the efficiency at this power is very good, it is necessary to at least count 1/3 moreChristophe wrote:Ah yes you're right, according to the wiki page it is these orders of magnitude !!
He spoke good emitter of 2000 kW ... but we're talking about? The power input or output?
Radio amateurs provide this type of service.chatelot wrote:stay without a fixed or mobile phone for long enough
So a big radio transmitter is still useful!
The technique also makes it possible to send time signals with much less HF power (2 X less without AM modulation). The carrier could be activated to send these signals 1 time / hour and retain the possibility of transmitting at full power in the event of a disaster.
RNT should be able to provide this service, but is slow to set up due to lack of agreements.

Must also see that the reception in GO AM is more and more disturbed by the PLC, the parasites of everything that makes sparks, poorly shielded switching power supplies of our lamps, chargers ...
