G'day,
Looks like 121.5 and 243 Beacons are on the way out!

The page states that only 1 in 50 121.5 Alerts are genuine cases of distress. Personally having flown a search on spurious 121.5 hits in the middle of nowhere for hours on end to no avail, the move to 406 only is great.
As far as what Guard means the US pubs specfically refer to it as 121.5 and 243. Wouldn't surprise me if some sets allow you to change the preset though as mentioned by someone else.

For those of us that fly with radios with a built in secondary Guard receiver we fly with TR + G (Transmit Receive & Guard) always selected to listen out for distress calls (Yes it does happen!) . Besides there's nothing like hurtling down the runway and listening to someone crap on on guard about useless s..t.
No really, it's ok!
Bugger, I promised myself never to get dragged into one of these useless obvious threads..
Regards,
PLE..
