Re: 4S-Tuner SWR Red LED

I’ve noticed with mine that you can sometimes get a deeper null in tuning with a different letter setting on the dial. Be sure to try tuning the same band/antenna using a letter close to what you are currently using. Also try different combinations of your left and right knobs to get the best null.  

I keep a list of the best settings for antenna/band in the notes section of my iPhone for quick reference.
