A few quick comments.
1. May need a down converter shown between the 5.6/3.4 GHz receive
LNA/LNB and the A/D due to the frequencies and bandwidth involved.
2. Local power options for the remote would allow for non-metallic
Ethernet connections, facilitating far remote operation.
3. Likewise, generalizing the user interface/PC to a generic Ethernet
non-metallic interconnection would allow for remote "indoor unit" operation.
4. Multiple "outdoor units" on one "indoor unit" or one "outdoor unit"
controlled by multiple "indoor units" should be feasible and perhaps the
designs could generally address this sort of deployment.
5. The bit rate between the LNA/LNB and the user interface should
probably be checked for the various possible configurations.
6. Multiple outdoor units with common control should allow for
diversity or multiple azimuth applications.
7. Diversity applications suggest receive only or transmit only units
might be desirable.

It's on the web and in the feed. Authored by KB5MU et al, this is the
current conceptual block diagram of a MEP station. As always, comment,
critique, and feedback are welcomed and encouraged.
