When I bought this from ebay awhile back, I checked on the mods. It
supposedly has 1-4 and 6-11 (I don't have it here in front of me). It just checked
out in June on the IFR certification (go figure!). I'm guessing it's one of the
connectors on the back.

It could be in the radio, but I doubt it's a bad VOR receiver/converter, since
the RNAV works. I think the radio's just not getting the right X/Y encoder signal
from the OBS knob, so it doesn't know where to put the needle.
