SETTINGS CONNECTION ADJUST ADJUST FOR
Remove TP7-TP9 Jumper PCB.
TX FREQUENCY:
Set mode to LSB Connect Frequency Counter to TP3 (top bare lead of R74). VR21 Key TX; Adjust for 16.2675MHz ±20 Hz.
CARRIER OSCILLATOR OFFSETS:
TX Mode
Freq. to 26.965MHz Band E
Connect Frequency Counter to TP6 (top bare lead of R102).
L28
LSB/TX mode: Adjust for 10.6975MHz ±20Hz.
Connect Frequency Counter to TP6 (top bare lead of R102). L27 USB/TX mode: Adjust for 10.6925MHz ±20 Hz.
Connect Frequency Counter to (top bare lead of R151). L26 AM/TX mode: Adjust for 10.6950MHz ±20 Hz.
DRIVER BIAS:
Band Switch & Ch. Selector to 26.965 MHz Ch.1 Band E
Mode to USB
MIKE GAIN at minimum.
Remove metering jumper
Connect DC Ammeter between TP9 and TP8.
VR11 Key TX adjust for 50-75mA.
FINAL BIAS:
Band Switch & Ch. Selector to 26.965 MHz Ch.1 Band E
Mode to USB
MIKE GAIN at minimum. Connect DC Ammeter between TP9 and TP7.
VR10
VR20
Key TX & adjust VR10 & VR20 for minimum ( 0mA ) current. Next adjust VR10 for 50mA, then adjust VR20 for 100mA total.
Replace TP7-TP9 Jumper PCB.
RF AMP CHAIN:
Replace PCB shorting jumper.
Set mode to AM.
Set RF power switch to HI . Connect wattmeter to ANT output. L43, L44,
L42, L40,
L33 Key TX & adjust (in order) for maximum RF output . Recheck power at lowest & highest channels; readjust if necessary for balance across entire bandwidth.
SSB CARRIER BALANCE:
Set mode to USB
MIKE GAIN to minimum. Connect wattmeter to ANT output. VR7
Key TX; adjust for mim. carrier leakthrough on scope or wattmeter. Recheck on LSB mode. If necessary readjust for best balance of sideband suppression between LSB & USB
SSB ALC:
Mode to USB.
MIKE GAIN to maximum.
Inject two-tone audio signal of 500 Hz and 2400 Hz, 30 mV (-18 dBm) at MIC jack. Connect wattmeter to ANT output.
audio generator to Mic Jack VR12 Key TX; adjust for 25 watts PEP.
AM CARRIER POWER HIGH:
Set mode to AM,
MIKE GAIN at minimum.
RF Power to HI. Connect wattmeter to ANT output. VR13
Key TX; adjust for for 8-10 watts
CAUTION! Do not exceed this level. Damage to power transistors and inability to achieve 100% modulation from insufficient audio power will result.
AM CARRIER POWER LOW:
RF Power to LO . Connect wattmeter to ANT output. VR16 Key TX & adjust for 1-3 Watt output
RF METER:
Set mode to AM,
MIKE GAIN at minimum. Connect wattmeter to ANT output. VR8 Adjust so panel meter agrees with Wattmeter.
AMC:
Mode to AM.
MIKE GAIN to maximum.
Inject audio signal of 1KHz 30mV (-18 dBm) at MIC jack.
Connect modulation meter to ANT output. VR14 Adjust for 100% modulation depth.
FM DEVIATION:
Mode to FM
MIKE GAIN to maximum.
Inject 1 KHz, 30 mV audio signal at mike jack. Connect deviation meter to ANT output. VR5 Adjust for total deviation of 4.5 KHz.
The internet is a wonderful thing. Found this as the proper way to align a DX99V. Hope this suits your radio.
