Sorry something lost in my spot,

Hi guys

for diversity, beam steering, DF-application etc. you need independent
RF-channels only in the frontend. That's the reason why Joe is using up to
four synchronized mercuries.

Due to the necessary coherent sampling oscillator it's much easier to use
two 4-port ADCs ( 8 channels) in the frontend (problem nr. I/O ports of the
FPGA?)

I am also *very* interested in this, so if anyone starts a sub-group or
discussion please add me to it.

You are standing at the end of a road before a small brick building. Around
you is a forest.
A small stream flows out of the building and down a gully. The sunspot count
is 285.

"for me the next quantum step would be to having 7 hardware receivers
running coherently and allowing for phasing, thus making DF and beam
steering and nulling possible by software in receive ( and transmit ) mode.
No need for large beam yagis and rotators anymore. Joe has already written
a 3 Rx phasing sotware."
