Anyone can do a podcast, about almost anything. You'll notice we talk about riding in rental cars & getting lost, what kind of soda pop we like (and don't like), etc. etc. etc. Just get something about 2WD R/C in there someplace, keep it clean, and do it in English. You can do it yourself, you can interview someone else or more than one person, a group can do the podcast, it doesn't matter.
We are not professional broadcasters -- whatever comes out is just fine. You should not be using an high-quality professional mike, and you definitely should not be in a studio -- background noise and static are par for the course. Leaving long pauses as you search for something to say is almost required.
They can be as short as 30 seconds or as long as you like. Just record them digitally and E-mail them to chazz@2wdrc.com. Again, you can send as many as you want, as often as you want!
