Bendix-King KY-197A VHF Transceiver
For component avionics, you can’t make a better choice than our Silver Crown Plus COMM transceivers, the KY196A, KY196B and KY197A. The 28-volt KY 196A delivers 16 watts minimum transmit output power, supporting a frequency range from 118.00MHz to 136.975MHz. Its 14-volt counterpart, the 10-watt KY 197A covers the same range to provide 760 COMM channels. The 28-volt KY 196B takes coverage a step further, meeting the ICAO EUR Region’s 8.33-kHz channel spacing requirements, offering a display range of 118.000MHz to 136.990MHz and providing a total of 2,280 channels.
For example, the active frequency is clearly distinguishable from the standby frequency, with both displayed in separate, dedicated windows. This allows you to preselect the standby frequency while you continue to use the active frequency. Optional remote mounted switches can also be installed on your aircraft’s yoke or cyclic to facilitate frequency management. These switches enable you to actuate the flip-flop function or call up any of the unit’s nine pilot-programmable memory channels without repositioning your hands.
The total frequency storage capacity is actually 11, including ‘USE’ and ‘STBY.’ All three units’ memory channels are especially useful for preprogramming the frequencies you use on an everyday basis - ATIS, ground control and tower, or the ones you use on repetitive routes. All 11 frequencies are held in nonvolatile storage, so no batteries or external power are needed. Other special features include audio leveling, which automatically amplifies weak signals and mutes strong ones to provide a more consistent volume level. The stuck microphone indicator shuts down the transmitter and flashes the display if the mike is keyed for more than two minutes. (This prevents you from inadvertently jamming a frequency and making it unusable for other pilots.) There’s also a ‘Program Secure’ mode that lets you lock a specific frequency into a specific channel number, so the program can’t be changed from the panel.

Brilliant! Brilliant! Brilliant! What service!!
My GPS went wrong. After a phone call you got me a replacement and took my faulty unit back via courier. All within 24 hours. I just couldn't ask for better service.
Please thank the lady I spoke to on the phone, she couldn't have been more helpful.
This takes all the worries away from mail order.
