mAT-30 HF-SSB Automatic Antenna Tuner 120W Auto Tuner Automatic Ham Radio for .The mAT-30 is an automatic tuner intended for use with modern for transceivers.It works with some for transceiver that supports an FC-30,FC-40 or FC-50 for tuner;a partial list of compatible units includes:FT-100,FT-857,FT-897,FT-450D,FT-891.The interface cable is included.The operating is the same as the method of for the tuner, which is simple and convenient. The mAT-30 can work within the range of 3MHz to 54MHz.The mAT-30 connects to the radio via its CAT/LINEAR jack to control the tuning cycle;the transceivers Tune button controls the tuner.The CAT/LINEAR jack also powers the tuner,so it requires no external power supply.The mAT-30 is specially engineered to integrate with for your FT-100/857/897/450D/891 HF radio.Tuning is performed when the TUNE button is pushed on the front of the transceiver and held for one second.The mAT-30 provides automatic antenna tuning across the entire HF spectrum plus 6 meters,at power levels up to 120 .It tune dipoles,verticals,Yagis,or virtually any coax-fed antenna.It match an amazing range of antennas and impedance,far some other tuners you may have considered,including the built-in tuners on many radios.The mAT-30 is specially engineered to integrate with for your FT-100/857/897/450D/891 HF radio.The mAT-30 connects to the CAT(Computer Automated Transceiver) port on the back of the radio.The CAT interface allows an external device such as a PC or the mAT-30 to control the FT-100/857/897/450D/891 by sending it serial commands.The mAT-30 takes advantage of this interface to simplify the tuning process --one button push is all that is needed in order to switch the radio to FM mode,reduce output power, transmit a carrier, measure the transmit frequency,and then restore the radio to its previous mode and power level!The mAT-30 also features advanced memory tuning,providing 16000 memory locations;when tuning near a previously used frequency it recall the settings for nearly instant tuning.It learns your favorite frequencies and bands as you use it.You can also a tuning cycle manually whenever necessary.The mAT-30 has16,000 frequency memories.When tuning on or near a previously tuned frequency,the mAT-30 uses "Memory Tune" to recall the previous tuning parameters in a fraction of a second.If no memorized settings are available,the tuner runs a full tuning cycle, storing the parameters for memory recall on subsequent tuning cycles on that frequency. In this manner, the mAT-30 "learns" as it is the bands and frequencies as it goes.Color: BlackMaterial: MetalPackage Contents:1 x mAT-30 HF-SSB Automatic Antenna Tuner1 x Connecting cableOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
