I have a QRP rig (Mountain Topper) and a variable capacitor QRP end fed half wave antenna with an SWR LED indicator. The LED doesn't go fully out in all configurations but there is always a local minimum on the knob.
Can this problem be fixed by changing the wire length? I would think so if the LED was most dim on one extreme of the knob, but since it is in the middle, I am doubtful the length can make it any better—only positioning. I am not sure though.
Can I tune an antenna wire length with this LED alone? How?
I have an antenna analyzer but it is broken right now so I am trying to do without. 73 73 73
