I remember wanting a full time career in radio at one time many years ago. I was in the Air Force during Viet Nam as an Aircraft Electrician (while stationed in Alaska at Eielson AFB I worked part time on AFRN- Alaskan Forces Radio Network), and while stationed in Portsmouth NH I worked part time at WBBX (the station was owned by ABC Wide World of Sports sportscaster Kurt Gowdy, whom I met one time when he was in town and dropped in for a quick visit). I met some great guys. A couple of them had actually worked in the Wilmington / Philly markets at WDEL, WIP, and some other Philly area stations, and yet were in a small market of Portsmouth NH. They all told me that they've been all over the country up and down the dial over the years (remember most don't get pensions as they don't stay at a station long enough to earn one). A majority of them were divorced. They said radio hadn't been a good thing for their marriages due to the lack of roots as they moved every time a station changed its format, it changed it jocks. Also depending on how large the radio market is will determine whether or not you'll be able to make ends meet with your radio salary. I knew many radio guys who worked in one market during the week and another one on the weekends or some other part time job to supplement their weekday radio pay check.
Later, after I had gotten out of the Air Force, and was thinking about getting married, I decided that moving all around the nation wouldn't be a great life for a family. It was then that I decided to go work in industry as a Lab Technician and did radio part time, which I did for the majority of the past 36 years (today I have earned a pension from my day job that I've been doing for over 36 years - haven't retired yet).
I'm telling you all this, because you do have a family and you might find that working in radio part time and still keeping your "day job" might be a better route for the stability of your family. This way you get the best of both worlds, the stability (as much as there is in today's economy) in some other field that actually pays the bills, and part time in evenings or weekends in radio where you get to have fun. Sort of a hobby that you get paid to do. Sure beats belonging to a bowling team.
I produced numerous spots, jocked an Oldies format, an 80's format, Big Band - Nostalgia, CCM (Contemporary Christian Music), was a News Anchor/Reporter (I had the opportunity to interview Christiann Almanpour (sp) from CNN, Dr. Robert Ballard (undersea explorer who found the Titanic), and Rev. Desmond Tutu, and had my own talk show for three years. Not too bad for a weekend part timer.
I've met some great people along the way ( I apologize for any names missed as there were more and I can picture the faces, but can't remember the names):
Jim Hicks, Susan Duffield, and Ed Paolini (sp) at 1260 WNRK;
Frank Gerace at both 101.7 WNNN-FM/ 1510 WJIC-AM, and 1380 WAMS (today at WDEL),
Scott Graham (former voice of the Phillies later after his stint at WAMS), Kevin Fennessy(today at WMCA), Bob Charger(today at WOGL), and Todd Halliday all of those folks at 1380 WAMS;
Mark Fowser, Mark Eichmann (today at WHYY-FM), John Lewis (today at WCBM Baltimore), Ted Efaw, Allan Loudell(today at WDEL), Sharon Middleman (today at CBS radio), Matt Cherry (today at WTOP), Tom Byrn (today at WHYY-FM), and John Watson all of these folks at 1450 WILM newsradio.
So even though I didn't go full time into radio, I've had a great experience of doing a large variety of fun things in my favorite medium at numerous stations in the Wilmington area. I worked with some very talented people (see above). My "mini radio career" was a lot of fun, I learned a lot as each person listed above at some point in time while working at their respective station worked with me, assisted me or taught me something I needed to learn, etc. All treated me with respect as a professional even though I was only a weekender.
This might be an avenue for you to consider. In either case, whether you go full time or part time, best of luck.
