I was an electrical engineering major at school...there was a student run station that needed volunteers with a technical bent. I got to know several individuals that went on to the local news/talk outlet. They took me with them, but instead of being put entirely on the engineering staff...I was a hybrid...I tended the overnight operations of the station and oversaw the transmitter operations...but because I was there at 4:00 AM I was also made the producer of the farm/agribusiness/gardening show. From 4-5 AM I produced the "farm" show which transitioned to the gardening show 5-6 AM.
While at all time still working overnights, I also started to produce shows one to two days a week on Medicine, Home Improvement, NFL Football, Major League Baseball, general household "handyman" activities, Automobiles, Hunting and Fishing, and lastly (gasp) Politics.
To digress briefly from the broadcasting subject, that last genre of talk show, politics, persuaded me that Libertarians are beyond a doubt the biggest imbeciles on the planet. Do not cite Ron Paul or the Cato Institute to me...the Cato Institute is de facto the public relations department of the Koch Brothers...Ron Paul is, well Ron Paul and I have met and conversed with him many times over a twenty year period...a nice guy, I would accept social invitations from him,...but never vote for his ideas. The US tried the Laissez Faire/Social Darwinism model during the period from 1860 to 1930 and it wasn't a very nice place to live for most. Most people younger than 35 are so ignorant of history that they are unaware of this. Bringing up a close second in imbecility are the right wing conservatives.
Back to Broadcasting...
It is very much harder now as colleges that have retained their stations have converted them to professionally run organizations with paid staff with very few student volunteers.
Pay scales are best in the larger of the top ten markets...in markets smaller than the top ten pay drops precipitously.
I learned how to edit sound with tape and single edged "cocaine" razor blades...naturlich it is all digital now. A pc with inexpensive software can outperform the most expensive tape machines.
You will be a mercenary...you will be called upon to promote questionable things. the best examples I can think of are patent medicines, herbal remedies, weightloss schemes.
It would be smart to learn how to produce video as well now.
I stayed at one station for twenty years until i was laid off in 2007...I have submitted resumes to many stations both tv and radio (local and nationwide) and received only a handful of responses. I went back to my purely technical roots and have worked in telecommunications since 2007
I know this post is disjointed and wandering...I am thinking of things off the top of my head...I hope it has been edifying.
