[Elecraft] KX-1 vs K1 Side-tone

[Don Wilhelm]

Kieth,

The KX1 sidetone is generated by an MCU output and is sent through an RC 
filter to smooth it, so the result is more sine wave-like than a square 
wave (but it is not perfect).
The K1 uses a DAC output for the sidetone, so it should be more like a 
real sinewave.
