All, I have a gap titan and am trying to 'tune' it on 40 and 80. On 80 the center is about 3800kc; I would like to raise this to 3950. Is there a cap to do this?? On 40 the SWR is 2.8 at the low end and 3.2 at the high end. How can I adjust the SWR on 40? What are the controls and how do they work?? Thanks, Dan kb0qil
