I have purchase two KG-935G Plus radios, tuned in the best weather freq for my area, which is Loud and Clear, set the alert feature to give and alarm, but neither radio will alert. Tried all of the choices, but nothing. Was told by the company where I purchased the radios that they will only alert for major events. Well a Cat 3 hurricane seemed to be a major event, still no alert. So what am I doing wrong?
