I would like to purchase an automatic tuner for my 7k. I have selected the MFJ-939I and the MFJ-993B.
I would prefer the latter, as it is way more versatile. However, as far as I have understood, when I change frequency, the 939I tunes up without the need to push the "tune" button, while the 993B requires button pushing.
Have I understood well?
Any recommendations for a good tuner?
