Oh! thank you thank you, I can't thank you enough. I have been wondering for months how I could stop these dreadful voices.. yes OK I'm doing it, be quiet. Give me cake, I want cake. Is this a dagger I see before me, its' handle toward my hand. I cannot wait, so when I've been I will make one and these evil voices, yes you, will be FOILED.. Taa Raaaah
Probably stray pick-up from local police/taxi transmitters. If you listen carefully you may be able to identify the source. Suggested cures, re-route the speaker leads, make sure you have good quality leads for speakers and other attachments, because pick-up can occur on ANY lead. Try disconnecting things to see if it disappears. Good luck and if the voices tell you to kill someone, AAGGHHH !!!!
