John Shepherd, 78, has been giving up his time since 1995 to DJ on the hospital’s radio station.
Alongside is co-host Adam Davey, 32, who has been at the station for 11 years, the duo hosted their final programme last week.
At an emotional final week, fellow volunteers hosted a party in John’s honour.
John ended his presenting career with a six-hour mammoth show playing all his favourite songs.
A farewell meal was held with co-presenters at the Akash in Darwen, and John was presented with a commemorative plaque and a voucher at a local music shop.
Secretary, Melanie Briggs, said: “John is a lovely person and has been a dedicated presenter at Radio Hospitals Blackburn for 30 years. We will all miss him so much.
“Everyone at Radio Hospitals Blackburn and also the volunteer services wish John a very long and happy retirement.”
John began working on the Hospital Radio at the old Park Lee Hospital and then moved to a new studio at what is now Royal Blackburn Hospital.

An East Lancashire Hospitals NHS Trust spokesperson said: “Two of our longstanding radio hospital volunteers, John Shepherd and Adam Davy, hung up their headphones for the last time.
“After 30 years behind the mic, John has decided with a heavy heart to retire from volunteering.
“He recalled nervously arriving for his first shift at the old Park Lee Hospital. After some training, he went on to have his own programme.
“John introduced Adam to volunteering 11 years ago, and he loved it so much he has done it ever since.
“Thank you Adam and John for all your years of dedication.”

The radio provides a unique and tailored broadcasting service to aid the recovery of patients within the Royal Blackburn Hospital.
It also broadcasts on the internet, so patients who are looking to recover at home will still be able to listen.
The radio covers Blackburn, Darwen, Burnley, Hyndburn, Ribble Valley and surrounding areas.
It is a self-funded charity organisation and sources income from sponsors and local businesses who donate money.
