Ho Rob:
If you are getting a square wave out of your sidetone, then you probably
have a problem someplace. I just put the sidetone from 5413 on the scope
and is shows an almost perfect sine wave.

I find the square wave character of the stock sidetone quite annoying on
my K2 #5004, with the sidetone set at 500 Hz. However I run the audio
through a SCAF-1 external audio filter, which makes the sidetone much
more
of a single tone, and far more pleasant to my ear. The SCAF-1 also
eliminates the high-frequency hiss in my headphones. The hiss didn't
seem
like a big deal, until I could make it go away; then I realized how much
it had been bugging me.
More information on the SCAF-1 is available here:

I have a K2, serial #2289, that has a second harmonic in the
sidetone. The
sidetone is set for 400 Hz because I do much better with lower
pitches. The
sidetone at 400 Hz has a definite square wave sound to it. The problem
certainly is not present at 600 Hz, and I don't even want to try 500
Hz. I'd
go lower than 400 Hz if the K2 allowed it.
