(2) Remove the dial pointer and old dial cord.
(3) Tie end of new dial cord to one end of dial spring, connect other end of dial spring of bottom right eye inside dial
drum, see Fig. 14.
(4) Rotate the tuning capacitor dial drum to it’s maximum counterclockwise.
(5) Run the dial cord through the slot in the rim of dial drum.
(6) Guide dial cord under and around rollers A, B, C and D. Keep the dial cord taut during this procedures.
(7) Pull dial cord taut and wrap 2 turns counterclockwise around tuning shaft. Refer to Fig. 12.
(8) Guide dial cord around roller E.
(9) Guide dial cord under and around the dial drum and wind 2-1/2 turns counterclockwise, see Fig. 14.
(10) Turn the tuning shaft to rotate the dial drum fully counterclockwise and fully clockwise to distribute the tensioning
along the dial cord.
(11) Place the dial cord over and under the tabs on the rear of the dial pointer and place the dial pointer on the top of the
dial panel rail. Refer to Fig. 13.
(12) Turn the tuning shaft clockwise. Slide the dial pointer to ZERO (0) calibration marker on the logging scale while
holding tuning shaft fully clockwise. Cement the dial pointer to the dial cord to prevent the slippage. Allow cement
to dry thoroughly.
(13) Check the dial calibration. Refer to FM/AM Alignment Procedures on page 9.

Tracking and Sensitivity
Precaution: No adjustment is required. The tracking and sensitivity has been adjusted properly and completely at the
factory. If any special reason occasioned, take the following procedures very carefully:
AC VTVM
RF Generator
Oscilloscope
Fig. 22
Low Frequency
1. Connect an RF generator to the antenna terminals on the rear panel through a dummy antenna.
2. Set the RF generator to 88 MHz, a modulation of 1 kHz and a deviation of 75 kHz, to provide an input of 2 nV.
3. Connect a VTVM and an oscilloscope to the Rec. Out Jacks on the rear panel.
4. Set the dial pointer to 88 MHz.
5. Adjust three coils L103, L102 and L101 in the tuning gang to maximize the output.
High Frequency
6. Set the RF generator to 108 MHz, a modulation of 1 kHz and a deviation of 75 kHz, to provide an input of 2 uV.
7. Set the dial pointer to 108 MHz.
8. Adjust the FM trimmers TC5, TC3 and TC1 in the tuning gang to maximize the output.
9. Repeat these high and low frequency adjustments alternately until maximum sensitivity is obtained.
