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.
