You do not understand what hapens when you send audio tones for rtty into a ssb transmitter. The end result of what comes out of the transmitter can not be distinguished from a true FSK transmitter. That means in effect the transmitter is not putting out AFSK but just FSK. On todays modern transceivers many of them use an audio tone in the USB mode to generate CW. In effect you are really transmitting FSK and not AFSK. If you switch the rig (as many multimode rigs can) to AM or FM then you are transmitting AFSK. This makes it not legal in the data frequencies of the low bands. ____________________________________________________________________________________ It's here! Your new message!
