I'll admit to knowing nothing about the technicalities or regulations re: reading out/reading back "next frequency", but I have noticed at LPL controllers have gone from saying:
"...contact Manchester on 128 decimal 35"
to
"...contact Manchester on 128 decimal 350"
This additional zero is now also added to "119.85" now "119.850" and "126.350"
Any reason for this? New regulation?
