Until the used market completely dries up, you can still find someone who will sell you a KR-85. The KR-85 may have been a cost effective, reliable unit at one time but unfortunately its time has passed. Most old avionics units become increasingly challenging to repair as the manufacturers discontinue support and cut off the supply of service parts. Likewise, even if you can find a KR-85 in working condition, it usually has little or no warranty.

Instead of continuing to invest your money in obsolete technology and delaying the inevitable, Southeast Aerospace suggests upgrading to the KR-87 ADF. Investing in the KR-87 will provide you with an ADF that includes warranty and support for many years to come. Plus, since the KR-87 is smaller it will free up valuable panel space in your aircraft.
