BULLETIN # 37
MODEL: TS-120S
SUBJECT: VOX OPERATION PICK UP TIME
High speed CW ops may inquire about partial loss of the first character
when operating VOX-CW. The transceiver will operate up to about 20WPM
before this is apparent.
Improvement may be had by changing three components on the RF Unit X44-
1260-01.
R33 100K ohm, change to 150K ohm
R52 33K ohm, change to 4.7K ohm
C62 .022 uF, Change to 1 uF @ 50v
Production later than serial # 940701 has this change.
Please make these changes in your service manual.
