Last I looked I was required to have an endorsement on the ADF and VOR. I admit this was for NVFR but when this was fashionable you could get a Class 4 (Day), which also endorsed you.
Use of these instruments unendorsed were for Visual fiddling and you couldn't even mark them on your flight plan unless endorsed.
My Bendix T12D made it legal for me to fly above 8/8 clouds and listen to cricket scores and it always pointed to the nearest thunderstorm. A great innovation.
Pity about the Morse thing considering I nearly went mad learning to copy 10 WPM.
What's a GPS again?

Reason: fiddling whilst un endorsed on my computer.
