[R-390] R-390 misbehaving

[Steve Hobensack]

Tony, 

Be sure a slug rack is not hanging up or wedged diagonally. Years ago I had a nearby lightning strike zorch the cardboard coil form in the first antenna coil. The cardboard seized the slug, preventing it, and the rack from moving. All racks should move freely and remain level. Check that all slugs are properly attached to the wire hangers. Also, put the dial on 7+000. All the egg shaped cams should point to a scratch or paint mark. This shows that the clockwork is aligned. You might put a frequency counter on the pto output to see that the frequency does not suddenly jump to something strange.

> We've had a lot of lightning in the area lately so I've had my antennas disconnected. I plugged everything back in this morning and started tuning around. I found that the background noise drops off rapidly as I tune above 950 on all bands. Oh joy. The only thing that comes to mind for all bands is the PTO. I will pull the cover and check it. Has anyone seen this symptom before? I had the front panel off about 2 weeks ago to fiddle with a couple of the gears. Maybe a connector is not seated somewhere...
