I have a Arvin AM/FM clock radio model 43R43, it is having some problems. When I tune into the lower end of fm band it makes a horrible screeching noise between 88 and 94 and it has some trouble with tuning into some stations on the fm band. The sleep timer and the alarm works fine but I think it’s also supposed to have a buzzer alarm that goes off when the alarm is set and the clock trips the alarm at the time it is set for.
