Here is a photo of my model 15 (thanks to W8FIX), which I work on in the basement. It is working very well now thanks to the kind help of several Greenkeyers.

On the wall is a 16 jack patch panel (again thanks to W8FIX.) I rewired and repainted it.

The top row is my test loop. The second is my RTTY repeater monitoring loop. The third used to be ITTY autostart and is now a second test loop. The bottom used to be ITTY news and is now my newsforkids loop. These exactly correspond to a similar patch panel in my radio building.

The two electrical boxes below each have three 3-cicuit jacks. The left one can be patched to any loop on the 2-circuit patch panel. The box itself id grounded. The right one is a local loop powered by a loop supply in the rack below the 15. The meter on the wall and the one beside the 15 can be patched into any of the loops.

The 4 X 4 inch outlet box has the lower outlet always on for the loop supply.

The upper outlet has an SPDT, center off toggle switch and a 24VAC relay inside. The 15 is plugged into the upper outlet. It can be switched on, off  or connected through the relay which is operated from the idle line motor control in my radio building.

The duplex outlet with yellow romex is AC power coming to my test setup.

The patch panel is wired with cat-5 to my den/ham shack upstairs and through more cat-5 over to my radio building.

Now that that 15 is working (and it was not easy), I very badly want another.

If anyone wonders, the tape machine on the left is a stereo Scully 280 I had been trying to get working. But I lost interest when I went to digital recording. I don't care if I ever record on tape again. I have had too much of aligning tape machines every week when I worked for recording studios!
