PO Meter Calibration
r
With the wattmeter and 50
W
dummy load connected to the
antenna jack, select the CW mode and set the meter to read
power output.
r
Key the transmitter, and adjust the
RF PWR
control for 100
watts on the external wattmeter. Then adjust
VR3014
so the
transceiver’s PO meter also indicates 100 watts.
Reverse ALC
r
Connect the 16.6
W
dummy load (or three 50
W
loads in paral-
lel) to the antenna jack, preset the
RF PWR
control fully-clock-
wise, and select the
CW
mode. Key the transmitter, and adjust
VR3002
for 50 watts on the transceiver’s PO meter.
SWR Meter Calibration
r
Connect the 16.6
W
dummy load (or three 50
W
loads in paral-
lel) to the antenna jack, then preset the RF PWR control fully
clockwise. Select the
CW
mode, and set the meter to read SWR.
r
Key the transmitter, and adjust
VR3015
so the meter indicates
3.0:1 SWR (within 1 bargraph segment).
IC Meter Calibration Check
r
With the wattmeter and 50
W
dummy load connected to the
antenna jack, select the
CW
mode, and set the meter to read
IC. Preset the
RF PWR
control fully clockwise.
r
Key the transmitter, and confirm 12A ~ 21A IC meter indica-
tion.
SSB Modulator Balance
r
With the 50 dB attenuator and spectrum analyzer (or 50
W
dummy load and sampling coupler) connected to the antenna
jack, and the
MIC
gain control preset fully counterclockwise,
select either SSB mode. Alternatively, a separate receiver can
be used, with the transceiver connected to the dummy load.
r
Set the menu function 8-9 to “ -200 .”
r
Key the transmitter, and adjust
VR3012
for minimum power
output (carrier leakage, which should be lower than -50 dB) as
indicated on the spectrum analyzer or external receiver.
AM Carrier Level
r
With the wattmeter and 50
W
dummy load connected to the
antenna jack, select the AM mode, and set the meter to read
ALC. With no microphone input, preset the
RF PWR
control
to the fully clockwise position. Key the transmitter, and adjust
VR3011
for ALC meter deflection to the top edge of the ALC
zone.
COMP Meter Calibration
r
Set the PROC and RF PWR controls fully clockwise, and
press the PROC button to activate the speech processor.
r
Set the meter to read COMP, and preset the MIC gain control
to the 1-o’clock position. Inject a 1 kHz tone at 2 mV level to
the mic jack, and adjust
VR2007 so that the transceiver’s
COMP meter deflects to the 10 dB mark on the COMP scale.
FM Carrier Frequency
r
With the 50 dB attenuator and frequency counter (or 50
W
dummy load and sampling coupler) connected to the antenna
jack, preset the
FM mic gain control fully counter-clockwise,
select the
FM
mode, and tune to 29.0000 MHz. Key the trans-
mitter, and adjust
L2026
for 29.0000 MHz (±50 Hz) on the
frequency counter.
FM & CTCSS Tone Deviation
r
With the 50 dB attenuator and linear detector (or 50
W
dummy
load and sampling coupler) connected to the antenna jack, se-
lect the
FM
mode, and tune to 29.2000 MHz.
r
Set the
FM
mic gain control fully clockwise, and inject a 1 kHz
tone at 10 mV level to the mic jack. Key the transmitter, and
adjust
VR2009 for ±2.3 kHz (±0.1 kHz) on the linear detector.
r
Select the 88.5 Hz (default) subaudible tone, and press the RPT
button to activate CTCSS operation. Key the transmitter and
with no microphone input, and adjust
VR2008
for 0.5 kHz
±0.1 kHz on the liner detector.
FM Mic Gain
r
With the 50 dB attenuator and linear detector (or 50
Ω
dummy
load and sampling coupler) connected to the antenna jack, tune
to 29.200 MHz, and select FM mode.
r
Inject a 1.8 mV signal at 1 kHz to the
MIC
jack. Key the trans-
mitter, and adjust
VR6807
for 1.75 kHz ±0.1 kHz on the lin-
ear detector.
Transmitter Carrier Point
r
Turn the transmitter off, then press and hold in the
FAST
and
LOCK
buttons (near main VFO knob), then turn the transceiver
on.
r
Recall menu function 9-0 and select “ t-LsbcAr ” using the
SUB VFO-B dial.
r
Select the
LSB
mode and then inject a 1 kHz tone to the mic
jack. Adjust the injection level to the point where the ALC meter
no longer deflects.
r
Adjust the injection frequency (within 800 ~ 2000 Hz) for peak
RF output, then adjust the injection level for 80 W RF output.
r
Set the injection frequency to 350 Hz, and adjust the MAIN
VFO-A knob for 20 W RF output.
r
Select “ t-uSbcAr ” using the SUB VFO-B knob, and select the
USB mode. Inject a 1-kHz tone to the mic jack, and adjust the
injection level to the point where the ALC meter no longer
deflects.
r
Adjust the injection frequency (from 800 ~ 2000 Hz) for peak
RF output, then adjust the injection level for 80 W RF output.
r
Set the injection frequency to 350 Hz, and adjust the MAIN
VFO-A knob for 20 W RF output.
