I wonder what is the rationale. Will be shitty if all FM radios become bricks because of some stupid push to obsolete them.

Or is there a smarter plan, like using the bandwidth for something more worthy than FM radio?

UPDATE

Some more FM advantages:

Fast channel changing.

Better reception. There is a station in my city that transmits both DAB and FM. Their DAB signal has chronic cut-outs but their FM station is good enough. And in general, weak FM signals are still useful while weak DAB signals are unusable. So a DAB-only policy marginalises people who live remote from the cities.

Broadcast TV has their shit together, at least in the US. You can setup MythTV to fetch TV schedules without Internet access. It can grab the schedules from the broadcast signals. You can also subscribe to Internet services that give TV scheduling far into the future, but that’s a non-gratis frill. The in-band scheduling info goes a few days out which is good enough.

Radio listeners are screwed on this. FM and DAB+ both have no scheduling info. And worse, there is no Internet service that produces an aggregated radio schedule. You must find websites hosted by each radio station individually and navigate in their shitty user interfaces. Sometimes the programs are too vague to be useful.

Apparently it was completely overlooked in the drafting of the DAB specs. In principle, a clever broadcaster could embed schedule info into the album art using stegonography, or stego on the audio content, but then no appliances would decode such hacks.

I have no idea if satellite radio is on the ball. I think satellite radio is a US-specific option as DAB is nearly non-existent in the US. Vice-versa in Europe.

As someone who has pulled the plug on the residential Internet, I cling to the radio more than most. If DAB would were to include metadata and if there were a DAB-capable PC card, it would be great to have a MythTV-like setup to record radio programs. As it stands, we are driven to do a lot of channel surfing, which is worse on DAB than on FM because of the 2½ second delay with each channel change to decode a chunk of data (so surfing 10 channels has 25 seconds of silent timewaste).

I’m sure radio broadcasters would get more market share if DARs (digital audio recorders) were a thing. That sort of utility might even enable more people to be willing to experiment with unplugging from the Internet.

And of course some of the people involved are also directors of North Norfolk Digital...

I just had a quick look at how album art on a per-track basis reaches tuners. In the US, analog FM radio gets it through a side-channel.. a separate signal called HD radio.

And apparently DAB+ incorporates album art into the signal. This seems to be the difference between DAB and DAB+. I guess the question is, does the HD radio side channel approach ever happen with DAB (non-plus)?

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?

Apologies, seems the receiver/bot is not getting good reception of the HBB mux, hence the repeated "this has been added, oh actually it's gone, oh no it hasn't".

When I can get to the antenna I'll reposition it, or put some mitigations in to stop it happening.

Sometimes DAB radio stations are playing music that skips like a CD, repeating a short segment like a broken record. It often goes on for quite some time, which is a bit puzzling because surely there is nothing about digital radio tech that would cause this. The skipping never happens during talk radio, only with music.

Are radio stations actually playing CDs? If yes, are these CDs also playing on autopilot with no one at the helm to quickly swap out the disc? Or is it just bad timing.. the CD happened to go to shit while the DJ is literally taking a shit and away from the controls?

The skipping was extremely rare, if ever, on analog radio. So I wonder if DAB has also somehow open things up to very low budget stations with robotic DJs, perhaps due to increased sharable bandwidth or something. Switching from analog FM to DAB tripled the number of stations I can receive.

Why don’t they rip their CDs to FLAC files, then listen to the FLAC files for defects to ensure skipping never happens?

Music and radio fans across Bedford are in for a treat with two new DAB radio stations launching this morning (Friday). Community radio station Bedford Radio and commercial station Harpur Radio...

Apparently contains In2beats, Bedford Radio and Angel Vintage.
