m Key the transmitter with no microphone input, and ad-
just TC5003 for 0 V on the DC voltmeter.
HF/ 50 MHz Band Over-Current ALC Adjustment
m Connect the 50-W dummy load to the HF/50 MHz an-
tenna jack. Set the transceiver to 50.1000 MHz, and se-
lect the CW mode. Use Menu #22 to set the 50 MHz RF
power to maximum.
m Select "Alignment" menu item F-11 [HF IC ALC] and
adjust the main DIAL for a 1-segment ALC meter de-
flection.
VHF/UHF Band Over-Current ALC Adjustment
m Connect the 50-W dummy load to the VHF/UHF anten-
na jack. Set the transceiver to 145.0000 MHz, and select
CW mode. Use Menu #23 to set the 144 MHz RF power
to maximum.
m Select "Alignment" menu item F-12 [V/UHF IC ALC].
Key the transmitter, and adjust the main DIAL for a 1-
segment ALC meter deflection.
HF band Output Power Adjustment
m With the 50-W dummy load and inline wattmeter con-
nected to the HF/50 MHz antenna jack, set the trans-
ceiver to 1.8400 MHz (for the "Belgium" version) or
14.2000 MHz (other versions), and select the CW mode.
Use Menu #21 to preset the HF RF power to maximum.
m Select "Alignment" menu item F-15 [HF PO 100W]. Key
the transmitter, and adjust the main DIAL for 100 W
on the inline wattmeter.
m Select "Alignment" menu item F-14 [HF PO 50W]. Key
the transmitter, and adjust the main DIAL for 50 W on
the inline wattmeter.
m Select "Alignment" menu item F-13 [HF PO 10W]. Key
the transmitter, and adjust the main DIAL for 10 W on
the inline wattmeter.
50 MHz band Output Power Adjustment
m Leave the 50-W dummy load and inline wattmeter con-
nected to the HF/50 MHz antenna jack. Set the trans-
ceiver to the 53.5000 MHz, and select the CW mode. Use
Menu #22 to preset the 50 MHz RF power to maximum.
m Select "Alignment" menu item F-19 [50 PO 100W]. Key
the transmitter, and adjust the main DIAL for 100 W
on the inline wattmeter.
m Select "Alignment" menu item F-18 [50 PO 50W]. Key
the transmitter, and adjust the main DIAL for 50 W on
the inline wattmeter.
m Select "Alignment" menu F-17 [50 PO 10W]. Key the
transmitter, and adjust the main DIAL for 10 W on the
inline wattmeter.
144 MHz band Output Power Adjustment
m Connect the 50-W dummy load and inline wattmeter to
the VHF/UHF antenna jack. Set the transceiver to
145.5000 MHz, and select the CW mode. Use Menu #23
to preset the 144 MHz RF power to maximum.
m Select "Alignment" menu item F-22 [144 PO 50W]. Key
the transmitter, and adjust the main DIAL for 50 W on
the inline wattmeter.
430 MHz band Output Power Adjustment
m Leave the 50-W dummy load and inline wattmeter con-
nected to the VHF/UHF antenna jack. Set the transceiv-
er to the 435.0000 MHz (TYP B1, B2, C1, C2) or 440.0000
MHz (TYP A1, A2, H1, H2), and select the CW mode.
Use Menu #24 to preset the 430 MHz RF power to maxi-
mum.
m Select "Alignment" menu F-23 [430 PO 20W]. Key the
transmitter, and adjust the main DIAL for 20 W on the
inline wattmeter.
TX Gain Adjustment
m As you step through the procedures below, connect the
50-W dummy load and inline wattmeter to the HF/50
MHz or VHF/UHF antenna jack, as appropriate. Con-
nect the AF generator to the MIC jack.
m Use Menu #25 to set the MIC gain for maximum. Use
Menu items #21-24, as appropriate, for setting the RF
power to maximum on the band (below) being adjusted.
m Inject a 1.5 mV (1.8 ~ 28 MHz) or 2.0 mV (50 ~ 430 MHz)
audio signal at 1 kHz. Select the appropriate "Align-
ment" menu function in the chart below, and adjust
the main DIAL for the corresponding power. Remem-
ber to move the dummy load and inline wattmeter to the
VHF/UHF antenna jack for the last two steps.
