Roderick, 

Keep in mind that to perform direction finding one needs at least three independent receivers/antennas.  Therefore the Angelia board with only two coherent receivers will not be able to perform direction finding functions by itself.  The earlier-mentioned "daughterboard" approach for Angelia to add an additional ADC for a third receiver is likely not going to be a practical approach due to lack of header connections to be able to support such a board on the Angelia PCB.  At least that's my understanding of the situation.

 I know that Abhi is working on a design for a four-ADC receiver board for the Atlas bus that would do a great job for that application but it is still in the very early design stages presently I believe.  The board will almost certainly be a receive-only board but could be used with a Penelope/PennyLane transmitter, of course.
