I would like to see it. I have a linear one from the US Navy. It has a Mercator map with a transparent slide. You move the slide to the satellite longitude position, find your position through the transparency, and then read the elevation and azimuth angle from the slide markings.

At the flea market in St Petersburg (Russia, not Fla!) this August I bought a Russian ex-ship "Oscarlocator"- type device for geostationary satellites in the Inmarsat series.

It's a map of the world with the satellites marked on it along the equator, and a transparent plastic overlay from which you can read the az and el to the satellite from your position. It rotaes around a central screw.

Obviously it'll work with any geostationary satellite once you have drawn it in.

I have scanned all 3 components - map, overlay and Russian text - and translated the text. I sent it to amsat-uk for their bulletin but I don't think they are interested. Maybe nobody is. But if anyone is, let me know and I'll post it on my website.
