CLEAN and NOT Interfering is the part 97 rules,
Nothing is spoken of about bandwidth, just stay inside the bands .
FIX EM, YES, make it a good clean signal, don't change them !
Otherwise, I sugest we all move back to CW only, that has a much smaller
bandwidth.

what's the SNR with the 10 Khz signal? Or is that a reasonable question?
