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? :-)
