Welcome to Jonathan Mosen's Mushroom FM page

About Me

I’m Jonathan Mosen, the host of The Smorgasbord, which airs week days at 2 AM Eastern time, repeated 12 hour later. Hey, don't judge, 2 AM Eastern is a highly civilised 6 PM in New Zealand in winter.

No matter what time the show airs where you are, I hope you'll make the Smorgasbord a regular part of your week-day routine. There's a great blend of music from the 50s through to the 80s. I also throw in a lot of friendly conversation, and a tech news story or two when interesting things are happening.

That leaves the show I've been doing for more years than I care to remember, and it's that show that this page is predominantly about. the Mosen Explosion airs most Saturdays at 2 Pm Eastern, 7 PM in the UK. That’s Sunday morning where I live. In winter time, the show starts bright and early at 6 AM in New Zealand, while when we're on daylight saving time, it's a more civilised 8 AM.

Sometimes, I get asked why on earth I get up at such an early hour to host a voluntary Internet radio show. First, I love the medium, so any time's a good time to do radio. But the early hour takes me back to my commercial radio career, where I used to stagger out of bed at 3:30 AM for a 6 AM start. There's a certain kind of energy about the morning shows, and I try to bring that to the Mosen Explosion.

I’ve been involved with radio from a very early age, having begun being heard by radio listeners in my home town of Auckland, New Zealand, from the age of four. I always wanted to work in broadcasting, so while I was still at high school, I established a licensed radio station at the school for the blind, to demonstrate that blindness was no barrier to working in broadcasting. We funded the whole thing with advertising, and I made many useful radio contacts through inviting them out for a look and to guest host a show.

During and after completion of my degrees in History and Political Science, I worked on a number of commercial radio stations both in broadcasting, and administration.

When it was time to start a family however, the crazy deregulated radio market at the time in New Zealand, where stations were regularly changing owners and formats, was no stable place to be. So I’ve worked in other fields such as Government relations and information technology.

While on the Government relations track, I went back to University to complete a Master’s degree in Public Policy. Radio, though, is my first love.

I’ve run a number of low power community FM stations, some of which streamed on the Internet, and founded ACB Radio in 1999, which I directed for 4 years.

I’ve stood for Parliament twice but the people were too sensible to elect me, been the Chairman of the Board of New Zealand’s blindness agency and the President of our blindness consumer organisation (but of course not at the same time), and am a registered hypnotherapist.

I love a wide range of music, but am a fanatical Beatles fan and collector. I enjoy public speaking, politics from around the world, radio drama but not Twitter drama, good healthy low-carb food, cricket, stimulating conversation, and spending time with my beautiful wife Bonnie and four children, two girls and two boys. Oh, and the cool son-in-law too, I mustn't forget him.

In my day job, I'm Chief Executive of Workbridge, New Zealand's leading provider of employment services for disabled people.

In 2019, I was made a Member of the New Zealand Order of Merit.

About the Show

Presented from Wellington, the capital of New Zealand, from studios at Mosen Towers, the Mosen Explosion is four hours of radio that’s full of fun, spontaneity, listener interaction and the very best music ever made.

I try to make the show like the ones I enjoyed listening to as a kid, with plenty of jingles, use of funny little audio snippets and a fast pace.
Special features include:
• The Banana Report, where the Mosen kids get let loose on the air and say who knows what.
• Today in history, often with a few little observations thrown in and appropriate music to match
• The Bonnie Bulletin, where Bonnie Mosen chronicles her experiences as an American downunder

But mostly, we spend our time playing a huge variety of great music. If I have it, I’ll play it, no matter what the genre or when it was made. Much of what we play is driven by you, and that’s the way we like it.

If you’re a new listener, we’ll induct you as a friend of the show by exploding you. Yes, this is one place where being exploded is actually a good thing!
