The problem is full output both forward and reflected on 20 and 17
The modification is made after read ''TS-120S TX ocillation'' of 19/07/98
- remove up cover (8 screws)
- remove the ''relay unit X41-1300-00'' (2 screws)
- remove the screw under the ''relay unit'' on the ''RF unit X44-1380-00'' just near the coil L48. Put a terminal and replace the screw. The terminal is now to the ground.
- solder a 10nF ceramic between the terminal and the coil L48.
- replace the ''relay unit'' and the cover.
