Buy a broadcaster mic. A blue mouse is great the ev re20, sennheiser md421...list goes on.

experimenting with mics an eq can help (add the sm7 to that list)... but alot of it is also technique... you'll hear vocalists talk about a "head voice"... well this is a "chest voice"... try to get it to resonate in your chest...

The deep resonate voice you hear on the radio is a product of what is known in the professional audio world as Proximity Effect. It is basically the increase of bass as you get closer to the microphone. It is prevelent on almost all Dynamic microphones and most low-end condensors.
It also does help to have a deep voice but the bassy "sexy" voice is helped along by speaking very closely to a microphone

And noone have even touched the subject COMPRESSOR.
All radio is compressed to death!. They even compress the classic channel here in norway.

All the posters are right but the most important factor is your voice. If you do not have that thick "radio voice" in the first place, technology wont help you much.

True true.
Sh*t in equals sh*t out. as they say.

You cant make gold from anything that comes out an horses arse.. :P or something..
Anywho. point made.

Lots of radio stations use what is commonly referred to as a voice processor. It is a muti functional device. It has a mic preamp, an equalizer, a compressor and limiter (and may have some more "effects") built into it. Some of the fancier versions also have cards that you can setup all your presets and then save them to the card. In station with lots of DJs they can customize their "sound" just by inserting their own card in the processor. What has been said already is very good advice. If you are getting too much room sound put two 2 foot by 2 foot pieces of Auralex in a corner of the room at head level and put your microphone in the middle of the Auralex facing the room and then put a third piece of Auralex behind your head mounted on a stand. You will then have a mini vocal booth and it should cut down on the 'room tone" which is what you are hearing. As in computers garbage in garbage out so get the best microphone for your voice, a good microphone preamp and three pieces of Auralex and go to town. If you are having problems with the sound of your voice a good vocal coach maybe a good idea as they can spot problems that you are not aware of. Most cities have vocal coaches but if you can't find one then contact a local college or university with a speech department and ask for references.

Best of luck!
