Spooky 2.
As a fairly old Freight Dog I am also always willing to learn from others.
You have time over me.
I have 40 years in aviation but only 20 as Flight Crew, and a lowly F/E at that.
However I was told many years ago that HF off for Take Off was good practice for the very reason in post no. 1.
Obviously if you can inhibit Selcal for T.O. then that is good enough, but our old A300s dont have this option. (selecting off freq would be another option)
Fly safe and Happy New Year.
