Thanks John, when this happened, it was myself, my instructor and another guy. At our club it seems if you ask 5 people their opinion you will get 5 completely different opinion, my instructor is also my friend and has been flying for 25 + years I think I will stick to what he says, so we sent the radio back to JR as it is still under warrantee. Thanks for all the help, I will keep you informed as to the outcome
