The 4th number gets missed out quite a lot.
instead of 119.125 I get 119.25 read back. I think pilots are subconsciously listening for the first 3 digits, then only 2 after the decimal, so the 4th number gets missed.
Bloody nuisance. I wonder how many incidents or near incidents have been caused by crews going to an empty frequency when the controller who was expecting them really needed them to be on his frequency?
