Since 2000, our annual sweepstakes has tasked our readers with finding the mic icon on each cover from the previous year. The icon, like the ones shown below, is placed on every cover of Radio magazine.

While the mic icon is part of the logo and is also used in the 10 Years logo, the challenge was to find the hidden icon placed on the cover. Sometimes it was easy to find. Sometimes it was a real challenge.

We received a large number of responses, of which more than half correctly identified all 13 cover locations (12 monthly issues plus the September Product Source).

The entries with all 13 correct answers were placed into a random drawing for the three prizes.

Be sure to save each issue of Radio magazine so you can enter next year's sweepstakes.

And if you had trouble finding the mic, here are the correctlocations:

On the left computer display above the console
February: Just above the rear tire of the KASE van
March: The cue speaker on the Otari console
