Providing VHF communications in the 118.00-136.975 MHz bandwidth, the TSO'd KY 97A is a 760 channel transceiver generating 5 watts minimum (7 watts nominal) of output.
Among the many key features are 'flip flop' frequency switching and built in side tone.
The KY 97A also incorporates an audio amplifier with three audio inputs, eliminating the need for a seperate audio panel in some cases. Of special interest to helicopter operators is the available provisioning for remote 'flip flop' switching.
Other pilot useful capabilities include automatic radio levelling, to boost weak signals and mute excessively strong ones, and automatic squelch override. A stuck microphone alert notifies the pilot and stops broadcasting when the transmitter has been continuously activated for more than 35 seconds. In addition the KY 97A transceiver displays transmit and receive annuciations, to verify your active COMM and alert you if any audio settings may be incorrect.
