Yawn, thanks for that. Nice reply.
I asked the original question as I work on the other side of the planet where it is a legal requirement for me to include the decimal point in all freq's.
In addition, we dont include Altimeter on the ATIS, we advertise QNH.
That's why I asked how Altimeter is broadcast on ATIS in the US because its a recent change where I work, that I now need to include on ATIS, as well as QNH.
