Johnny --

I know the transverter output is on the ICOM 756 PRO II is -20dBm//22mv 
(0.01 mw) when the power level is minimum and
about -1.5 dBm (0.707 mw) or so when it is maximum.  You must enable the 
transverter mode by apply a positive volage (2 to 13.8 vdc) to the ACC (ACC2 
pin 6) jack.  I have not measured this on my ICOM 7800 (not at home QTH this 
week) -- however the ARRL test of the ICOM 7800 measured the transverter 
output at -3.3 dBm (.46mw) on 10 meters.

Typical ICOM manual onlys give the lower limit which is the same for the 756 
Pro II and 7800.   So the 1 mw setting should be OK.
