Hi Dom,

You are right, of course, that for full xpol reception one 
would need two of the SDR-IQ, SDR-14, SDR-1000, etc., 
receivers.


SDR-IQ x 2 might be a cost-effective way to go, but as you 
say it will require a common LO feeding two boards. 
Moreover, I think something further would need to be done to 
synchronize the sampling phase on the two boards. 
Retro-fitting this to the existing boards may not be easy.


For now, I am thinking of the SDR-IQ --> Linrad --> MAP65 
combination as an attractive solution only for stations with 
single-polarization antennas.

Hello ,

in case SDR-IQ gets possivle to use with MAP65 , we also need to use 2 
boards with a common LO. It is possible to use an external LO on SDR-IQ 
, but a better way would be to one board LO to drive the other board , I 
don't know wether it is easily possible  to do this , I don't have board 
schematics .
