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 Radio Operators. 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 etc.

Hi Dominic,
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.

I am interested to know if someone in BB has used or is using the actual Amateur Satellites during the emergency occurred in Oklahoma and Texas because of the actual tornado's.
We know from TV that almost 50 peoples died and if the Amateur Satellites were used with success that will be a useful opportunity to demonstrate worldwide to the autorities that our satellites are useful and necessary during the emergency.
The call letters of the Amateurs partecipating as well the FM and linear Amateur Satellites used to help into the emergency will be appreciated.
Thanks for any info.
