Thanks for your response!

The King was rebuilt in the mid 90's, and the Narco was tested in another plane, and works fine. The plane is hangered. I have looked at the contacts, and bnc connectors for the antenna's, but I must admit that I get lost in all of that wiring..... The connectors seem to be in good order....

I will check over the antenna mounts, and wiring this weekend.

Thanks!
