3. Close the key and note the carrier
level on the analyzer. Then change
to the USB mode.
4, Press the MOX button and adjust
VR4003 for minimum carrier level
(less than 40dB below the CW
carrier level noted in step 3).
5. Change to LSB mode and confirm
at least 40dB carrier suppression
while transmitting.

2. In FM mode, tune the transceiver
to the center of the 144 MHz
band. Set the MIC Gain fully
counterclockwise and DRIVE fully
clockwise.
3. Press the MOX button and adjust
VR6001 so that the spurii at 13.79
MHz on either side of the carrier
are at least 65dB down.
4. Press the MOX button again to
return to receive.

3. Press the MOX button and adjust
the trimmer inside the TCXO
(X4002) housing for 145.00000 MHz

430 MHz TX RF (on 430 MHz RF
Unit - requires tracking generator
and spectrum analyzer)
1. Connect the tracking generator to
J7009 on the 430 MHz Main Unit,
and couple the spectrum analyzer
to the 430 MHz antenna jack.
2. Set the tracking generator output
to -30dBm and adjust CV7003,
Cv7004, TC7002 and TC7003 for
the passband shown (reducing
injection level, if necessary, to
avoid saturation).

430 MHz TX IF, Part I (on 430 MHz
RF Unit - requires dummy load and
wattmeter)
1. With the dummy load and wattmeter
connected to the 430 MHz antenna
jack, tune the transceiver to the
center of the 70cm band, FM
mode.
2. Press the MOX button and set the
DRIVE control for 4W output.
3. Adjust T7006-T7010 for maximum
deflection on the wattmeter (but
do not exceed 5W output: reduce
the DRIVE control setting, if
necessary).
4. Press the MOX button again to
return to receive.
