Every transverter I have seen out there wants a maximum of 100 mW. What do a ham do? The preferred rig is a TS-2000, currently the 6 M rig, or my faithful IC-706m2g. Don't want to put too much into it but then again don't want crap. Any ideas out there? Any info greatly appreciated.

I have DEMI 2m, 432 and 1296 transverters with 10 watt (max) interfaces. 
I tried playing around with the alc power reduction scheme, but I found 
it to be much too fussy with my FT-990. The FT-990 can be turned down to 
about 10 watts output, but I wanted something foolproof so that I 
wouln't burn something up if I forgot. I finally just used a dummy load 
into which I transmit at about 50 watts and tap a little power off of it 
to drive the 10m i.f. transverters. This works just fine and if I forget 
to turn the i.f. power down and run at 100 watts, it only results in 3 
db overdrive which doesn't seem to matter much.

On 1296, the i.f. rig is an FT-897 on 2 meters. It automatically sets 
the power output on 2 meters to 2 watts when the transverter mode is 
selected. Very handy. I don't think that Yaesu has documented this 
feature anywhere, but I have compared notes with other users and they 
all work this way.
