Okay, I should probably know this, but it's the first time I've run across it.
I have a really nice FADA 205. I replaced the caps and injected a signal. So far so good.
However, the loop antenna was hanging by one wire. I've tried a couple of different ways to hook it up, but I'm missing something.
One winding measures about one ohm, and the other almost a short.
I'm smart enough to know that one coil is larger than the other, but I can't find any info on which one goes where.
I figure this should be embarrassingly simple, but I'd appreciate any help.

Terry: If the schematic is any indication, it looks like the smaller winding is on the antenna side. But, I'm guessing that may not be what you are asking. Mark from Kalamazoo

You're right, and now that I think about it, that's true. It is, after all, a transformer. There are a couple of connections that are weak and might break, but removing a few inches of the winding should be okay. The radio is very nice. When I get it up and running I'll post a photo.
Thanks

Forgive me if I state the obvious, but you have to disconnect one end of a winding to see if it is open or not. Other than that the schematic should tell you how the loop is connected.

The antenna is good. In fact it's in front of me on the bench right now. I know that one side connects to a grid in the 12SA7 converter, and the RF section of the tuning cap. The other end connects to various points such as the IF transformers and one of the diodes in the 12SQ7 detector. What I can't figure out from the schematic is how it connects to the Osc section of the tuning cap. I've pulled another set apart and it's setup is nothing like this.
I always hate to flaunt my stupidity, but here I am.

Oops! I forgot to mention that the set works great, except that one of the antenna leads was missing. The only time that I got a signal was when I put my finger on the tuning cap.
