ARRL have issued a post about 432-438 MHz P-Band SAR allocation.
Oddly they say:
"ARRL Chief Technology Officer Brennan Price, N4QX, said SAR activity has not been found to be a significant problem to Amateur Radio activity on the 70 centimeter band."
But there have not been any SAR satellites operating in 432-438 MHz so given the complete absence of any transmissions it is not surprising that there have been no significant problems.
The first SAR satellite in this band is AIST-2D which was launched a few days ago on April 28, 2016.
In 2002 the ARRL reported the FCC's WRC-03 Advisory Committee and the National Telecommunications and Information Administration's Radiocommunications Conference Subcommittee determined that SAR transmissions could periodically impact amateur reception and even held "the potential for significant interference."
