Anyone know how long your transmission
has to be for the USCG Rescue
21 system to get an approximate fix by RDF?
I've heard the Coast Guard ask for assistance more than once in locating a vessel after they heard a brief message calling for help. I know it always took me a long time finding the null on a manual RDF moving the antenna
back and forth by hand for navigation
, just wondering how fast the new Rescue
21 system is presumably with computer controlled ADFs.
