Some may think it is experimental but I personally find it very
disruptive to use certain digital modes on satellites.  It is more
disturbing when the stations performing these "experiments" fail to
minimize their station ERP to a reasonable level.

Tonight on FO-29 I witnessed first hand how disruptive it is when a
station decides to experiment with MSK144 while others are trying to
use the shared transponder resource.

Some of these modes are 100% duty cycle for periods, then switch off,
and back on again in a sequence.  This doesn't seem very compatible
with your typical satellite transponder.

For the life of me I cannot figure out why someone would even think
about attempting these modes on AO-7 when the transponder's more
sensitive nature is common knowledge.
