If you read the saved code plug, you would see KEY123456789. If you read the radio, you would see KEY*********. What good would encryption be if a 3 letter agency, or soldier lost his radio, & the enemy found it, read it, & knew the key. Now DMR radios are not used by 3 letter agencies, or the military, but long ago we used System Sabers with DES-XL, & a 3011DX key loader. When the battery needed to be changed, you had 30 seconds to change it, or lose the key. But if a soldier knew capture was iminent, he would remove the battery while the radio was on, & the key was instantly wiped from the radio. Newer radios allow you to choose to keep the key if no battery is attached.
