I was an electrical engineering major in school. I broke into local radio in Houston without finishing school and worked at a news/talk station for 24 years. I produced call in shows on a wide variety of subjects(agriculture, gardening, medicine, politics, home improvement, sports) and worked in master control, and after 24 years I was laid off by a famous and widely vilified broadcasting company. I got a job with a small telecommunications company installing microwave links between Verizon cell phone sites. nine days short of one year on the job I was laid off again in February. I have been unemployed since then and have had no luck getting any sort of job...so yeah I have changed careers.
