FTDX10 Technical Supplement
ALIGNMENT -10
PA Unit Adjustment
Preparation
Connect the 50-Ohm Dummy Load and Watt
-
meter to the ANT jack.
Disconnect the coaxial cables from J4001 on the
FINAL Unit, then terminate J4001 with a 50-
Ohm resistor.
Disconnect the jumper plugs from J4004 and
J4005 on the FINAL Unit.
Pre-Drive Stage Idling Current Adjustment
Connect the DC ammeter to J4004 on the
FINAL Unit.
Rotate the [FUNC] knob to select the alignment
parameter “3-001 MF PREDR BIAS”.
Press and hold the PTT button then adjust the
[MPVD] ring so that the DC ammeter reading
is “100 mA (±10 mA)”.
Release the PTT button.
Rotate the [FUNC] knob to select the alignment
parameter “3-004 HF PREDR BIAS”.
Press and hold the PTT button then adjust the
[MPVD] ring so that the DC ammeter reading
is “100 mA (±10 mA)”.
Release the PTT button.
Rotate the [FUNC] knob to select the alignment
parameter “3-007 VHF PREDR BIAS”.
Press and hold the PTT button then adjust the
[MPVD] ring so that the DC ammeter reading
is “100 mA (±10 mA)”.
Release the PTT button.
Drive Stage Idling Current Adjustment
Connect the DC ammeter to J4005 on the
FINAL Unit.
Rotate the [FUNC] knob to select the alignment
parameter “3-002 MF DRIVE BIAS”.
Press and hold the PTT button then adjust the
[MPVD] ring so that the DC ammeter reading
is “500 mA (±50 mA)”.
Release the PTT button.
Rotate the [FUNC] knob to select the alignment
parameter “3-005 HF DRIVE BIAS”.
Press and hold the PTT button then adjust the
[MPVD] ring so that the DC ammeter reading
is “500 mA (±50 mA)”.
Release the PTT button.
Rotate the [FUNC] knob to select the alignment
parameter “3-008 VHF DRIVE BIAS”.
Press and hold the PTT button then adjust the
[MPVD] ring so that the DC ammeter reading
is “500 mA (±50 mA)”.
Release the PTT button.
