A guess the sound competition on BOB fm has been won after almost two years of guessing from listeners.
Breakfast presenter Graham Mack gave away a prize of £3,020 to a listener after he correctly guessed “What’s BOB doing” at the Home Counties station.
The prize started out in September 2014 at £106 and every time Graham played the sound of what BOB was doing, the money went up by at least £5.
Adam worked out that BOB was plugging his mobile phone charger into the cigarette lighter socket in his car.
