BULLETIN # 857
MODEL: TS-830S
SUBJECT: TS-830S Transmitter "Talkback"

Transmitter "talkback", either with or without a linear amplifier, may 
be eliminated by adding a filter at the receiver audio power amplifier.

On the AF unit X49-1140-00 at Q4, cut the 12V DC B+ line between R47 and 
C28, and add a luh choke (L40-1092-02) in-line. Add a .01pF cap (C52-1710-36) 
from the IC pin 1 to ground, using a 3mm lug (E23-0015-04) under the 
IC mounting screw on the Heat Sink.

Note: Installation time for this procedure is 1/2 hour or less.
