FT-900 Pwr out...hmmm

[Nick J Chiarchiaro, AET / N2QXF]

Hi name is Nick,

I have the ft-900 and it seems to be from abt 5-100 watts output on 
ssb/cw and from abt 5-25w out on am.

After going over the supplied schematics it seems I can vary the pwr 
output range of the front panel rf pwr adjust.

The front panel RF adjust is on the SW-UNIT and is a 10KB VR#9101 
which is JP9104.  That mates with J1017 on the LOCAL-UNIT.  Into that 
circuit there is a VR1012 10KB which is listed as POSET and adjacent 
in the schem is VR1017 4.7KB which is listed as AMPO. 

I am assuming I can adjust pot VR1012 10KB POSET to adjust the 
overall pwr range of the front panel RF power knob.  I am looking to 
decrease the LOW pwr setting to 1w or below.  

I understand that if this is the case the overall MAx output would be 
less than 100w at MAX clockwise rotation of the front panel RF pwr 
control.

If anyone has the supplied schem with the ft-900 and would care to 
take a look, I would greatly apprecaite it.

tnx
nick
