5. There is no polarity to the filter.
Install the filter into its
position on the IF unit.
Solder the 2 mounting tabs,
and the 4 input and output pins to the circuit board
Solder sparingly, and heat the connections
only long
enough to insure a good solder joint.
Don't overheat
the filter or circuit board.
6. Carefully inspect
your soldering.
Be certain
that all
pins are
actually
soldered,
and
that
you
have
not
soldered across any spots on the board or between any
of the pins on the filter. Clip the pins fluse to the board.
7. Replace the IF unit in its place.
Make certain no wires
will be pinched underneath the board.
Replace the 7
screws.
8. Move the connection as illustrated when a CW filter is
installed.
9. Reinstall
the bottom
cover.
Reconnect
the speaker
lead, and reinstall the top cover.
0. Apply power and verify your work.
Filter installation is
now complete.
.3 TS-130SE
ANALOG
DIAL ADJUSTMENT
1. Turn the main dial fully CCW.
The red cursor should line
up with the VFO start mark on the sub-dial.
If it does
not, remove the main knob (2mm Allen), loosen the 12
mm
nut
and line
up the scale
start point to the red
cursor,
2. Turn the main knob to 50 kHz analog. Adjust the alumi-
num
slip sub-dial to line up with any one of the larger
black dial marks.
3. Note the digital error.
If it is MORE than 2 kHz adjust
the VFO trimmer cap TC1 (front under the seal tape) to
exactly 50.0 on the digital readout.
4. Turn the main knob to 450 analog.
If the digital error is
less than 2 kHz it is in spec.
If the digital error is
greater, proceed:
For instance if the digital error is 14.454.0 (plus 4 kHz),
multiply the error times 4 (16 kHz) and adjust the VFO
trimmer cap to the desired frequency (14.450.0) LESS
the error, or 14.434.0.
Next adjust the VFO inductor
L3 (center under the seal tape) back up to the desired
frequency of 14.450.0.
5. If the error in step 4 was in the minus direction, reverse
the direction of correction adjustment in step 4.
6. VFO
linearity
final check:
The
digital
readout
and
analog dial should agree to within +2 kHz at every 100
kHz dial point.
5.4 HOW THE TX FINAL TRANSISTORS ARE
Fi
re}
PROTECTED
nal
transistor
protection
is provided
by sampling
the
flected power.
As the reflected power is increased (higher
SWR) transmitter drive is reduced, thus decreasing input to
the final transistors.
This in turn reduces
collector
loss,
protecting the final transistors.

5.5 TRANSMITTING
ON WARC
BANDS
As supplied, the TS-130SE will receive but not transmit on
the 3 new WARC bands.
If transmit capability is desired, a
minor wiring change is required.
1. For all 3 bands:
On the Rf unit X44-1380-00
unplug
J5 (or cut the brown wire).
2. Of for individual Bands:
On the RF unit:
