I have to write the info down, otherwise I forget too. Probably age related for me...!
And being left handed, I just wish the PTT button was on the right hand side of the yoke - a right pain having to swap hands to write down the info, then back to the PTT then back to change the squark/radio frequency. I'm guessing not such a problem if I flew a stick controlled plane! (or flew from the RHS!)
