TS850S Audiolevel in CW mods
from 17020_SM4TYA by SM4OTI

Hello everybody!

If you'd like to be able to adjust the volume with your "MONI-knob" on
the frontpanel of your TS-850S when monitoring your transmission on CW read
this! Originally it's a fixed level controlled by VR5 internally.

This could be usefull when switching between the loudspeaker and the
headphones.
When you're monitoring your CW with headphones at a pleasent level, and
then disconnect the headphones and monitoring with the loudspeaker the audio
is quite low.

(IF-UNIT)

- - Remove the IF-UNIT (you must solder on the rear side of the
IF-UNIT).
Be carefull to mark all the cables before you remove them!!!

- - Remove R239 (330 kohm, frontside of the IF-UNIT, close to VR5).

- - Install a new resistor (330 kohm) from the output of VR5 to the
point where R229, R230, R231 and C172 meet each other (rear side of the IF-UNIT,
close to IC7).

- - Adjust VR5 to maximum audio level.

Now you're able to adjust your audio level in the CW mode with the
"MONI-knob" at the frontpanel of your transeiver.

That's all there is to it!
