  • 1.3" high flat-pack, DME unit
  • 200-channel receiver
  • Features simultaneous gas discharge display of distance, groundspeed and time-to-station
  • Can be channeled through almost any NAV receiver or tuned directly with its own frequency selection knobs
  • No remote channeling adapters needed
  • All channeling done electronically using a single crystal digital frequency synthesizer
  • Operates on any DC voltage from 11 to 33 volts without adapters or power converters
  • No external cooling is required since it draws only 15 watts of power
  • Same as KN-62/62A except has 50 watts nominal power output instead of 100 watts for KN-62/62A and KN-64 is not TSO'd, while the KN-62A is TSO'd

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 data bus for the KDI-572 /573/574 indicators is available from the KN-62/62A/64 but there is no 192 volt output from these DME units to light the display of these DME indicators.
The differences between the KN-62, KN-62A, and KN-64 units are the TSO and output power ratings. The KN-62 is not TSO'd and has 100 watts nominal power output. The KN-62A is TSO'd and has 100 watts nominal power output. The KN-64 is not TSO'd and has 50 watts nominal power output.
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.
Yes, but in most cases, the DB30 adapter from Garmin AT is necessary. The SL30 does not output a standard DME format in relation to most vintage and standard DME systems. The DB30 takes the format from the SL30 and allows for the interface to King and Collins DME units. Some of these interfaces include BCD, 2x5 code, and Slip Code. It should be noted that the DB30 2x5 tuning interface is not compatible with the ARC/Cessna RTA-476A or Narco DME transceivers.
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.
While external suppression should be connected when a GTX-327 is installed into an aircraft with a DME, the GTX-327 suppression input/output is not compatible with the Bendix/King KN-62, KN-64, and KNS-80. These DMEs have an output only suppression port and can be damaged by the GTX-327 mutual suppression output. Therefore, the suppression pin should be left open. If the suppression line is connected between the GTX-327 and above King DME units then the DME will appear to be inoperative, display will be blank and will not transmit.

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.

Even though the KN-62 is a higher power DME, supply and demand factors relate to the market pricing for the KN-62 vs. KN-64. In addition, the KN-62 is an older unit and therefore has reliability factors that need to be considered.
