World’ s First dual power level 300/150 Watts SSB/CW Tuner
Select 300 Watt SSB/CW power level and match 6-1600 Ohm antennas Or . . . select 150 Watt SSB/CW power level and match extra wide-range 6-3200 Ohms!
The MFJ-993B IntelliTuner lets you tune any antenna automatically balanced or
unbalanced — ultra fast.
It’ s a comprehensive automatic antenna tuning center complete with SWR/Wattmeter, antenna switch for two antennas and 4:1 current balun for balanced lines.
MFJs exclusive IntelliTuner, Adaptive Search and InstantRecall algorithms
give you ultra fast automatic tuning with over 20,000 VirtualAntenna Memories.
You get a highly efficient L-network, 6-1600 ohm matching at 300 Watts SSB/CW
or extra-wide 6-3200 Ohm matching at 150Watts SSB/CW, 1.8-30 MHz coverage, Cross-Needle and digital meters, audio SWR meter, backlit LCD, remote control port, radio interface, heavy-duty 16 amp/1000V relays.
It learns while you’ re having fun
As you’ re ragchewing, contesting or DXing, your MFJ-993B is learning!
When you transmit, the MFJ-993B 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’ re ready to operate in milliseconds!
MFJ new VirtualAntenna Memory system gives you 4 antenna memory banks for each
of 2 antenna connectors. Select up to 4 antennas on each antenna connector. Each antenna has 2500 memories, 20,000 total.
Intelligent ultra fast tuning
MFJs InstantRecallTM first checks its memory to see if you have operated this frequency before. If so, tuning is instant-aneous and you’ re ready to operate.
If not, MFJs 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 can’t 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 can’ t transmit (for listening out of ham bands).
Cross Needle and Digital SWR/Watt Meters
Lighted Cross-Needle and digital meters lets you accurately read SWR, forward and reflected power at a glance.
An audio SWR meter lets you hear the tuned SWR when you can’ t see/read meters.
Turn on a highly visible, instant response SWR LCD bargraph when you need it.
