As a physics professor I'm acutely aware of the measurement problems you describe! 73, Stephen G4SJP On 13 May 2011 20:54, Jim Brown <[email protected]> wrote: > On 5/13/2011 12:21 PM, Stephen Prior wrote: >> I have only just noticed that on 6m only, the maximum power output >> that can be dialled up is 106W. 110W on all other bands. > > I would be VERY VERY interested in how you can reliably resolve the > difference between 110 watts and 106 watts, or even how you're certain > it's 106 watts.
