Some users of the TS-940S have reported a blanking of the display accompanied by a loss of transmit and receive. Readjustment of the PLL unit will correct this tendency.
- Set the Dial frequency for approximately 1.8 MHz (inside the band).
- Using an RF probe at TP5 adjust L22, L23, and L24 for a maximum reading on the meter. You should see approximately 250 mV.
- Adjustment of L24 will produce the greatest change, which may be up to a 90° adjustment from its present position.
Time required for the procedure is .5 hour or less.
