Dave, The KPA3 will throttle back power at or above the SWR = 2.0 point. Actually, I am not certain about the K3/10 - it may or may not reduce power above SWR = 2.0,. but I would suggest that your goal for antenna tuning be less than SWR = 2.0.
I you have resonant antennas, then it should be a good thing to tune them for less than a 2-1 SWR, but if you are using a properly tuned multiband antenna, you should already have an SWR less than 2-1. If you are using a non-resonant antenna, you already have a tuner installed - just set the tuner for the lowest reflected power possible. 73, Don W3FPR On 4/4/2012 8:33 PM, David Stratton wrote: > At what point does the SWR have to rise up to before > > the K3/10 output power begins to decrease? > > I have been using a TS-830 which is not bothered by > > SWR up to at least 3:1.
