Note the reference to a 400 newton propulsion system in this extract
from a bulletin of the American Radio Relay League (ARRL), an
organization for amateur radio operators.
Unfortunately, the ARRL persists in using ifp units in their articles
on building radios and antennas. Can you imagine how silly it seems to
measure out the elements for a 2 meter dipole in inches instead of just
using a metric tape? Perhaps this marks a new recognition of and move
towards using international units. A good start would be correcting the
text below to put the N in "newton" in lowercase, of course.

Ground controllers now are analyzing the telemetry sent via the S2
beacon on 2401.305 MHz. AMSAT-NA President Robin Haighton, VE3FRH,
says the command team worked through the holidays in an effort to
determine just what went wrong aboard AO-40. Among other things,
ground controllers would like to know what actually happened on
December 13 and why, as well as which telemetry functions are known
to be correct and which data are suspect and why. The satellite went
silent during maneuvers to test its onboard 400-Newton propulsion
system following an earlier orbit-shifting burn.
