Well, I gave up an office job and went back to radio technical work in 1972, and never looked back. I've made a living out of it, and raised a family. Won't make you rich, but it's steady and stable. And, if you have a good idea for developing a new broadcaster's product, you can become quite rich at it. Steve Church and Frank Foti are two who come to mind who've done that.
As a source of basic knowledge, don't overlook the military. Although they are treaining you for a specific position, the basics of electronics are presented as part of the mix... it's up to you to pick it up.
It is currently a seller's market. State your case but don't overstate it, and there's a place for you. One route is to take the 'remnote tech' or 'second assistant' position in a cluster in a medium or large market and use it to learn both the profession and the people in it. A couple or three years learning, plus some training in electronics, and you're ready to step up to assistant or transmitter/studio/remote supervisor for a cluster, or Chief of a small to medium operation. Join the nearest S.B.E. Chapter and network like a bandit.
If you've a good business sense, contract or pickup work can be lucrative.
The caveat in all of this: It's still a small club, and shrinking daily. So, everyone knows everyone else, and knows who do and who don't do, as they say. Don't pick up a poor reputation, it can be very hard to overcome.
It's nopt a bad idea to learn a bit of the other disciplines in broadcasting while you're at it. Leran something of how sales and programming are done, and ask a LOT of questions. Spen an afternoon in the traffic dept, and get a feel for scheduling and log generation. The idea is to figure out what is of value to these people technically. It's a support job, and they're who you're supporting. The idea is to be their solution, not part of their problem.
In a nutshell, go for it. It's fun. And, should it quit being fun for whatever reason, turn your back on it and walk away. Life's too short to do anything you don't enjoy for very long.
