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.
