Radio 2 DJs Chris Evans and Jonathan Ross are going head to head in the race to be named personality of the year at the 25th Sony Radio Awards.
The DJs face competition from Andy Kershaw and Mark Radcliffe
Evans, who took the title last year, is also up for the entertainment award, alongside Heart's Jamie Theakston and last year's winner, Chris Moyles.
BBC stations dominate the nominations, with Radio 4 listed 23 times.
Commercial stations Heart and XFM each have three nominations. The awards will be announced in London on 30 April.
Sir Terry Wogan, who has the most listened-to radio programme in the UK, has not received a nomination for his breakfast show on BBC Radio 2.
Instead, the contenders are Radio 4's Today Programme, Five Live Breakfast and three regional shows - The Bush and Troy Show from GWR in Bristol, Toolan in the Morning from Manchester's Key 103 and the Jo and Twiggy Breakfast show from Trent FM.
But Wogan is up for the Broadcasters' Broadcaster Award, which is being run to coincide with Sony Radio Academy's 25th anniversary.
Wogan won the Gold Award outstanding achievement in 2006
The award will see one of 25 "individuals who have shaped, changed and developed modern radio broadcasting" recognised for their contribution.
The shortlist also includes Kenny Everett, John Peel, Chris Moyles, Annie Nightingale and Sir Alistair Cooke, with the winner to be chosen by fellow broadcasters.
For the first time, this year's Sony Awards will recognise online broadcasters, with Frank Skinner and David Baddiel's World Cup podcasts in the running for the internet programme award.
Channel 4's online station 4Radio even makes an appearance in the music programme category, alongside four traditional radio stations.
Its Popworld Radio challenges Radio 1's Zane Lowe, which won the award last year.
Former Inspiral Carpets star Clint Boon gets a double nomination - music broadcaster of the year and specialist music programme - for his show on XFM Manchester.
Radio 1 is defending its title of station of the year against competition from Radio 2 and Classic FM.
"It is testimony to the respect in which these awards are held that after 25 years of their existence, this year's event attracted the all-time highest number of entries," said chairman of the awards committee, Tim Blackmore.
