On my Radio Shack® Synthesized World Receiver why do I get a whistling sound on the shortwave frequencies? Its loud and annoying and I can't figure out how to get it to go away. No outside antenna hooked up and nothing has changed.
so I don't think it's that. Just check that there is no other antenna connected, a whip perhaps even if it is pushed down. SW only is a clue - does it do it on the BC band?No outside antenna hooked up and nothing has changed.
I changed the batteries and it worked. The low battery indicator wasn't on so I didn't think to check those. I guess I need to find a power adaptor for it.
