600 Watt "IntelliTuner" Automatic Antenna Tuner
The tuner includes a highly efficient switching L-network with wide matching capability, 1.8 to 30 MHz coverage, cross-needle power meters, a port for an accessory remote control, a radio interface port, and heavy-duty 16 amp/1000 volt relays. It is rated at 600 watts PEP SSB and 300 watts CW.
192 values of capacitance and 192 values of inductance are available. With the inductance switched between the input and output side, this provides a total of 73,728 L/C tuning combinations. The nominal tuning ranges are 0 to 2950 pF and 0 to 17 µH.
All MFJ IntelliTuners™ learn and remember. When you transmit, they automatically adjust for minimum SWR and remember the frequency and tuner settings, safely stored in non-volatile memory. The next time you operate on that frequency (or close to it), these tuner settings are instantly restored and you're ready to operate in milliseconds. The tuner can learn and remember more than a thousand frequencies and tuner settings.
When you key your transmitter, MFJ's InstantRecall™ checks its memory to see if you have operated that frequency before. If so, tuning is instantaneous and you're ready to operate. If not, MFJ's IntelliTune™ 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. Finally, it fine-tunes to minimize SWR, and you're ready to operate - all in a fraction of a second.
If the antenna impedance is not within the tuner's measurement range, MFJ's AdaptiveSearch™ algorithm goes into action. Frequency is measured and relevant component values are determined. Only those values are searched for fast tuning. If it still cannot find a match, the search is performed again using a different search pattern.
The target SWR can be set at 1.5 or 2.0. The minimum power to tune is approximately ten watts. You can manually tune where you can't transmit (for listening out of ham bands). The optional MFJ-993RC Remote Control provides most tuner controls, allowing convenient remote locating of the tuner itself.
All MFJ's IntelliTuners™ support radio tuner interfaces that are compatible with Icom AH-3 and AH-4 tuners and the Alinco EDX-2 tuner. Optional interface cables MFJ-5124I (for Icom), MFJ-5124K (for Kenwood) and MFJ-5124Y (for Yaesu) are available.
The tuners enter a "sleep" mode when idle and when no transmit signal is present, turning off the microprocessor clock to avoid the generation of spurious signals.
