But the way that the rules were explained was that you could only or had to
to be legal generate the signal using the USB channel of a SSB or ISB
transmitter. If the FSK signal is generated by feeding AFSK into an SSB
transmitter, and receive it with an USB receiver, you will get the same results if
you feed the normal AFSK into the USB transmitter or feed the inverted AFSK
into the LSB channel. And absent residual carrier to give it away, no one
would be the wiser. The same is true of CW whether generated the old way or
the new way.
Obviously you would in the "illegal" cases have to put the suppressed
carrier in the wrong place.
