Hi Speedy.

How is your health, you had issues, right? Anyways, I hope you are doing ok.

I got this last night:

And it works! It has connections for external speaker, gramophone, antenna and earth(Ground). The connections are just small round female ports, looks like male "Banana" plugs will do the trick.

The question: What do I use for an antenna? Right now it has a metal pin/screw sticking out of the antenna connector, and when I touch this reception improves, but so does static also.. Do I need to use bare copper thread of a certain length? I thought of running it around the edges of my windows on the outside, I'm on the first floor in a city block.

How should the antenna be connected? As a loop from the antenna connector to the ground ditto?

I have one of those Am wound loop antennas that comes with modern stereo equipment, not very good at anything but better than nothing..

The two stations I managed to tune in was very weak, barely audible, touching the antenna connector improved this.

Thanx in advance.

Jørn.
