Swiss Broadcasting Corporation to pull plug on FM radio
Switzerland’s plan for its public broadcaster to phase out FM radio in favor of digital audio broadcasting (DAB+) is prompting debate over sound quality, coverage, and resilience. Commenters argue that while DAB+ is more spectrum‑efficient and supports many more channels, it often uses low bitrates, fails abruptly in weak-signal areas, and depends on more complex, less “survival‑friendly” hardware than simple FM sets. Others view the move as driven by cost savings and spectrum reallocation, raising concerns about stranded car radios, emergency alerting, and the broader trend of phasing out analog broadcast infrastructure.
Audio quality and technical tradeoffs
- Several comments question whether DAB/DAB+ actually improves audio quality; many broadcasters use very low bitrates (often 64–96 kbps), leading to audible artifacts and “metallic” sound.
- FM can sound excellent when done well; DAB’s theoretical advantages are often undercut by aggressive compression and stuffing more channels into the multiplex.
- DAB+ (HE-AAC) is seen as technically superior to legacy DAB (MP2) at low bitrates, but still noticeably compressed, especially for music.
- Some note that in marginal conditions analog FM degrades gradually (noise, hiss), while DAB tends to work perfectly until it abruptly fails (“cliff effect”).
Reliability, coverage, and terrain
- Multiple commenters say DAB reception is worse than FM, especially in cars and in mountainous terrain like Switzerland and Norway.
- Others point out DAB’s spectral efficiency and single-frequency networks, but acknowledge this was optimized for more channels rather than longer range or graceful degradation.
Economics, spectrum, and rights-holders
- One line of argument: DAB is optimized to maximize channel count and ad inventory, not listener experience.
- Another: digital standards embed conditional access/DRM hooks, raising fears of pay-per-view radio/TV and recording restrictions.
- Some doubt that DRM is widely used in practice and note that streaming services (Spotify, etc.) have already changed rights economics.
- Future use of vacated FM spectrum is unclear; some expect it to be reallocated or auctioned, others doubt strong alternate demand.
Devices, cars, and user impact
- Many still rely on FM-only car radios; adapters exist but are clunky and not free.
- EU rules now push DAB+ into new cars, but vehicle lifetimes mean many listeners would be stranded for years.
- Old, cheap, easy-to-build FM/AM sets are contrasted with more complex, chip-dependent DAB receivers.
Public broadcasters, fees, and politics
- Swiss FM shutdown is linked by some to SRG/SRF budget politics: cutting visible services to influence an upcoming fee-reduction initiative.
- There’s debate over mandatory broadcast fees, the value of independent public media, and whether state-funded outlets can be truly neutral.
Emergency use and resilience
- Several posts stress analog AM/FM’s value in disasters: simple receivers, easy to re-establish transmitters, low tech dependency.
- Digital-only broadcast and app-based streaming are seen as more fragile and more easily controlled or shut down.
Global comparisons and alternatives
- Examples cited: Norway (FM shut down, many more digital channels), Germany (abandoned a 2015 FM switch-off plan), Ireland and Singapore (largely abandoned DAB), US HD Radio (often poor audio).
- Some argue that FM + internet streaming is a better combination than DAB, making separate digital terrestrial radio questionable.
