TS440 SSB Power-adjustment

The last few weeks I've seen questions of how to make the power in SSB mode for the TS440S adjustable without changing the Mic-
Gain. It's a very easy job to do.
Take off the top cover of the rig.
At that moment you have a sight on the first unit (IF-Unit)
Than you have to look for Diode 49.
You will find Diode 49 at about 5 CM from the backend of the unit and about 6,5 CM from the leftside of the unit.
Just next of C138 and between plug 38? (red/orange wires) and plug 26 (black-cover/blank wires) Just cut that Diode 49,bend one
part a little away and leave the part's where they are. It's the best way to do I think.
Replace the topcover.
From now on it is possible to adjust only the power in SSB mode by just turning the CARRIER Control at the front of your rig and leave
the Mic-gain for where it is.
Turning counterclock will minimize the power until a 20mW or something like that.
Because most TS440 users have'nt used their carrier control that much I think it's better to pull off the MIC/CAR knobs and spray
some contact cleaner in the shafts. (I know,it's not the best way).
When you switch your rig into the CW mode you can adjust the power in what you like,switch the mode in to USB or LSB and if it is
correct the power will not come above the level that what you have adjusted in the CW mode.
Just simple , is'nt it?
Of course you will do this all in your own responsibility because I won't take any!!! Agree?
