First, good luck. You'll need it. I know that sounds condescending, but I don't mean it that way. No matter how good anyone is, everyone who has ever worked in radio, at one point, just got lucky. The telecommunications job I left in '01 for radio employed 78,000 people in a single metropolitan area of 1.5 million to 2 million people. At the time, I doubt there were 78,000 full-time on-air jobs in the entire country. Radio is a small business.
Now, what can you do to increase your likelihood of having good luck? Well, one thing I would do is look for sports. I mean live and either local or regional high school or college sports. Find stations that carry that programming and make sure they know you're interested. High school football season starts in three to four months. Start reaching out now, and keep reaching out. It's okay to reach out to stations carrying professional sports, especially with this being the middle of baseball season, but a lot of those professional games are automated now, too. You might find a small broadcaster who still runs those games manually and needs someone to push buttons, though the large companies probably don't need those people anymore.
Also, look at stations in or near your area that still have at least local talent, even if it's not live. Community or educational radio is fine, but my experience has always been that talent coaching there is lousy, and it's, at most, minimal help getting into commercial radio. I'd keep that option open, but I'd put most of my focus on commercial operators unless you just really like community or college radio. Where my mother lives, the iHeart stations are just computers and servers at the transmitter sites, but it still has two local broadcasters who do live and local. Granted, those two aren't as live and local as they were 20 years ago, but they still believe in it and still do it. Find those people, and talk to them. No matter how hard you try and no matter how good you are, you're not getting hired in anything other than sales by someone who doesn't do local programming. Unless you think sales is your thing and sounds fun, don't waste your time with those people. If you have an iHeart or Cumulus station that does local programming, it's probably worth checking out, but jobs are few there. My local Cumulus cluster hasn't added a single full-time local on-air position in 15 years, and it has very few local part-time on-air positions. If you have nowhere else to turn, get to know the handful of local employees those stations have and make sure they know you're interested. If nothing else, they'll know they have someone they can call if they need help in a pinch.
Finally, some of the best advice I ever got about getting into radio was to sell your reliability over your talent when trying to get that first job. I'm sure money was the driving factor and that it would've happened sooner or later no matter what, but radio talent is notoriously unreliable, and that undoubtedly hastened the push for stations to automate. Program directors really view reliable talent as worth its weight in gold, and that definitely got me moving up more quickly than I otherwise would have. No call/no shows were common, and every PD in the building knew Kent would pick up the phone and could likely come in during the afterhours or weekends. When I first took the job, there was talk of splitting the Sunday midday and Sunday night shifts between two people, but that never ended up happening because I was so reliable they didn't need anyone else. That also meant I had one less person in-house to compete against for the next job that came open. Granted, you open yourself up to being taken advantage of when you're that person, but radio has always been an abusive relationship. If you're not willing to hustle, take criticism, and put in long hours for low pay and no promises, it's not the business for you.
