TS440S.6

TS-440S DISPLAY CALIBRATION
I found there was some shift in the reference oscillator
frequency of my TS-440S.  This can be noticed and corrected
as follows:
1.  Remove the top and bottom covers from the radio.
2.  Do not disconnect the speaker cable.
3.  Connect the supplied calibration cable between RF Unit
    and PLL unit, as shown in "Kenwood TS-440S Instruction
    Manual" on Page 24 in Section 5-8-3.
4.  Set VFO A to 10.001.00 MHz LSB and VFO B to 9.999.00 MHz
    USB.
5.  Pushing the A/B function button, you can have different
    audio signals, if that 36 MHz reference oscillator is
    misadjusted.
6.  Using a small flat bladed scredriver, adjust trimmer
    capacitor TC1, near connector 8 of the PLL Unit (the
    location shown in Instruction Manual in the same section
    as above) until those audio frequencies from VFO's A and
    B are equal.
7.  Disconnect the calibration cable and reassemble the
    radio.  This procedure can be done by ear with good
    accuracy without any measuring equipment.  WWV is too
    weak here in Finland to use it as comparative signal for
    the procedured described in "Instruction Manual", Section
    5-8-3.
