I have been running a Galaxy DX-979 with variable power and open clairifer that I love from DTB. Rock solid and staible. I have a TS-350 I was going to run with this radio. Set the power on the raidio to 1-2 watts etc but my question is can I run the amp on variable power to the desired wattage is obtained or should I run it set to variable power and the control set to wide open I am told this will run the amp at 50% power ( set to variable and knob wide open) not shure how the variable power works buy i read leave it wide open or it will over heat and burn.
