RE: Amateur satellites and disasters...

While equipment costs for Mode A or Mode B groundstations are still at this 
time less than for Mode S the key issue is not which bands are used, it's 
more basic than that. The countries in the affected region need tens of 
thousands of trained and equipped Radio Amateurs on the ground. These 
countries have highly educated urban populations but at present the 
Governments actively discourage Amateur Radio which is why there are so few 
Amateurs out there.

It's not the lack of money in these countries that's the problem, a 
significant percentage of the population are now well off - just check the 
number of Cell Phone users out there!, it's Government attitudes that need 
changing and to be honest even if we had working Mode S or Mode B sat's 
without a large number of Amateur Operators out there to use them they would 
be of little use.

As this email from from Victor, 4S7VK, president or vice president of
the Radio Society of Sri Lanka shows they are short of HF radio equipment,
especially transceivers that run on a 12 volt supply. Many of their radios 
are the
older valve sets such as TS 830 requiring a mains
supply-there is no mains supply and portable generators are in short supply.

Malcom, can't get through to the number  I will keep trying.  Just exhasted
after a very hard day getting emmergency communications arrangements. All
forms of communications are down and only HF has a chance, so a teach of 5
is travelling through the night. We are setting up an oper centre in the
Prime Minister's offical residence.  I really hope our efforts will work.

We have an acute shortage of equipment for these field operations  eithout
electricty  For example we have a ham in one of the worst hit areas but he
has a TS 830 which he can not run off 13.5v. Anyway depending on how things
work tomorrow we might be in a position to get State support.. Mainthing is
we want to ease the human siffering and much could be done if they have a
two way link.
