I use the peak reading Daiwa watt meter as well as the Peak reading watt meter in the Palstar AT5K tuner to keep the output to 1500 watts at which the DX-2SP just loafs along. It'll run continuous 1500 out on digital 24 X 7 with out worrying about over heating.
I switch to the antenna analyzer adjust the AT5K for R=52, X=0, then tune the DX-2sp into the dummy load, and then switch the station to the antenna ready to go without putting a signal on-the-air.
