Still working out the bugs of my new linear install new at running extra power. Question is swr betwean radio and amplifier is 1.3 to 1 wich i figure is fine, problem is betwean amp and antena with amp off swr is1.1 to 1, when I switch the amp on low (variable power amp) swr is 1.1 to 1. The problem is the ferther i turn up the amp the higher the swrs get "off the chart". Have everything grounded. good power fead plenty of amps. My rig is a galaxy dx 949 peaked and tuned i run a six digit frequency counter,Willson 5000 perminent mount, and a worldwide mf 440 veriable power 1 feading 4 advertised to push from 440 watts to 850 depending on where knob is. all is connected with belden 9913f7 cable.:headbang
