What is the difference between the King KNS-80 and the King KNS-81?
The KNS-80 contains an internal DME, while the KNS-81 does not. While the KNS-81 is less expensive initially, by the time you add the required KN-63 DME system, it becomes significantly more expensive. Most of our KNS-81 sales are to customers who are replacing an already-installed KNS-81. These customers already have the KN-63 installed, so that is no longer a price factor.
