I wasn't sure whether to put this under mobile or base. I am using a Galaxy DX-959 with a Imax 2000 antenna as a base. My swr is 1.2:1 on channel 1 and 1.3:1 on channel 40. When I dead key the mic, the meter goes to <1. This same radio does not do it in my Silverado with a Predator 10k. I tried another DX-959/RFX-75 on the Imax and the meter works fine. Anybody have any clues as to why this might occur?
