Obviously a DRM receiver can handle both analogue and digital signals. Once a DRM signal is received, all parallel frequencies of the service are automatically stored in the receiver's memory. If the signal becomes weak the receiver will automatically switch to a better signal (if available), even in other bands. With a small amount of digital information added to an existing analogue AM broadcast (AMSS, AM Signalling System) the receiver recognizes the alternative frequency information and schedules for other DRM, DAB, AM and FM transmissions carrying the same or related programme material. When you tune in to an analoque AM transmission on 630 kHz in the medium wave band the receiver could let you listening to for instance a DRM broadcast on 9740 kHz on short wave. > Are any such autoswitching receivers currently available?
