I am posting this on behalf of my friend, a chief pilot of an airline
working for JMC ( http://www.jmc.nu ) peacekeeping force in Sudan.
They operate a gamut of russian aircraft and require US-made VHF radios,
antennas and intercoms for them. Since Sudan is on the US Dept. of State
list of bad states, it's almost impossible for them to obtain avionics
from the US, even for international peacekeeping organizations.

No flames, I am just courious as to why they need "US-made" avionics
and accessories?
