[Elecraft] KPA-1500 tuner questions

[Dave]

The problem you will run into is if the antenna SWR changes above the threshold for both the KPA1500 tuner and HF Auto bothtuners will initiate a retune and the two will be fighting each other.

 Example - ice, branches against antenna, etc.

For the bands where you need to use the HF Auto, you are better off leaving the KPA1500 in bypass.
