DS-MFJ-993B MFJ-993B IntelliTuner™ (160 - 10Meters -300/150 Watts

The MFJ-993B IntelliTuner™ covers 1.8-30 MHz coverage and lets you tune any antenna automatically balanced or unbalanced - - ultra fast. It’s a comprehensive automatic antenna tuning center complete with SWR/Watt-meter, antenna switch for two antennas and 4:1 current balun for balanced lines. Power rating for matching 6-1600 ohm matching at full 300 Watts SSB/150 Watts CW
MFJs exclusive IntelliTuner™, Adaptive Search™ and InstantRecall™ algorithms give you ultra fast automatic tuning with over 2000 non-volatile revolving memories. You get a highly efficient L-network, wide 6-1600 ohm matching at full 300 Watts SSB/150 Watts CW, 1.8-30 MHz coverage, Cross-Needle and digital meters, aural SWR meter, backlit LCD display, remote control port, radio interface, heavy-duty 16 amp/1000 volt relays and more. As you are ragchewing, contesting or DXing, your MFJ-993B is learning! When you transmit, the MFJ-993 automatically tunes for minimum SWR and remembers your frequency and tuner settings. The next time you operate on that frequency and antenna, these tuner settings are instantly restored and you are ready to operate in milliseconds! Each of two antennas can learn and remember over a thousand frequencies and tuner settings. They are safely stored in non-volatile revolving memory.
MFJs 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. When the impedance is within its measurement range, the MFJ-993B is the fastest automatic antenna tuner in the world. If it cannot accurately determine impedance, MFJ’s AdaptiveSearch™ algorithm goes into action. Frequency is measured and relevant components values are determined. Only those values are searched for ultra-fast tuning. For even faster searches, you can set the target SWR to 2 (settable 1.0-2.0). You can manually tune when you cannot transmit (for listening out of ham bands).
Lighted Cross-Needle and digital meters lets you accurately read SWR, forward and reflected power at a glance. An aural SWR meter lets you hear the tuned SWR when you cannot see or read the meters. Turn on a highly visible, instant response SWR LCD bargraph when you need it. The backlit LCD displays SWR, forward/reflected power, frequency, antenna 1/2, L/C tuner values, on/off indicators and other information.
