    - "switchable ratio Un-Un (unbalanced to unbalanced transformer), that allows step-up or step-down radtios of 3:1, 6:1, and 9:1. The centre position gives a 1:1 ratio. "

     "Operation:
      The MFJ-914 Auto Tuner Extender is easy to use!
      First, bypass your transmitters auto-tuner.
      Then, while transmitting at a low output power, adjust the knob (from position A through G) on the MFJ-914 until you see minimum  SWR on your transmitter.
      Now you're ready to autotune." ---> mehr
