Ok lets simplifies it

No need I've been sending and receiving RTTY for years so I know what
FSK and AFSK is and what it sounds like.
The question was..
Which frequency is the carrier frequency as regards HF and VHF
Beacons, and I suppose A/FSK data, in the Amateur service.
The Mark, the Space or in the middle for Amateur usage ( the frequency
you log in your logbook ).
Keying can be normal or inverted making the space either higher or
lower than the mark so saying that the mark is the carrier frequency..
occasionally.. is'nt much use is it ?.
