I learned from experience that my soundblaster card would put out second 
harmonics.  With a wide transmit passband, and a 1000 hz note, you might 
also be transmitting a 2000 hz note.  Therefore, I try to confine my 
transmitting to the top of the passband, or to use a narrower transmit 
filter.  Same reason as using "high" tones for RTTY --Brent N9HZ
