Older Beacons must be Replaced
Starting on Feb. 1, 2009, NOAA satellites will only receive signals from the new 406 MHz frequency beacons. The older emergency beacons, operating on the 121.5 and 243 MHz frequencies, will no longer be detected by SARSAT. Signals from the 406 MHz beacons can be detected instantly, are more accurate, and offer global coverage. NOAA has provided advance notice of the switch since 2000.
“It’s vital that anyone with the old 121.5 MHz beacon make the switch to 406 MHz beacons immediately so their distress signals can be heard,” said Chris O’Connors, program manager for NOAA SARSAT. “Plans for this changeover started in 2000 and we want everyone that relies on these devices to have the proper equipment.”
