Amos,

as discussed previously MAP65 when used for polarization diversity
requires a pair of synchronized I/Q channels which must be interleaved,
that is not possible if your starting point is two separate stereo
channels containing I/Q data. Either a 4 channel audio device feeding an
interleaved pair of I/Q channels, or Linrad is supported using an
interleaved pair of I/Q channels via UDP in Linrad's own message format.
