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 _______________________________________________ VHFcontesting mailing list VHFcontesting@contesting.com http://lists.contesting.com/mailman/listinfo/vhfcontesting |
