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.

The KX-155 and KX-165 LED display upgrade involves more than simply changing a display assembly as it was with the original gas discharge displays
manufactured in the KX-155 and KX-165 radios.

Yes. Southeast Aerospace recommends that Service bulletin 1 and 2 be complied with on the KA-120 when the adapter is being installed on a new installation.

Service Bulletin 1 corrects an impedance mismatch between the new generation KX-155 and KX-165 Nav/Comms that utilize surface mount technology. KA-120 with serial number 1845 and above have Service Bulletin 1 incorporated during original manufacturing. The cost to add SB 1 is approximately $200.

Service Bulletin 2 corrects a serial tuning bus incompatibility when interfacing the KA-120 with a KX-125 and with new generation KX-155 and KX-165 surface mount units (post Mod 16 units). KA-120 with serial number 2819 and above have Service Bulletin 2 incorporated during original manufacturing. Honeywell does offer warranty credit for any KA-120 S/N 2818 and below that requires this modification. An authorized Honeywell Service Center must perform the modification and submit the warranty claim.
None, they represent the same unit. Original King Radio part numbers were 9 digits. For example, 066-3056-01. During the Bendix and King merger (i.e. Bendix/King), a new part numbering system was created that converted these 9 digit part numbers to 12 digits. Therefore, 066-3056-01 became 066-03056-0001. Despite this numbering change, units that were originally from the King Radio design still have the 9 digit part number format on the unit dataplate. The 12 digit format for King units appears to be used for catalog and internal Honeywell purposes only. Therefore, any unit that has a zero in its third to last number (i.e. XXX-XXXX-X0XX) has a 9 digit part number (i.e. XXX-XXXX-XXX) on its dataplate / ID Plate.
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 smaller concentric knob on the Nav side of the KX-165 has a PULL RAD label on it. When this knob is pulled, a radial mode for the KX-165 is enabled where the right hand window of the NAV display indicates the bearing FROM a station. In addition, a digital warning flag is activated when weak signals are present. Also, when an ILS frequency is selected, the digital flag is displayed in the radial window.
In January 1989 Bendix/King changed from a nine digit to a twelve digit part numbering system. The new, larger 12 digit numbers allowed for the inclusion of software version into the last two digits of the part number for certain units in which software changed frequently such as EFIS and TCAS processors. Therefore, the two digits immediately preceding the software version indicate the hardware version of the unit.

Different software versions imply different operational features and/or interface capabilities and software modifications imply software repairs (bug fixes) to insure proper operation of these features and interfaces. Software version upgrades frequently require hardware modifications to the unit. Such hardware modifications accompanying software version upgrades do not necessarily change the hardware version of the unit.
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:

While there are many indicator options for the KX-165, the more commonly interfaced indicators include the following:

(VOR/LOC only)
KI-202

(VOR/LOC Glideslope)
KI-206
KNI-520

(HSI)
KI-525A
KPI-552
KPI-553A

(RMI)
KI-229

There is no Service Bulletin that approves the modification of a KX-155 to add a VOR/LOC converter. The main PC boards in the KX-155 and KX-165 are different thus allowing for one to have converter capabilities (i.e. KX-165) and one to not have this capability (KX-155). Any KX-155 that has a VOR/LOC converter board is a Suspected Unapproved Part (SUP) and should not be installed into a certified aircraft.

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.

A power converter or booster is required to provide enough power to increase the 14 volts from the aircraft to 28 volts to operate the KX-155. The max amperage needed is 6.0 A for the transmit portion of the KX-155 and KX-165. Therefore, we recommend the Ameri-King AK-550-6.
