Looks like a big Opera   set up

But for LF , may be not , the description talks of a wide band Rx , so there making a comb spectrum to feed the Rx over its b/w
as  for the  phasing  / frequency  match , I guess , there  using  distance 
, ie , some  one will  be at peak  at  any   time  during the  slot , so the 
qrg/phase is not  important  as  the  received energy will  be  'constant' ?

Hello group,

have a look at this:

http://www.jpl.nasa.gov/hijuno/

Now, can we use this technique to combine the efforts of many
transmitters to produce a collective, higher EIRP? Individually seen,
each transmitter does not break the law by sticking to the limit. If,
say, I have two equally configured transmitters on two slightly
different FFT bins, can I combine the two bins in order to get a
better S/N? Would that be a 3 dB improvement? What if I have more than
two (a whole continent?) worth of transmitters? :-)
