How can FSK using the Omni VI FSK keying input be made to splatter? 
Could you do that by putting too high a baud rate in there? Or could in 
between proper Mark and Space logic levels make noise from switching 
diodes or transistors not fully on or off? The FSK input on the Omni VI 
switches between two padding capacitors in the BFO. Only one BFO 
frequency can be generated at a time in either Mark or Space mode. There 
are not two tones to create IMD, just one tone at a time. Even if you 
over drive a PA, one tone is one tone. How can you mess this up?
