KY 197A
- Panel mounted VHF Communications Transceiver
- Operates 760 frequencies from 118.00 to 136.975 MHz
- Flip-flop frequency switch to transfer between active and standby frequencies
- Remote transfer capability of remote transfer of Use and Standby frequencies and remote recall of channel frequency information
- 9 programmable memory channels in addition to the two displayed frequencies
- Non-volatile frequency storage without batteries or external battery hookup so when the radio is turned off and then back on channel information is retained
- Audio leveling automatically amplifying weak audio signals and muting those which are too strong
- 10 watts minimum power output
- 14 volt operation only
- FM immune compliant for ICAO Annex 10 (European use)
- Models available with 25Khz or 50KHz selectivity, with diffused or non-diffused display lens
- Same as KY-196A but KY-197A is 14V operation only and has lower output power
- TSO'd
