Re: [EVGRAY] Re: RF power factor?

Body

Hector,

I was thinking of a MIMO phase synchronized burst so packets conform to
the modulation rather than the other way around.  This way one could use
the hyperbolic accelerated circular polarization and retain some
spectral density at a high Q factor narrowband.  Futureshit as the
transcoding and modulation would require some serious calculations
realtime. Yeah an LP would work great for this, perhaps an othagonal pair.

Hey did you setup a diskcone antenna for your emergency comm or yagi or
LP with a rotator?

It's hard for me to grasp the parabolic transmitter antenna on voyager
doesn't  spread enough to loose all signal by the time it gets this far,
what is the tightest RF beamformer you know of?
