Intelligent Ultra-Fast Tuning

MFJ’s InstantRecall first checks its memory to see if you have operated this frequency before. If so, tuning is instantaneous and you’re ready to operate. If not, MFJ’s IntelliTuner algorithm -- based on MFJ’s famous SWR Analyzer technology -- kicks in. It measures the complex impedance of your antenna. Next, it calculates the components it needs and instantly snaps them in. Then, it fine tunes to minimize SWR -- you’re ready to operate. It’s all done in a fraction of a second.

As always, with high power, consider double-checking your radio station grounding plans and always follow the ARRL RF Guidelines. Learn more here:
