Michelle,
I am kind of surprised that AMSAT-BB is the first time I have heard about a design review that could impact the AREx design for the Lunar Gateway SDR. As I stated in the AREx meetings, I want to ensure we have a host of independent space experts that are pre-selected and vetted for all our design reviews. This has not been done yet. And it will be an essential element for AREx to move forward on our Lunar Gateway payload with the space agencies.
This design review has not been communicated to the AREx team. We absolutely need to have open and full team communication on all design developments to ensure AREx mission success. Not communication to AMSAT-BB, where only a small segment of the AREx team is a part of.
As the acting Program Manager for the AREx Lunar Gateway initiative, I would appreciate you letting us know ahead of time of any planning for design reviews as well as any planned meetings that can affect the AREx system design. If I remember correctly, I was expecting a plan from each team on their efforts to evolve their systems over the next several months. This is a critical first step. We also need to get a handle on who all is on this team so that we can ensure that there is open, effective and impactful communication across the team and the subsystems.
I would appreciate your attention on this matter.
Thanks,

Which existing product most closely match the completed P4XT functionality?
Are there any affordable modulators for Ham Radio ground stations?

Greetings all!
A design review workshop has been scheduled for 7am Pacific 30 July 2020 for the 6U digital multiplexing transponder from Open Research Institute. This work is made available for free to the general public and assumes AMSAT as the primary audience and beneficiary.
The design is the same as one in progress for AREx (AMSAT/ARISS USA). The design review will be of direct benefit to AREx and meets their requirements.
The design is under consideration for other missions.
If you would like to participate in the design review workshop, then please write me at w5nyv@arrl.net for a Zoom invite.
The communications functions and circuits are the focus of this review.
