All:

Has anybody tried using the trick of applying a negative voltage to a 
FT-847's ALC input to reduce power to drive a transverter?  This 
technique worked really well with my IC-756 with only -1.5V applied, but 
applying even -4.0 volts to my FT-847 didn't seem to make any difference 
at all.

I'm trying to use a Downeast Microwave "Transverter Interface Box" (TIB) 
to provide the negative voltage to cut back the 144 MHz power to my 903 
MHz transverter when I enable the transverter.

TIA for any advice or observations.

73, Dave/K8CC
