I remember at least two times the LEO's were used for emergencies, on one
occasion, I actually transferred some health and welfare traffic. The one I
participated in was during the bad ice storms along the northeast coast
during the winter of (1998 ?). I personally forwarded health and welfare
traffic from two Canadian satellite stations who were in an area where there
was no electricity for over a month. As poor HF propagation and marginal
portable antennas weren't getting out the only way to communicate was via
the LEO FM birds. I remember passing information via AO-27 at least twice. I
also remember the difficulty of getting out the information that the
satellite was being used for an emergency :-) . The second occasion(as
noted, in another post) was during the Pacific Tsunami disaster (around
2004?) it was proposed that the store and forward digital PACSAT's were to
be used to pass health and welfare traffic out of some islands in the
Pacific Ocean that were devastated by the Tsunami. If one was to search the
AMSAT archives there were threads started both times.

Hi Trevor, M5AKA
I agree with you.
I remember that only the HEO satellites OSCAR-10,OSCAR-13 and AO40 were used
during the emergency when necessary.
My opinion is that we satellite operators we are not actually organized to
use the LEO Amateur Satellites during the emergencies so that we only
collect grids and QSL's with them as well we receive only telemetry.
I'm also not aware of any LEO amateur satellite having ever been used for
Emergency Communications but read please the following address of AMSAT and
you will surprised to read that even the LEO Amateur Satellites are built by
AMSAT to provide communications during emergencies and calamities.
VO-52 is India's contribution to the international community of Amateur
This satellite will play a valuable role in the national and international
scenario by providing a low cost readily accessible and reliable means of
communications during emergencies and calamities like floods , earthquakes

An interesting question. I'm not aware of any amateur satellite having ever
been used for Emergency Communications, do you know of any ?
Yes announcements were made that amateur satellites were available for
emergency communications in both the 2004 Indian Ocean Tsunami and the 2011
Japanese Tsunami but as far as I'm aware they were never actually used.
I think the problem is two fold:
1) The lack of satellite operators, only one to two thousand world-wide
2) The initial complexity of satellite operating e.g. Doppler, Tracking,
which means those without satellite experience cannot rapidly pick it up
when an emergency strikes.
A 100 watt HF station with a dipole on 40m is far easier to set up in an
emergency and will give you a range comparable with satellites and freedom
from the restriction of a 15 minute pass time.
