I recently bought a Cobra 29 LX with dual Wilson 1000 antennas. When I do a RF Output test I fail for a split second than pass right away when keying the mike, is this spike normal? My SWR is at .5 after a quick spike. Another thing is I had amazing reception yesterday after install now today its terrible. I accidently turned the SWR Cal knob up while transmitting and I got an antenna warning. After seeing this I realized what happened and recalibrated it. My main problem is I had a couple mile transmission yesterday now today barely a mile in same location and conditions.
