From 9 to 14 August 2007, Walker was one of several former pirate radio disc jockeys at BBC Essex's six-day revival of pirate radio marking the 40th anniversary of the Marine Offences Act. He was also part of "Pirate BBC Essex" programmes broadcast over Easter 2009 to celebrate 45 years since the launch of Radio Caroline. On Saturday 7 February 2009, Walker began a new ten-week series called Pirate Johnnie Walker on BBC Radio 2. This show recreated the sounds of pirate radio from the 1960s, and had other Pirate DJs from the era as guests.

On 30 March 2012, he launched his "Alternative Johnnie Walker" podcast which aimed to "Open the door to an alternative view of the world featuring inspirational and radical thinkers dedicated to improving life on Planet Earth."

The couple also collaborate on a podcast called Consciously Coupling. On August 14th 2022 Walker hosted a show on Boom Radio as part of the station's celebration of Offshore Radio.
