The downlinks in Lyle's SDX block diagram are two-fold. S and V. The only change I would make for Eagle is to make both of them HELAPS. This might prevent both of them being used simultaneously as HELAPS but it might not. We might choose to do a "delay only" version of the HELAPS for the second transmitter.
I would like to suggest that we use Mirek's command receiver to feed the exact same command receive technology to be used for P3E and that is the SDR/FIQ channel on the IHU-3. The less work we have to repeat, the better. I believe we should have stand alone command receivers independent of the transponder antennas. I would like to hear from John and Mirek on this. Mirek's command receiver is nicely done.

Short version: The matrix function is subsumed into the SDX modules.
To shed a bit more light, the SDX is designed with its own "matrix." There are two uplinks: U and L. The SDX can select either or both. It can send its output to V or S (or whatever the second downlink is now going to be) - or both.
At least, this is what we thought a year ago, and what we wrote up in the wiring harness report after the Colorado meeting last October.
