I think this idea needs to be carried through to a complete thought. What are you trying to achieve? If it is just to be the cool guy with a radio that gets propaganda from random countries, then stuff a radio in many layers of steel.
If you are looking for legitimate information in a time of crisis, I would put a satellite phone in the largest Faraday cage I could possibly build, and keep a few years of payment current through a reliable company on the other side of the earth... start making contacts and getting phone numbers now for people acrostic the world. Getting reliable info from random people that "heard" something is really just a wet dream if you really think it through, unless you are thinking local contacts, in which case there are no other radios to be heard anyways.
No force on earth has the ability to take out satellites in every hemisphere with one blast. The shear size of the blast would kill every human on earth. Now back to reason... there would still be plenty of satellites in orbit that were far enough away, or shielded by the earth itself. There very well may be a several hour period without service, but i would be ok with 16 hours of service.In the event of an EMP attack do you really think a satellite phone will be usefull with the satellites being the first thing to be taken out during an attack?
I don't think you quite understand the concept of emp - or 'electromagnetic pulse'.No force on earth has the ability to take out satellites in every hemisphere with one blast.

Here's a quickie: When a nuclear blast happens, one of the side effects - besides extreme heat, x-rays, gamma rays, and radioactive fallout - is a extremely large voltage pulse. This immense swarm of free electrons move towards ground in all directions relative to the horizon. It can affect electronics for thousands of miles from the actual blast - depending on the power of the device. The higher up the blast occurs; the wider the horizon. The net effect is fried transistors and diodes. So, satellites and computers and anything else in a given range will be toast. End of story.
