It has always been the responsibility of a station to check to see if the
frequency is in use before transmitting and ID at least every 10 minutes.
There are current examples where they don't however, and they should. As an
example, some digital modes that are not compatible with modes often transmit
over stations that
are on frequency since the operators are only watching their computer monitors
and not listening.
Perhaps we should ask the ARRL for guidance and get a definitive answer.

Hi guys,
as I understand it, NASA wants as many hams as possible to send out
series of half minute long carriers, for several hours, on many specific
frequencies decided by NASA and covering all the most used segment of 10
meters!
To me that looks like incitation to create massive QRM!
Yes, NASA asks participants to comply with the laws. That would mean
listening first, not using a frequency if it is in use, and asking if it
is in use, plus IDing basically after each of the "dits" of that HI
message. But will all participants do that, or will they just put their
carriers atop other stations? I fear that some fellow hams, in the fever
of the action, and finding "their assigned frequency" in use by some
stations they only hear weakly, might choose to simply ignore them!
Let's hope that this will not happen.
Manfred
