My opinion on this is that the radio or whatever is the owner's to do as they please with, and that includes modifying it, even in a non-reversible way, whether by adding FM, DAB or whatever. Obviously no forum member would consider butchering a really rare radio, but if it's a common 50s or 60s model, why does it matter if modifications or additions are made to it? Not quite the same thing, I know, but many years ago I modified a MW Valve superhet to receive SW by changing the coils and padder caps., just to prove it could be done. I don't recall the frequency coverage now, but suspect it was something like 19-49 or 60M.
