R: Emergency Communications



Hi Gopal, VU2GMN

>From a quick check of my log I see that we made QSO via AO40 on
20 august 2003 orbit 1288 and you was in Madras NK03DA

Also I have made many QSO via AO40 with Bob VU2MKP ,Vidi
VU2DVP, Raa VU2RM, Noel 4S7AVR, and Kumar VU2BGS

Since you are in the disaster area and you was involved in many
emergency situations I would like to know from you your opinion
about the possibility to properly use a satellite in HEO orbit like
AO40 (supposing it available) in order to communicate from your
QTH to the rest of the world to help for the emergency in this
particular moment in wich the propagation in HF is very bad.

I  hope that you and the rest of the above friends have not received
damages from the Tsumani

Tanks and 73" de
