Brits are being offered between 10 and 20 percent off the cost of a new digital radio, when they trade in their old analogue model.
DSG International, which owns Currys and Dixons, is a noteable exception from the retailers taking part. The company declined to take part in the scheme because it is currently adjusting its product range.
Pure's DAB radio are among those available with up to 20 percent off as part of the Radio Amnesty
The offer, which has been modelled on the government's car scrappage scheme that saw Brits given £2,000 to purchase a new car if they traded in their older vehicle, has been developed by the BBC and commercial radio stations.
Celebrities including Stephen Fry, Gaby Roslin, Noddy Holder and Gabby Logan will also be showing their support for the scheme during roadcasts.
Traded in radios will be repaired and given to the Children's Radio Foundation in South Africa and UNICEF, in a bid to encourage education and personal growth in under-privileged children through radio programmes.
Those that cannot be repaired will be recycled under the Waste Electrical and Electronic Equipment (WEEE) directive
It is thought the amnesty has been developed in a bid to encourage more Brits to listen to digital radio.
According to Rajar audience figures released in February, digital platforms were responsible for 20.9 percent of all radio listening in the UK between October and December 2009. The organisation said DAB radio accounted for 13.7 of all digital listening.
However, under plans detailed in the Digital Economy Act, the government expects digital platforms to be responsible for half of all UK radio listening by 2013, with a view to switching off analogue radio by 2015.
"Digital radio is the future for UK radio and the radio amnesty gives consumers even more reasons to get digital radio," said Ford Ennals, from industry body Digital Radio UK.
"It is a wonderful example of the UK radio industry coming together to support digital radio and a very worthwhile cause."
