In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.

In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.

This does not pertain to the comm selector channel spacing.

With the evolution and growth of airborne travel and the necessity for more usable frequencies in the VHF communications spectrum, the "channel" spacing became smaller. To avoid interference between channels the bandwidth of the RF stages was decreased from 50khz to 25khz. In doing so, another problem was introduced. If the ground transmitter or the air to air transmitter was not capable of tighter frequency tolerances, it was possible the 25khz RF selectivity would not allow the receive signal to pass and the aircraft crew could miss critical voice communications.

Due to the presence of older, outdated equipment in some countries, some manufacturers (namely Bendix/King and Collins) produced VHF comm radios with the 50khz receiver selectivity. With the recent mandates and technological advancements in Europe and South America, the requirements for the 50khz versions has diminished. If an operator were to use a 50khz version radio in the position of a 25khz, they would potentially have channel crossover and or an increase in background noise.
The A models superseded the original models. The A models include all of the upgrades that were available via Service Bulletins for the KY-196/197. These improvements include the following:

  • Expansion to 760 from 720 (i.e. 135 to 136 MHz)
  • 9 channel memory
  • Remote frequency transfer capability
The products improvements in the A models include some technical and production improvements which enhance the overall reliability of the radio. The A models utilize a different mounting rack than the original KY-196/197 radios.
Navigation (Nav) and Communication (Comm) radio receivers and transceivers are available as separate, individual radios or as a combined Nav/Comm unit.

A Nav/Comm unit is sometimes more economical in price than the 2 separate Nav and Comm radios and usually requires less panel space.

Obviously, one disadvantage to the combined Nav/Comm unit is in the case of unit failure you lose both nav and comm functions since the entire unit is removed.		 KN-53 Nav:

Negotiating the exchange price of a unit only limits the allowable repair cap for the core unit. Southeast Aerospace's exchange transactions are based on the return of economically repairable core unit. Once the core is received and evaluated, the core repair cost incurred by SEA cannot exceed 75% of the original exchange price. That is, it cannot cost SEA more than 75% of the original OH/SV exchange price collected from the customer. Therefore, when and if an SEA exchange price is discounted, there is a risk that additional charges may be assessed once the core is returned and evaluated.

The part number for the terminal contact pin that is used on most Silver Crown units is 030-01107-0000. Previously, Honeywell (Bendix/King) offered them in preset amounts based on the unit that were being used with (ex. 030-01107-0064 for the KX-155). Currently, you simply purchase the amount of -0000 pins required.

As of 2010, the List Price for each contact pin is $5.98. Therefore, in most cases, it is less expensive to buy the entire unit installation kit.
