BULLETIN # 900
MODEL: TS-940S
SUBJECT: PLL Unlock 


Some users of the TS-940S have reported a blanking of the display
accompanied by a loss of transmit and receive.  Re-adjustment of the PLL
unit will correct this tendency.

PROCEDURE:

On the PLL unit

1.   Set the dial frequency for approximately 1.8 MHz (inside the band)
2.   Using an RF probe at TP5 adjust L22, L23, and L24 for a maximum
     reading on the meter.  You should see approximately 250mv.
3.   Adjustment of L24 will produce the greatest change, which may be up to
     a 90 degree adjustment from its present position.

Time required for this modification is 1/2 hour or less.
