In my recollection there has been no option to anything with a command
receiver at all in past satellites. This receiver was ON to be able to do
its function regardless of other 'activities' on the satellite. In other

absolutely essential for the health (and recovery) of the satellite and its

Please don't assume that it's ok to have the power to a command receiver
switchable without substantial discussion and review.  All prior AMSAT
projects that I'm aware of have had command receivers always on, even if
they weren't always in use.  I'm pretty confident that includes both of a
redundant pair.  Happy to be corrected by others with better knowledge of
history if I'm mis-remembering some relevant case.
