Turn
the CAL

to the 25K
position
and
use the
output
of the calibrator
circuit to adjust the coils. The
DRIVE
control
should
be set to the 12 o'clock
position
(the white line pointing towards the top of the transceiver).
The coils can be aligned from the bottom of the transceiver
without removing the boards.
Set the BAND
switch
to the correct band and tune the
VFO
to the frequency
shown
in Table
6 to receive the
calibrator signal. Use the test rod included in the accessory
bag to tune the appropriate antenna coils for a maximum

Adjust the coils for each
band
as described
in Table 6.
When you finish, turn the calibrator off.
CAUTION
The antenna
cores are fragile. Be careful not to
break them during alignment.
The
coils for each band should be adjusted
in the order
given above.
