Thanks Mike. After 24 years layoff from flying I was so lucky to fly an Arrow similar to my own, like riding a bicycle and immensely enjoyed. However, I was mystified by its new electronics such as Garmin, as I am today by my wife's iphone.
Reading this sad report I hear again my dear friend and instructor Desmond, Catalina instructor from WW2 and later Cranwell QFI. "Never mind the erratic ADF Mike, just FLY the damn thing. Never trust a black box, remember that a black box can't see out and has no fear anyway". For box read tablet.
