My ADF (Narco 841) quit pointing shortly after I got the plane, so
I pulled it and found it was covered in swarf (metal shavings) so I
cleaned it off, cleaned the contacts (card edge connector) and put
it back in. Now it points again. What I'm wondering is: How fast
should it point? Let's say there's nothing on freq 200 (default)
and I tune a nearby NDB/marker on standby and hit swap. How fast
should the needle point? I realize that in flight it doesn't have
much call to move quickly, but until now I was never paying attention.
