Your needle not swinging on the ground would worry me. That should be
checkd out also. If you have good signal strength (on ground) then
needle should swing.

There "was" and adf in my plane before I bought it, and received the
adf in a box when I bought it. The tray was still installed in the
avionics stack, and I had a kr85 reveiver, KI225 head, and 42 loop
antenna in the box. I put the receiver back in, and had my mechanic
put the loop antenna back on the plane during annual.

I tested out the system last night. It hears AM Radio well...
It idented a beacon fine, but the needle wouldn't swing to it on the
ground.

I decided to fly and check it out. Sure enough, once I was airborne
the needle swung, and that's when I noticed my problem.


Isn't the needle supposed to point "toward" the NDB?
the head was acting more like a VOR head in the from position.
I know an NDB doesn't have radials, so why would my needle be pointing
toward the tail of the plane as I approach the beacon, and then swing
toward the prop as I pass over?


Thanks
