NIKNAK,
in response to your post, i agree that most glider pilots are usaully more postion concious than most powered pilot in open FIR but i think most are actually unsure if they are allowed to use and transmit radio messages without an FRTO license. As far as i know, gliders pilots may transmit on VHF without an FRTO. (Someone please confirm if i'm correct or not). I thinks another point raised is that most gliders lack comms equipment so for this reson, i purchased a handheld navcomm tranceiver so that im always equipped with a radio. I also use my volmet to listen to local ATIS transmision and Volmet ect. Thanks for you very sensible post anyway...
