[hpsdr] ANAN200D RX1/RX2 Phase Coherent and Phase difference (2)

[Bryan Rambo]

Hi Warren,

Scott's comments notwithstanding, I am ashamed to admit I didn't even know
that the RX I/Q samples entering Callback3Port don't generally belong to the
same clock strobe.  So now, my little weekend project with VAC1 has turned
into the prospect of tampering with wdsp.  Gulp....

73, Bryan W4WMT

Hi Bryan,

As I understand, I think the intent is to have diversity ENABLED so that 
both DDCs run with the same phase word.  There are, of course, ways that 
Joe's idea of getting the two streams out (with diversity enabled) could 
be done.  They would, however, require some architectural change in the 
software.
