The KX1 offers 4 sidetone levels, 3 if you discount "off", generated
from two pins of the PIC16 microcontroller, which are toggled high and
low through two resistors to the audio amplifier, forming a primitive
resistor/amplifier DAC.
Additionally, the KX1 (unlike the K2) mutes the RX during STL and STP
menu operations, making CW beating harder.
A recent article in Electronics World magazine (11/2004, p.47)
discloses a technique to obtain ternary values from the MPU's I/O
pins. The technique uses the three 0/1/HiZ states to provide 3 output
voltage levels per pin, instead of just two....
