Product Description

The KT-70 is a technological step up from the popular KT-76 series of transponders. Unlike these Mode C transponders, the KT-70 is also capable of Mode S operation. In fact, the KT-70 was the first panel mounted Mode S transponder.

Mode S stands for "selective", and it is helpful for both the pilot and controllers. A Mode S transponder is uniquely identified, and can send this identity data. This allows the ATCRBS system to call a transponder individually (selectively), reducing bandwidth needs in crowded airspace. Mode S transponders are not yet required, but like Mode C in the past, that day is coming.

With 250 watts of transmission power, the KT-70 offers long range and operation at any altitude. It also takes the same amount of panel space as a KT-76 series transponder, permitting upgrades without moving other radios. (The KT-70 is a new installation, but you won't have to make space for it.)

The KT-70 features:

  • Self-dimming gas discharge display
  • Displays the ATCRBS code and encoded altitude transmitted
  • Push button selection of VFR code (1200)
  • 250 watts of power
  • Supports a remote ident button
  • System self-test function
  • TSO'd
