As you saw, it simply shields the radio from everything. A better way is to turn the radio in different directions. You can often can null an offending station by pointing the side of the radio toward the offended or interference. If you have a kitchen-type Lazy Susan around, set the radio on it and try. It only needs to turn in that plane, though sometimes tilting it from side to side can help. Probably easier to do than explain.. > I had an odd thing happen the last two nights.

A mystery. Best pickup for most portables is in the direction of front/back. They have a figure 8 pattern. > Sean, who is getting the impression that just having a Superradio II > doesn't quite cut it on this group :) You can pick up a lot with that. It's not so much the equipment, as being in the right spot at the right time. There was a guy who used to DX quite successfully with a crystal radio. Linodyne circuit, if memory serves.. Glad to see you, and hope the list is useful. I'm not anyone official to the place, just one of the denizens..
