TK-80 KAT-2 (Internal Automatic Antenna Tuner) 2. Auto tuning External View The transmitter power from the final unit passes through current/voltage detection transformers L1 and L2, which have toroidal cores. The current and voltage components detected here are rectified by a waveform rectification circuit consisting of D3 to D5, Q1, D6 to D8, and Q2, and are then phase-compared by IC1.
Page 107
The potentiometers used here are not ones that rotate through 360 degrees. Since the TK-80 limits the rotation angle of each potentiometer, the rotation range is from the minimum capacitance to the maximum capacitance, plus a little extra for headroom.
