Some ELT references

"The International Cospas-Sarsat System will cease satellite processing of
121.5/243 MHz beacons from 1 February 2009."

I did not find a reference to whether there is any FAA mandate that all
ELTs be replaced/upgraded, but they strongly recommend it in the AIM.

For those who want to know more about how your ELT signal gets detected
and the SAR process begins, check out the following links
