My DAB+ radio also has an FM function. It stores a favorite set of channels for DAB and a separate memory store for FM. When cycling through the DAB presets, there is a ~3 or so second delay for it to tune and decode. With the FM mode there is no delay. Is my particular model just slow with decoding the first sound byte or is this an inherent DAB shortcoming?
I imagine a well designed DAB radio could theoretically tune the next 2 or 3 presets in sequence simultaneously in parallel so you could avoid the channel changing delay. Has anything like that been implemented?
What about a device that pairs FM to DAB? Some radio stations have both an FM and a DAB transmission. So in principle I would want the device to be aware of the dupes. From there, I should be able to flip through the FM stations and once I settle on a station push a single button to switch over to the DAB signal. It could even deliberately play the FM signal for 4 sec. longer and quickly cross-fade in the DAB signal. Any hardware on the market doing this sort of thing?

Pretty much every car with DAB+ works like this. Mainly because it allows instant fallback to FM when you cross into an area without DAB+ reception
