I am having a feedback or some kinda issue with the speaker. Appearantly anyone with better hearing than me can hear it and is very annoyed by a high frequency whine. I moved the radio, I opened the speaker etc... the only thing I can do is put a small piece of a napkin over the speaker to filter the whine. Ideas are welcome. I'll be a Danville so please help if you know what it is. Otherwise I appologise in advance for any nausea you may experience from the noise.
